Knowing whether a room is occupied or not is crucial for improving electrical energy efficiency. For instance, if a given room is empty there is usually no need for the lights to be turned on. Usually in small spaces such as elevator halls, a Passive Infrared (PIR) sensor is used together with the lighting, but as it lacks accuracy, people often are left in the dark after a few minutes. Another factor that deteriorates energy efficiency is that these sensors are seldom connected to a network, limiting the application scenarios to simple tasks, such as controlling lamps. The same data could be used to improve other services such as adjusting the temperature of an air conditioner, which usually has a high impact on energy costs in countries with warm weather. In the present dissertation a wireless device capable of counting people in a room is implemented using Infrared (IR) Light Emitting Diode (LED)s. The implemented device is analyzed regarding energy consumption, cost, error count and installation time. It is also compared to other existing solutions. An architecture for interfacing this device with the Internet of Things (IoT) is provided as well as some of its applications in real scenarios. The results show that the architecture provided as well as the device implemented are useful in the presented scenarios, presenting a distance range of up to 30cm, a false negatives percentual error around 4% and an energy consumption of 1.519W.
Saber se um cômodo está ocupado ou não é crucial para melhorar a eficiência de energia elétrica. Por exemplo, se um quarto está desocupado, geralmente, não há necessidade de as lâmpadas estarem ligadas. Geralmente, em ambientes pequenos como em halls de elevador, um sensor Infravermelho Passivo (PIR) é usado em conjunto com as lâmpadas, mas como estes sensores não são precisos, as pessoas são frequentemente deixadas no escuro após alguns minutos. Outro fator que prejudica a eficiência energética é que raramente estes sensores estão conectados a uma rede, limitando os cenários de aplicação a tarefas simples, como controlar lâmpadas, enquanto os dados do sensor poderiam ser utilizados para melhorar outros serviços, como ajustar a temperatura de um aparelho de ar condicionado, que geralmente tem um alto impacto nas contas de energia, em países quentes. Nesta dissertação, um dispositivo sem fio capaz de contar pessoas em um quarto é implementado utilizando Diodos Emissores de Luz (LED)s Infravermelhos (IR). O dispositivo implementado é analisado nos seguintes aspectos: consumo de energia, custo, contagem de erros e tempo de instalação. Este também é comparado a outras soluções existentes. Uma arquitetura para fazer a interface entre este dispositivo e a Internet das Coisas (IoT) é fornecida, assim como alguns cenários em que esta pode ser aplicada. Os resultados mostram que a arquitetura, assim como o dispositivo implementado são úteis nos cenários apresentados, apresentando um alcance de 30cm, um percentual de erros do tipo falso negativo da ordem de 4% e um consumo de energia de 1.519W.

Abstract. Edge services are needed to save networking and computational resources on higher tiers, enable operation during network problems, and to help limiting private data propagation to higher tiers if the function needing it can be handled locally. MEC at access network level provides most of these features but cannot help when access network is down. Local services, in addition, help alleviating the MEC load and limit the data propagation even more, on local level. This thesis focuses on the local IoT service provisioning. Local service provisioning is subject to several requirements, related to resource/energy-efficiency, performance and reliability.
This thesis introduces a novel way to design and implement a Docker container-based micro-service system for gadget-free future IoT (Internet of Things) network. It introduces a use case scenario and proposes few possible required micro-services as of solution to the scenario. Some of these services deployed on different virtual platforms along with software components that can process sensor data providing storage capacity to make decisions based on their algorithm and business logic while few other services deployed with gateway components to connect rest of the devices to the system of solution. It also includes a state-of-the-art study for design, implementation, and evaluation as a Proof-of-Concept (PoC) based on container-based microservices with Docker. The used IoT devices are Raspberry Pi embedded computers along with an Ubuntu machine with a rich set of features and interfaces, capable of running virtualized services.
This thesis evaluates the solution based on practical implementation. In addition, the thesis also discusses the benefits and drawbacks of the system with respect to the empirical solution. The output of the thesis shows that the virtualized microservices could be efficiently utilized at the local and resource constrained IoT using Dockers. This validates that the approach taken in this thesis is feasible for providing such services and functionalities to the micro

La virtualizzazione permette a diverse applicazioni di condividere lo stesso dispositivo IoT. Tuttavia, in ambienti eterogenei, reti di dispositivi IoT virtualizzati fanno emergere nuove sfide, come la necessità di fornire on-the-fly e in maniera dinamica, elastica e scalabile, gateway. NFV è un paradigma progettato per affrontare queste nuove sfide. Esso sfrutta tecnologie di virtualizzazione standard per consolidare specifici elementi di rete su generico hardware commerciale. Questa tesi presenta un'architettura
NFV per gateway IoT distribuiti, nella quale istanze software dei moduli dei gateway sono ospitate su un'infrastruttura NFV distribuita, la quale è operata e gestita da un IoT gateway Provider. Considereremo diversi IoT Provider, ciascuno con le proprie marche, o loro combinazioni, di sensori e attuatori/robot. Ipotizzeremo
che gli ambienti dei provider siano geograficamente distribuiti, per un'efficiente copertura di regioni estese. I sensori e gli attuatori possono essere utilizzati da una varietà di applicazioni, ciascuna delle quali può avere diversi requisiti per interfacce e QoS (latenza, throughput, consumi, ecc...). L'infrastruttura NFV consente di effettuare un deployment elastico, dinamico e scalabile dei moduli gateway in questo ambiente eterogeneo e distribuito. Inoltre, l'architettura proposta è in grado di riutilizzare moduli il cui deployment è stato precedentemente compiuto. Ciò è ottenuto
attraverso Service Function Chaining e un'orchestrazione dinamica a runtime. Infine, presenteremo un prototipo basato sulla piattaforma OpenStack.

Industry 4.0 springs from the fourth industrial revolution, which is bringing innovation to fully automated and interconnected industrial production. This movement is composed of macro areas to expand the technological horizon starting from the tools used to date. The use of data, computing power and connectivity are the fundamental concepts on which the study of this thesis is based and are declined in big data, open data, Internet of Things (IoT), machine-to-machine and cloud computing for the centralization of information and its storage. Once the data has been collected, it is necessary to derive value from it in order to obtain advantages from ”machine learning”, i.e. machines that improve their performance by ”learning” from the data collected and analyzed.
The advent of the Internet of Things can be seen in all respects as the greatest technological revolution of recent years, which will bring a huge amount of information into the hands of users. The latter can offer countless advantages in daily life and in the diagnostics of the production process.
Industrial IoT (IIoT) enables manufacturing organizations to create a communication path through the automation pyramid, obtaining a real data stream in order to improve the machine performances. From an information security point of view, the importance of the information transmitted should not be underestimated and this also concerns an important aspect of industry 4.0. Protocols and authentication systems are constantly updated to ensure the privacy and security the customer needs.
Through this thesis project, the implementation requirements will be dealt with in order to study and analyze different vendor technologies and to construct a cloud architecture. The focus is concentrated on the cybersecurity and on the information losses avoidance in order to get a robust transfer.

Mestrado em Sistemas de InformaçãoDesde o início da primeira década do presente milénio, tem-se testemunhado um aumento exponencial da quantidade de dados produzidos de dia para dia. Numa primeira instância, o aumento foi atribuído aos dados gerados pelos dispositivos GPS; numa segunda fase, à rápida expansão das redes sociais, agora não devido a um fator específico, mas devido ao surgimento de um novo conceito denominado de Internet das Coisas. Este novo conceito, com resultados já mensuráveis, nasceu da premissa de facilitar o dia-a-dia das pessoas fazendo com que os dispositivos eletrónicos comunicassem entre si com o objetivo de sugerir e assistir a pequenas decisões dado os comportamentos observados no passado. Com o objetivo de manter o conceito possível e o estender para além das já existentes aplicações, os dados gerados pelos dispositivos necessitam não apenas de serem armazenados, mas igualmente processados. Adicionando ao volume de dados a sua variedade e velocidade de produção, estes são igualmente fatores que quando não ultrapassados da maneira correta podem apresentar diversas dificuldades, ao ponto de inviabilizarem a criação de novas aplicações baseadas neste novo conceito. Os mecanismos e tecnologias existentes não acompanharam a evolução das novas necessidades, e para que o conceito possa evoluir, novas soluções são obrigatórias. A liderar a lista das novas tecnologias preparadas para este novo tipo de desafios, composto por um sistema de ficheiros distribuído e uma plataforma de processamento distribuída, está o Hadoop. O Hadoop é uma referência para a resolução desta nova gama de problemas, e já comprovou ser capaz de processar enormes quantidades de dados de maneira económica. No entanto, dadas as suas características, tem alguma dificuldade em processar menores quantidades de dados e tem como desvantagem a grande latência necessária para a iniciação do processamento de dados. Num mercado volátil, ser capaz de processar grandes quantidades de dados baseadas em dados passados não é o suficiente. Tecnologias capazes de processar dados em tempo real são igualmente necessárias para complementar as necessidades de processamento de dados anteriores. No panorama atual, as tecnologias existentes não se demonstram à prova de tão distintas necessidades e, quando postas à prova, diferentes produtos tecnológicos necessitam ser combinados. Resultado de um ambiente com as características descritas é o ambiente que servirá de contexto para a execução do trabalho que se segue. Tendo com base as necessidades impostas por um caso de uso pertencente a IoT, através da arquitetura Lambda, diferentes tecnologias serão combinadas com o objetivo de que no final todos os requisitos impostos possam ser ultrapassados. No final, a solução apresentada será avaliada sobre um ambiente real como forma de prova de conceito.
Since the beginning of the first decade of current millennium, it has been witnessed an exponential grow of data being produced every day. First, the increase was given to the amount of data generated by GPS devices, then, the quickly arise of social networks, and now because a new trend as emerged named Internet of Things. This new concept, which is already a reality, was born from the premise of facilitating people's lives by having small electronic devices communicating with each other with the goal to suggest small daily decisions based on the behaviours experienced in the past. With the goal to keep this concept alive and extended further to other applications, the data produced by the target electronic devices is however need to be process and storage. The data volume, velocity and variety are the main variables which when not over planned on the correct way, a wall is created at the point of enviabilize the leverage of the true potential of this new group of applications. Traditional mechanisms and technologies did not follow the actual needs and with the goal to keep the concept alive the address of new technologies are now mandatory. On top of the line, leading the resolution of this new set of challenges, composed by a distributed file system and a parallel processing Framework is Hadoop. Hadoop have proven to fit under the new imposed challenges being capable of process and storage high volumes of data on a cost-effective batch-oriented way. However, given its characteristics on other hand it presents some drawbacks when faced with small amounts of data. In order to gain leverage on market, the companies need not only to be capable of process the data, but process it in a profitable way. Real time processing technologies are needed to complement batch oriented technologies. There is no one size fits all system and with the goal to address the multiples requirements, different technologies are required to be combined. Result of the demanding requirements imposed by the IoT concepts, is the environment which on will be relied the address of the business use case under analyses. Based on the needs imposed by a use case belonging to IoT, through the Lambda architecture, different technologies will be combined with the goal that in the end all the imposed requirements can be accomplished and exceeded. In the end, the solution presented will be evaluated on a real environment as proof of concept.

Abstract. The involvement of low power Internet of Things (IoT) devices in the Wireless Sensor Networks (WSN) allow enhanced autonomous monitoring capability in many application areas. Recently, the principles of edge computing paradigm have been used to cater onsite processing and managing actions in WSNs. However, WSNs deployed in remote sites require human involvement in data collection process since internet accessibility is still limited to population dense areas. Nowadays, researchers propose UAVs for monitoring applications where human involvement is required frequently. In this thesis work, we introduce an edge-based architecture which create end-to-end secure communication between IoT sensors in a remote WSN and central cloud via UAV, which assist the data collection, processing and managing procedures of the remote WSN. Since power is a limited resource, we propose Bluetooth Low Energy (BLE) as the communication media between UAV and sensors in the WSN, where BLE is considered as an ultra-low power radio access technology. To examine the performance of the system model, we have presented a simulation analysis considering three sensor nodes array types that can realize in the practical environment. The impact of BLE data rate, impact of speed of the UAV, impact of distance between adjacent sensors and impact of data generation rate of the sensor node have been analysed to examine the performance of system. Moreover, to observe the practical functionality of the proposed architecture, prototype implementation is presented using commercially available off-the-shelf devices. The prototype of the system is implemented assuming ideal environment.

Internet of Things (‘IoT’) systems are complex, asynchronous solutions often comprised of various software and hardware components developed in isolation of each other. These components function with different degrees of reliability and performance over an inherently unreliable network, the Internet. Many IoT systems are developed within silos that do not provide the ability to communicate or be interoperable with other systems and platforms. Literature exists on how these systems should be designed, how they should interoperate, and how they could be improved, but practice does not always consult literature.
The work brings together a proposed reference architecture for the IoT and engineering practices for flow semantics found in existing literature with a commercial implementation of an IoT platform. It demonstrates that the proposed IoT reference architecture and flow-service-quality engineering practices when integrated together can produce a more robust system with increased functionality and interoperability. It shows how such practices can be implemented into a commercial solution, and explores the value provided to the system when implemented. This work contributes to the current understanding of how complex IoT systems can be developed to be more reliable and interoperable using reference architectures and flow semantics. The work highlights the value of integration of academic solutions with commercial implementations of complex systems.

Internet of Things (IoT) has revolutionized transportation systems by connecting vehicles consequently enabling their tracking, as well as monitoring of driver activities. The IoT platform for most vehicles typically consists of 1) an on-board system consisting of the communication unit, sensors and a set of ECU’s that are interconnected using a CAN network, 2) an off-board system consisting of the applications deployed on the servers (e.g., cloud) that processes the data send by the communication unit over the internet, and 3) mobile devices like a mobile phone or a computer that communicates with the on-board and off-board systems. Such an IoT platform requires a significant amount of data to be send from the on-board system to the off-board servers, contributing to high network usage. There are two main architectural paradigms for sending data: 1) interval based architecture, in which data is send at regular intervals and 2) event based architecture, in which data is send whenever relevant events occur. Currently, (e.g., at Scania), the data is being send at regular intervals, i.e., using an interval based approach. In this case, data is send even if it is not relevant for reporting leading to a wastage of network resources, e.g., when the data does not change considerably compared to the previously sent value. Sending data in an event-based manner, when the data is relevant for reporting, e.g., changes significantly, reduces the network usage when compared to the interval based approach. In this thesis, we investigate the possibility of using an event based architecture to send data from the on-board system to the off-board system in order to reduce network usage and improve the accuracy of the data available off-board. We first propose an event based architecture for data transfer in the context of Internet of vehicles. We then implement a simulator to evaluate our proposed architecture for the specific case of position data. Finally, we perform extensive experiments varying different parameters and compare, for example, average message size per minute and average off-board error distance. The results show that our event based architecture improves the accuracy of data available at the off-board system, by a careful selection of events. Moreover, we found that our event based architecture significantly decreases the frequency of sending messages, particularly during highway driving, leading to reduced average data transfer rates. Our results enable a customer to perform trade-offs between accuracy and data transfer rates. Future work will aim at implementing the event based architecture on a real platform as well as investigating the possibility of using the event based architecture for more accurate prediction by incorporating additional details such as the final destination of the vehicle and odometer values.

Despite the increasing interest in blockchain as a possible solution to replace centralized IoT architectures, previous work failed to provide a direct role for the sensing devices, i.e., direct interaction with the blockchain without additional components. Moreover, few studies focus on permissionless blockchains, even if it is the most secure platform for developing blockchain-based applications.
This thesis presents an architecture that considers constrained sensing devices as direct actors on a public blockchain network. A public blockchain network allows the seamless inclusion of several unknown actors, and smart contracts provide a platform to develop complex IoT applications. The research followed an iterative DSR approach; designing, building, and evaluating new IT artifacts using two case studies in the agricultural IoT domain. These cases fostered two exploratory studies that diverged from the main IoT domain; however, they also provide novel contributions to blockchain-based applications. Thus, the novel architecture tackles three problems of current blockchain-based IoT systems i) constrained sensing devices as direct actors on a blockchain system, ii) permissionless blockchain networks and iii) smart contracts as an IoT application platform. Furthermore, the exploratory analyses examine two challenges of blockchain-based applications i) user experience and monetary costs and ii) data sharing and decentralized storage.

yesThe current electricity grid suffers from numerous challenges due to the lack of an effective energy management strategy that is able to match the generated power to the load demand. This problem becomes more pronounced with microgrids, where the variability of the load is obvious and the generation is mostly coming from renewables, as it depends on the usage of distributed energy sources. Building a smart microgrid would be much more economically feasible than converting the large electricity grid into a smart grid, as it would require huge investments in replacing legacy equipment with smart equipment. In this paper, application of Internet of Things (IoT) technology in different parts of the microgrid is carried out to achieve an effective IoT architecture in addition to proposing the Internet-of-Asset (IoA) concept that will be able to convert any legacy asset into a smart IoT-ready one. This will allow the effective connection of all assets to a cloud-based IoT. The role of which is to perform computations and big data analysis on the collected data from across the smart microgrid to send effective energy management and control commands to different controllers. Then the IoT cloud will send control actions to solve microgrid's technical issues such as solving energy mismatch problem by setting prediction models, increasing power quality by the effective commitment of DERs and eliminating load shedding by turning off only unnecessary loads so consumers won't suffer from power outages. The benefits of using IoT on various parts within the microgrid are also addressed.

Au cours des quinze dernières années, le développement de plateformes embarquées intelligentes et les progrès des protocoles de communication radio ont permis l'émergence de réseaux de capteurs sans-fils (WSN). D'autre part, la démocratisation d'Internet et du Web, ainsi que l'augmentation des débits ont contribué à l'essor d'un nouveau paradigme : le Cloud computing. L'Internet des Objets, (IoT) ou Internet des Objets réalise la convergence entre les réseaux de capteurs et le Cloud computing. De nombreux travaux adressant les problématiques de l'IoT ont étés menés ces dix dernières années, cependant ces propositions manquent ne tiennent pas suffisamment compte des problématiques de sécurité et de protection des données. D'après Gartner, 70 % des plateformes déployées ne disposent pas d'une solution de sécurité efficace, les rendant vulnérables aux attaques. Dans le domaine des monnaies numériques, Bitcoin propose en son sein une nouvelle structure de données authentifiée et trustless permettant la décentralisation de l'enregistrement de transactions en s'appuyant sur un protocole permettant d'obtenir un consensus : la blockchain. Cette thèse se focalise sur l'utilisation de cette nouvelle structure de données dans les WSN dans un contexte IoT, comme base pour la définition d'une architecture sécurisée et adaptative basée sur la blockchain. Le but de cette architecture est d'intégrer les solutions existantes pour l'organisation du réseau et l'accès aux services de manière innovante afin de réaliser l'intégration des WSN avec l'infrastructure web; mais aussi d'y adjoindre une solution répondant aux nouveaux besoins de sécurités et contraintes spécifiques des réseaux de capteurs. Nous proposons pour cela un framework nommé Network Service Loader (NSL) en charge de la gestion de services et d'agents mobiles, auquel s'adjoint notre solution Blockchain Authentication and Trust Module (BATM) en charge de l'authentification, du contrôle d'accès, ainsi que des évaluations de confiance via l'algorithme Maximum Likelihood Trust Estimator (MLTE)During the last fifteen years, the rise of smart and wireless enabled embedded devices lead to the development of wireless sensor networks (WSN). In the same time, the emerging of Cloud computing with the development of the Internet and the Web as an everyday technology thanks to the rise of bandwidth and processing power leads to new network paradigms. The Internet of Things (IoT) primary goal is to bridge the gap between these technologies and bring WSN sensing and actuating abilities to Cloud applications. We count a significant amount of work targetting the IoT in the last decade, however they lack proper solutions to ensure data privacy and security. Gartner investigations shows that 70 % of connected and smart devices provide little or no security policies and solutions, making both user and devices vulnerable to attackers. In the field of digital currencies, Bitcoin proposed a new authenticated and trustless data structure dedicated to transactions logging in a decentralized network with the help of a consensus protocol : the blockchain. This thesis is focused on bringing the blockchain technology as a new solutions for security in decentralized WSN in the IoT, providing the basis for a secure and adaptative agent-based middleware and execution framework. This framework attempt to federate existing work regarding the architecture of the IoT, but also to tackle security issues regarding network access, agent execution and trust evaluation. To achieve this goal, we propose Network Service Loader (NSL), an agent-based middleware constructed of existing protocols in a new way, along with a new solution called Blockchain Authentication and Trust Module (BATM) dedicated to node and users authentication, access control policies, and trust evaluation through our new Maximum Likelihood Trust Estimator (MLTE) algorithm

As the number of Internet of Things (IoT) devices that are used daily is increasing, the inadequacy of cloud computing to provide neseccary IoT-related features, such as low latency, geographic distribution and location awareness, is becoming more evident. Fog computing is introduced as a new computing paradigm, in order to solve this problem by extending the cloud‟s storage and computing resources to the network edge. However, the introduction of this new paradigm is also confronted by various security threats and challenges since the security practices that are implemented in cloud computing cannot be applied directly to this new architecture paradigm. To this end, various papers have been published in the context of fog computing security, in an effort to establish the best security practices towards the standardization of fog computing. In this thesis, we perform a systematic literature review of current research in order to provide with a classification of the various security threats and challenges in fog computing. Furthermore, we present the solutions that have been proposed so far and which security challenge do they address. Finally, we attempt to distinguish common aspects between the various proposals, evaluate current research on the subject and suggest directions for future research.

In this case, a very important property is the fixed ratio an identifier with the actual device of the Internet of Things (physical address), as well as versatility in the application of the identifier in various industries. In the DOA architecture, the resolution system is two-tier.

For permission identifier in this subsystem, first there is an appeal to the global registry GHR, which reports information about the local LHR, which contains necessary information about the digital object.

This thesis work is based on the literature studies and a detail evaluation of Service Node application in order to investigate how an IoT network can be setup to achieve automation with service andmaintenance of smart building environment. A building in the context of this thesis work is a multistoried residential or commercial facilities having equipments and machineries such as elevator, ventilation, and equipment for managing powers and energy consumption etc. The literatures for this study are carefully chosen in order to find the components that would form the IoT network that is suitable in the context of smart building environment. The result from the studies are then compared with the evaluation made on an application called Service Node and an improvement to its present architecture is suggested. There was no re-inventing the wheel rather anarchitecture was proposed using the existing technologies and protocols to address the issues with services and maintenances of the equipment commonly found in a building which are prone to faults and requires periodical maintenance.

Fog Computing is an emerging computing paradigm that shifts certain processing closer to the Edge of a network, generally within one network hop, where latency is minimized, and results can be obtained the quickest. However, not a lot of research has been done on the effectiveness of Fog in real-world applications. The aim of this research is to show the effectiveness of the Fog Computing paradigm as the middle layer in a 3-tier architecture between the Internet of Things (IoT) and the Cloud. Two applications were developed: one utilizing Fog in a 3-tier architecture and another application using IoT and Cloud with no Fog. A quantitative and qualitative analysis followed the application development, with studies focused on application response time and walkthroughs for AWS Greengrass and Amazon Machine Learning.
Furthermore, the application itself demonstrates an architecture which is of both business and research value, providing a real-life coffee shop use-case and utilizing a newly available Fog offering from Amazon known as Greengrass. At the Cloud level, the newly available Amazon Machine Learning API was used to perform predictive analytics on the data provided by the IoT devices. Results suggest that Fog-enabled applications have a much lower range of response times as well as lower response times overall. These results suggest Fog-enabled solutions are suitable for applications which require network stability and reliably lower latency.

The contact patterns among individuals can significantly affect the progress of an infectious outbreak within a population. Gathering data about these interaction and mixing patterns is essential to assess computational modeling of infectious diseases. Various self-report approaches have been designed in different studies to collect data about contact rates and patterns. Recent advances in sensing technology provide researchers with a bilateral automated data collection devices to facilitate contact gathering overcoming the disadvantages of previous approaches. In this study, a novel unilateral wearable sensing architecture has been proposed that overcome the limitations of the bi-lateral sensing. Our unilateral wearable sensing system gather contact data using hybrid sensor arrays embedded in wearable shirt. A smartphone application has been used to transfer the collected sensors data to the cloud and apply deep learning model to estimate the number of human contacts and the results are stored in the cloud database. The deep learning model has been developed on the hand labelled data over multiple experiments. This model has been tested and evaluated, and these results were reported in the study. Sensitivity analysis has been performed to choose the most suitable image resolution and format for the model to estimate contacts and to analyze the model's consumption of computer resources.

De nos jours, de nombreuses applications IoT sont devenues une partie essentielle de la vie des gens, des industries et des écosystèmes modernes. La plupart des applications IoT sont basées sur un système centralisé dans lequel tous les participants au système doivent s'en remettre à une entité centrale. Dans un tel système, l'immuabilité, la traçabilité et la transparence des données ne peuvent être assurées. La technologie Blockchain est un système entièrement décentralisé dans lequel le tiers de confiance (entité centrale) est supprimé. La particularité de cette technologie est qu'elle prévoit qu'une fois que les données y sont déployées, elles ne peuvent pas être modifiées ou retirées du système. Contrairement aux systèmes centralisés, la blockchain assure la traçabilité et la transparence des données. La plupart des blockchains modernes permettent également le déploiement de Smart Contracts, qui sont des programmes numériques pouvant être lus par tous les participants et exécutés automatiquement en fonction d'un événement sur la blockchain. Les caractéristiques avantageuses de la technologie blockchain montrent un intérêt évident pour l'intégration des IoT avec la technologie blockchain.Cette contribution de thèse étudie les possibilités d'intégration des IoT avec la technologie blockchain. L'une des principales parties de la contribution est le développement d'un modèle d'architecture matérielle IoT dédiée à faible consommation d'énergie qui permet la communication avec plusieurs types de blockchains. Le modèle d'architecture est composé d'un CPU basé sur ARM émulé sur QEMU et d'accélérateurs matériels cryptographiques modélisés dans le langage de description matérielle de haut niveau SystemC-TLM. Un système d'exploitation (OS) Linux est exécuté au sommet de l'architecture.Le développement de pilotes de périphériques dédiés au noyau Linux a été nécessaire car les API exécutés sur Linux ne peuvent pas accéder directement à des IP matérielles (propriétés intellectuelles) données. Les pilotes de périphériques dédiés et la bibliothèque SystemC TLM PwClkARCH ont été utilisés pour mettre en œuvre la gestion de l'énergie de l'architecture afin d'optimiser la consommation énergétique globale de l'architecture lorsqu'une API blockchain donnée est exécutée. Ce travail propose également différentes API de blockchain (Ethereum, Hyperledger Sawtooth) écrites en C++, incluant toutes les exigences de la blockchain donnée, par exemple, l'encodage ABI, la structure de transaction et les primitives cryptographiques. Les résultats de la contribution montrent qu'une réduction significative de la consommation énergétique globale peut être obtenue lorsque l'opération de multiplication des points de la courbe elliptique est accélérée par le matériel. Les résultats montrent également que lorsque la taille de la charge utile de la transaction augmente, il est intéressant d'utiliser des accélérateurs matériels de hachage pour réduire la consommation d'énergie globale et accélérer l'exécution de l'API donnéeNowadays, numerous IoT applications have become an essential part of people's lives, industries, and modern ecosystems. Most IoT applications are based on a centralized system in which all of the system participants have to rely on a central entity. In such a system, data immutability, data traceability, and transparency cannot be provided. Blockchain technology is an entirely decentralized system in which the third trusted party (central entity) is removed. The particularity of this technology is that it provides that once data is deployed on it, it cannot be modified or removed from the system. Contrarily to centralized systems, blockchain provides data traceability and transparency. Most modern blockchains also allow the deployment of smart contracts, which are digital programs that can be read by all participants and executed automatically according to an event on the blockchain. The advantageous features of blockchain technology show a clear interest in the integration of IoT with blockchain technology.This thesis contribution studies the integration possibilities of IoT with blockchain technology. One of the main parts of the contributions is developing a model of dedicated low-power-consumption IoT hardware architecture that enables communication with multiple types of blockchains. The architecture model is composed of an ARM-based CPU emulated on QEMU and cryptographic hardware accelerator designs modeled in SystemC TLM high-level hardware description language. A Linux Operating System (OS) is executed on top of the architecture.The development of dedicated Linux Kernel device drivers was required because the AIPs executed on Linux can not directly access given hardware IPs (Intellectual Properties). Dedicated device drivers and PwClkARCH SystemC TLM library were used to implement the architecture's power management to optimize the architecture's overall energy consumption when a given blockchain API is executed. This work also proposes different blockchain APIs (Ethereum, Hyperledger Sawtooth) written in C++, including all the requirements of the given blockchain, e.g., ABI encoding, transaction structure, and cryptographic primitives. The contribution results represent that a significant reduction of the overall energy consumption can be achieved when the elliptic curve point multiplication operation is hardware accelerated. The results also show that when the payload size of the transaction increases, it is worth using hash hardware accelerators to decrease the overall energy consumption and accelerate the given API's execution

IoT industry is growing at a rapid pace since everyone wants to connect everything to internet in order to use various services and applications using shared data. Openness is observed as an emerging trend in IoT industry. Security & privacy of the data are very important aspects in the design and deployment of the connected devices or Internet of Things. Fast growth in number of connected devices, heterogeneity, constrained resources, privacy, software upgrades and operational environment create important security related challenges in this domain. It is difficult to address challenges even with the considerable amount of existing work that has been done for decades in the area of security & privacy. In this research, a semi-systematic literature survey of the state of the art is conducted related to security & privacy aspects within the IoT area. The results were validated by conducting qualitative survey with IoT practitioners. The efforts have resulted towards identifying several security trends & challenges and security design aspects that can be considered by IoT practitioners in order to design an open and secure IoT system.It can be concluded from the study that security is not only needed but is a mandatory characteristic for IoT. However, there are no general guidelines that can be proposed to address security issues since security is not only a technical problem but is more of an awareness, mindset, people and process issue. In this thesis, a novel model is proposed with openness and security characteristics. This model is grounded based on the theoretical findings and empirical data obtained from IoT practitioners. Each of the characteristics has its own design aspects that needs to be considered by IoT practitioners to design a more secure IoT system.

This thesis details the design of a protocol translator between the industrial-automation protocol OPC UA, and HTTP. The design is based on the architecture of the protocol translator of the Arrowhead framework, and is interoperable with all of its associated protocols. The design requirements are defined to comply with a service-oriented architecture (SOA) and RESTful interaction through HTTP, with minimal requirement of the consuming client to be familiar with OPC UA semantics. Effort is put into making translation as transparent as possible, but limits the scope of this work to exclude a complete semantic translation. The solution presented in this thesis satisfies structural- and foundational interoperability, and bridges interaction to be independent of OPC UA services. The resulting translator is capable of accessing the content of any OPC UA server with simple HTTP-requests, where addressing is oriented around OPC UA nodes.

The Internet of Things (IoT) has seen a huge growth spurt in the last few years which has resulted in the need for more standardised IoT technology. Because of this, numerous IoT platforms have sprung up that offer a variety of features and use different technologies which may not necessarily be compliant with each other or with other technologies. Companies that wish to enter theIoT market are in constant need to find the most suitable IoT platform for their business and have a certain set of requirements that need to be fulfilled by the IoT platforms in order for the application to be fully functional. The problem that this thesis project is trying to address is a standardised procedure for selecting the IoT platforms. The project aims to suggest a list of requirements derived from the available IoT architecture models, that must be followed by IoT applications in general, and a subset of these requirements may be specified by the companies as essentials for their application. This thesis project also aims at development of a Web platform to automate this process, by listing the requirements on this website and allowing companies to input their choices,and accordingly show them the list of IoT platforms that comply with their input requirements. A simple Weighted Sum Model is used to rank the search result in order to prioritise the IoT platforms in order of the features that they provide. This thesis project also infers the best IoT architectural model available based on a comparative study of three major IoT architectures with respect to the requirements proposed. Hence the project concludes that this Web platform will ease the process of searching for the right IoT platform andthe companies can therefore make an informed decision about the kind of IoT platform that they should use, thereby reducing their time spent on market research and hence their time-to-market.

The enterprise systems are built with a monolithic way of software architecture which may not be the very suitable and realistic solutions, due to the quantity and diversity of Internet of Things (IOT) devices connected to the internet. The large code is based as a single deployable unit; making it cumbersome and difficult to change, test, and deploy – typically in the monthly deployment cycles. Which could potentially be a large impact and high-risk for updates and deployment build up between releases. The thesis aims to exploit Microservices Architecture in context of the Internet of Things. Because of scalability and rapid deployment, Microservices Architecture (MSA) naturally fits for M2M and IOT developments. Therefore, it has become increasingly popular and highly suited as a design choice in the context of developing IOT applications. We have proposed various ontologies for conceptual architecture designs. Our conceptual model encompasses all the essential elements and entities that constitute IOT; describing various characteristics of microservices and consideration to be used as a basis for developing a Reference Architecture model. The reference architecture is effectively exploiting Microservices Architectural Style for a diverse set of things composition like sensor devices, connectivity and transportation protocols for IP enabled IOT smart objects. The thesis will contribute to the conceptual space of more successful reference architectures. The goal is to provide features and deployment information with instantiation guidelines to derive the software architecture instances in a given IOT application domain. Thus, it promises to become a valuable framework in the derivation of the Microservices IOT architectures.

The Internet of things refers to the set of objects that have identities and virtual personalities operating in smart spaces using intelligent interfaces to connect and communicate within social environments and user context. Interconnected devices communicating to each other or to other machines on the network have increased the number of services. The concepts of discovery, brokerage, selection and reliability are important in dynamic environments. These concepts have emerged as an important field distinguished from conventional distributed computing by its focus on large-scale resource sharing, delivery and innovative applications. The usage of Internet of Things technology across different service provisioning environments has increased the challenges associated with service selection and discovery. Although a set of terms can be used to express requirements for the desired service, a more detailed and specific user interface would make it easy for the users to express their requirements using high-level constructs. In order to address the challenge of service selection and discovery, we developed an architecture that enables a representation of user preferences and manipulates relevant descriptions of available services. To ensure that the key components of the architecture work, algorithms (content-based and collaborative filtering) derived from the architecture were proposed. The architecture was tested by selecting services using content-based as well as collaborative algorithms. The performances of the algorithms were evaluated using response time. Their effectiveness was evaluated using recall and precision. The results showed that the content-based recommender system is more effective than the collaborative filtering recommender system. Furthermore, the results showed that the content-based technique is more time-efficient than the collaborative filtering technique.

Mestrado em Engenharia de Computadores e TelemáticaAs plataformas IoT (Internet das Coisas) existentes hoje em dia permitem que diversos dispositivos (“coisas”) com uma fraca capacidade de processamento, como sensores, estejam ligados à rede pública que é a Internet. São colhidos e partilhados dados do meio ambiente que nos rodeia permitindonos conhecer melhor o nosso mundo, agir de forma mais informada e garantir a funcionalidade de certos equipamentos. No entanto, atualmente, os dados são armazenados em claro nas plataformas IoT e podem ser acedidos na sua íntegra por terceiros causando diversos problemas de segurança como a falta de privacidade dos donos dos dados que não conseguem ter qualquer controlo sobre os seus dados produzidos. Como tal, é aqui apresentada uma modificação da arquitetura típica de uma plataforma IoT com o objetivo de adicionar a desejada segurança sobre os dados. Foram adicionadas entidades externas confiáveis de forma a que se conseguisse distribuir as chaves, os dados cifrados e a identificação do utilizador. Desta forma nenhuma entidade, por si só, terá o poder de pôr em causa a privacidade dos utilizadores. A entidade de processamento tem o papel de transformar dados criando anonimato. A entidade de certificação tem o papel de certificar código que irá efetuar essa transformação recorrendo a análise humana. A entidade de autorização tem o papel de permitir que o utilizador possa autorizar ou não todo este processo de acesso e obtenção dos seus dados por parte de terceiros.
The IoT (Internet of Things) platforms existing today allow multiple devices (“things”) with a low processing capacity, such as sensors, to be connected with the public network that is the Internet. Environmental data from our surrounding is collected and shared allowing us to better understand our world, act in a more informed manner, perform real-time monitoring of humans and ensure the functionality of certain equipment. However, currently, the data is stored in clear text in the IoT platforms and can be fully accessed by third parties causing many security problems as the lack of privacy of the owners of the data that cannot have any control over their production. As such, a modification of the typical IoT platforms architecture is presented here in order to add the desired security to the data. External trusted entities were added so that elements could be distributed such as the keys, the encrypted data and user identification. Thus, no entity alone has the power to undermine the privacy of users. The processing entity has the role of transforming data creating anonymity. The certification entity has the role of certifying the code that will make this transformation using human analysis. The authorization entity has the role of allowing the user to authorize or not all of this process of access and retrieval of their data by third parties.

Internet of Things (IoT) and Machine Type Communication (MTC) have got more momentum in the last few years but still, need to be penetrated with their full swing in our daily life. This can be possible with general framework that provides global network coverage. Non-terrestrial networks comprised of satellites and aerial platforms are expected to provide next-generation communication services in underserved and un-served areas by ensuring the quality of service that cannot be covered by existing terrestrial networks owing to economical and geographical limitations. The aim of this thesis is to formulate a set of massive and critical MTC use cases such as global environment monitoring, tracking of shipping containers and smart agriculture, and assess their comprehensive requirements like data size, sensor node density and uplink capacity and discuss possible network architectures and deployments focusing on satellite or aerial networks. A rigorous discussion on different network architectures to address the requirements have been presented, that involve (1) Low Earth Orbit (LEO) satellite based network, (2) High Altitude Platform (HAP) based network, and (3) HAP and UAV based network. The proposed network architectures have been simulated and analyzed using MATLAB tools for respective use cases in terms of required number of satellites or aerial platforms. The criteria for selection of network architectures for the use cases are based on the minimum number of satellites or aerial platforms. The results show that LEO constellation consisting of 260 satellites are feasible concerning deployment and management for global environment monitoring network. Similarly, 1440 LEO satellites provide global coverage for tracking of shipping containers. Smart agriculture use case requires high throughput, and hence HAP and UAV integrated network architecture is more realistic for a fully autonomous system as compared to other network architectures. Cooperative control and management of set of agricultural machines can be performed at the UAV. Simulation results show that single UAV can be capable of commanding and controlling the agricultural smart machines in one square kilometer crop field and can send the summary of events to the central station via a HAP.Internet of Things (IoT) och maskintypkommunikation (MTC) har fått mer fart under de senaste åren men måste fortfarande penetreras med sin fulla sväng i vårt dagliga liv. Detta kan vara möjligt med allmän ramverk som ger global nätverkstäckning. Icke- markbundna nät bestående av satelliter och flygplattformar förväntas tillhandahålla nästa generations kommunikationstjänster i undervärdiga och obetjänade områden genom att säkerställa kvaliteten påtjänster som inte kan täckas av befintliga marknät pågrund av ekonomiska och geografiska begränsningar. Syftet med den här avhandlingen är att formulera en uppsättning massiva och kritiska MTC-användningsfall som global miljöövervakning, spårning av fraktcontainrar och smart jordbruk, och utvärdera deras omfattande krav som datastorlek, sensornoddensitet och upplänkkapacitet och diskutera möjliga nätverk arkitekturer och distributioner med fokus påsatellit- eller flygnät. En rigorös diskussion om olika nätverksarkitekturer för att möta kraven har presenterats, som involverar (1) Low Earth Orbit (LEO) satellitbaserat nätverk, (2) High Altitude Platform (HAP) baserat nätverk, och (3) HAP och UAV baserat nätverk. De föreslagna nätverksarkitekturerna har simulerats och analyserats med MATLAB-verktyg för respek- tive användningsfall i termer av det nödvändiga antalet satelliter eller flygplattformar. Kriterierna för val av nätverksarkitekturer för användningsfallen är baserade pådet minsta antalet satelliter eller flygplattformar. Resultaten visar att LEO-konstellationen bestående av 260 satelliter är möjlig när det gäller distribution och hantering för globalt miljöövervakningsnätverk. Påliknande sätt ger 1440 LEO-satelliter global täckning för spårning av fraktcontainrar. Småjordbruksanvändningsfall kräver hög kapacitet, och följaktligen är HAP och UAV integrerad nätverksarkitektur mer realistisk för ett helt autonomt system jämfört med andra nätverksarkitekturer. Kooperativ kontroll och hantering av jordbruksmaskiner kan utföras vid UAV. Simuleringsresultat visar att en enda UAV kan vara kapabel att kommandera och kontrollera jordbrukssmarta maskiner i ett kvadratkilometer grödningsfält och kan skicka sammanfattningen av händelser till centralstationen via HAP.

L'Internet des Objets (IdO) et les Environnements Intelligents (EI) ont attiré beaucoup d'activités de recherche et développement au cours de la dernière décennie. Pourtant, de nombreuses applications IdO/EI d'aujourd'hui sont encore limitées à l'acquisition et au traitement des données de capteurs et de leur contexte, avec un contrôle, le cas échéant, utilisant soit des solutions de base ou demandant l'intervention humaine, loin du contrôle automatique qui est un facteur essentiel de promouvoir ces technologies. Cette thèse vise à apporter le savoir-faire de la théorie du contrôle et des systèmes réactifs dans le domaine IdO/EI pour arriver à une solution avec une méthode formelle pour l'aspect de contrôle qui fait défaut. Nous proposons l'extension d'un canevas logiciel pour une infrastructure générique et partagée IdO/EI qui offre des interfaces de haut niveau pour réduire l'effort de conception, et qui permet l'auto-configuration et l'adaptation des applications de contrôle sur des propriétés génériques de l'environnement sans intervention humaine en utilisant les connaissances générales sur le domaine qui s'appliquent à chaque instance cible de système IdO/EI. Dans cette infrastructure étendue, les entités physiques individuelles (y compris toutes les "choses", appareils électriques et sous-ensembles de l'espace) peuvent être regroupées comme des entités virtuelles par des propriétés communes afin de fournir un niveau d'abstraction plus élevé pour le contrôle et d'autres applications, ainsi qu'une meilleure adaptation aux changements des configurations au niveau inférieur. Sur le requis d'une solution générique et commun dénominateur partagée par toutes les applications de l'IdO/EI dans un environnement donné, nous proposons pour cette infrastructure, de modéliser les entités cibles supervisées et contrôlées, y compris les entités individuelles et de leurs regroupements, ainsi que les choses et les entités spatiales, par des automates à états finis, pour être en mesure d'appliquer la technique de la synthèse des contrôleur discrets (SCD) aux différents niveaux d'abstraction et de granularité. SCD est une méthode formelle qui construit automatiquement un contrôleur, s'il existe, en assurant les objectifs de contrôle exigés concernant le modèle de comportement du système donné en termes d'automates parallèles synchrones. Les langages de programmation BZR et les outils Sigali existants sont utilisés pour effectuer la SCD et de générer un contrôleur de manière automatique. Les modules logiciels nécessaires sont proposés dans l'implémentation tels que le module de maintenance de relation qui garde une association correcte entre les instances d'entités individuelles et les groupes, et répercute des commandes d'action du contrôle de haut niveau aux actionneurs correspondants. Ce module est destiné à évoluer plus tard vers une solution plus générique comme une base de données graphes comprenant à la fois la base de connaissances générales et relations spécifiques d'instance environnement. La résolution des conflits entre les objectifs de contrôle venant de contrôleurs concurrent est également indispensable en raison des objectifs de l'ouverture de la plateforme. Un simulateur de contexte basé sur Java a été développé pour simuler l'environnement de la maison au sein de plusieurs scénarios proposés pour la validation, tels que le contrôle de la charge électrique et l'adaptation au contexte de l'activitéThe Internet of Things (IoT) and Smart Environments (SE) have attracted a lot of research and development activities during the last decade. Yet many present-day IoT/SE applications are still limited to the acquisition and processing of sensor data and its context, with control, if any, using either basic solutions or requiring human intervention, far away from the automatic control which is an essential factor to promote the technologies. This thesis targets to bring knowhow from control theory and reactive systems to the IoT/SE domain to achieve a solution with a formal method for the missing control aspect. We propose the extension of a framework in order to build a shared generic IoT/SE infrastructure offering high-level interfaces to reduce design effort, and enabling the self-configuration and adaptation of control applications over generic properties of the environment without human interaction by using general knowledge over the domain that applies to each target instance of IoT/SE system. In this extended framework, individual physical entities (including all relevant "things", appliances and subsets of space) may be grouped as virtual entities by shared properties to provide a higher level abstraction for control and other applications and better adaptation to lower level configuration changes. Requiring a generic common denominator solution shared by all IoT/SE applications in a given environment, we propose for this infrastructure, to model by finite state automata the target entities to be monitored and controlled, including both individual entities and their groupings, as well as things and space entities, to be able to apply discrete controller synthesis (DCS) technique over any of these at different levels of abstraction and granularity. DCS is a formal method which constructs automatically a controller, if it exists, guaranteeing the required control objectives regarding to the given system behavior model in terms of synchronous parallel automata. The existing BZR programming language and Sigali tools are employed to perform DCS and generate a controller in an automatic way. Necessary supporting software modules are proposed in the implementation such as the relation maintenance module keeping the correct association between individual entity instances and groups, and dispatching the action orders from the high level control to corresponding actuators. This module would evolve later to a more generic solution such as a graph data base including both the general knowledge base and specific environment instance relations. Conflict resolution between objectives of control coming from concurrent controllers is also indispensable due to the intended openness of the platform. A java based context simulator has been developed to simulate the home environment within several scenarios proposed for the validation, such as electrical load control and activity context adaptation

La sociedad está siendo testigo de una revolución digital que ha generado cambios en diversos ámbitos, entre los cuales se encuentra la construcción o transformación de edificios comunes a Smart Buildings (SB), lo que puede conseguir que varios aspectos como la seguridad, el consumo energético, entre otros, se gestionen con mayor eficiencia. El desarrollo de SBs es acompañado del desarrollo de las tecnologías IoT (Internet of Things), las cuales son una opción de soporte para convertir un edificio en inteligente.
Sin embargo, la implementación de SBs está sujeta a varios riesgos que no se han cubierto en conjunto, destacando tres de ellos que son la incapacidad de escalar el SB para que se adapte a nuevos requisitos (escalabilidad), que los dispositivos IoT (sensores y actuadores) no sean compatibles entre ellos (incompatibilidad), y que la transmisión de datos en el sistema sea vulnerada por agentes maliciosos (seguridad en la transmisión de datos).
Siendo así, el presente proyecto propone una arquitectura tecnológica para las implementaciones de SBs con IoT que brinde a las organizaciones un diseño guía que les permita cambiar sus componentes según la complejidad y exigencia de sus requerimientos, y que solucione en conjunto los tres riesgos previamente mencionados. Finalmente, el resultado del proyecto es una arquitectura tecnológica para las implementaciones de SBs validada en el cumplimiento de los requisitos planteados.Society is witnessing a digital revolution that has generated changes in various areas, among which is the construction or transformation of common buildings to Smart Buildings (SB), which can achieve that various aspects such as security, energy consumption, among other things, are managed more efficiently. The development of SBs is accompanied by the development of IoT (Internet of Things) technologies, which can support the transformation of a regular building into an SB. However, the implementation of SBs is subject to several risks that have not been covered together, highlighting three of them which are the inability to scale the SB to adapt to new requirements (scalability), that IoT devices (sensors and actuators) are not compatible with each other (incompatibility), and that the data transmission inside the system is compromised by malicious agents (security in data transmission). Thus, this project proposes a technological architecture for the implementations of SBs with IoT that provides organizations with a guiding design that allows them to change their components according to the complexity and demand of their requirements, and that jointly solves the three previously mentioned risks. Finally, the result of the project is a technological architecture for the implementations of SBs validated in the fulfillment of the raised requirements.

With industry expectations of billions of Internet-connected things, commonly referred to as the IoT, we see a growing demand for high-performance on-chip bus architectures with the following attributes: small scale, low energy, high security, and highly configurable structures for integration, verification, and performance estimation.
Our research thus mainly focuses on addressing these key problems and finding the balance among all these requirements that often work against each other. First of all, we proposed a low-cost and low-power System-on-Chips (SoCs) architecture (IBUS) that can frame data transfers differently. The IBUS protocol provides two novel transfer modes – the block and state modes, and is also backward compatible with the conventional linear mode. In order to evaluate the bus performance automatically and accurately, we also proposed an evaluation methodology based on the standard circuit design flow. Experimental results show that the IBUS based design uses the least hardware resource and reduces energy consumption to a half of an AMBA Advanced High-Performance Bus (AHB) and Advanced eXensible Interface (AXI). Additionally, the valid bandwidth of the IBUS based design is 2.3 and 1.6 times, respectively, compared with the AHB and AXI based implementations.
As IoT advances, privacy and security issues become top tier concerns in addition to the high performance requirement of embedded chips. To leverage limited resources for tiny size chips and overhead cost for complex security mechanisms, we further proposed an advanced IBUS architecture to provide a structural support for the block-based AES algorithm. Our results show that the IBUS based AES-encrypted design costs less in terms of hardware resource and dynamic energy (60.2%), and achieves higher throughput (x1.6) compared with AXI.
Effectively dealing with the automation in design and verification for mixed-signal integrated circuits is a critical problem, particularly when the bus architecture is new. Therefore, we further proposed a configurable and synthesizable IBUS design methodology. The flexible structure, together with bus wrappers, direct memory access (DMA), AES engine, memory controller, several mixed-signal verification intellectual properties (VIPs), and bus performance models (BPMs), forms the basic for integrated circuit design, allowing engineers to integrate application-specific modules and other peripherals to create complex SoCs.

Expensive and complex automated systems for greenhouses are frequently utilized in the horticulture industry. In parallel, smart systems for home automation has recently seen a rapid increase in popularity. This project aims to combine the climate optimization capabilities of industrial systems with the convenience of home automation systems. More specifically, this project is focused on the design and implementation of electrical and mechanical requirements of a smart greenhouse system. This involved the selection of hardware components, such as sensors, actuators and controllers. It also involved the interconnection between these components and the development of measurement and control systems to autonomously manage the greenhouse. The system is based on a WiFi-connected microcontroller. Parameters monitored include; temperature, humidity and wind-speed. Irrigation is controlled by a solenoid valve and can be scheduled to desired intervals. Ventilation and temperature optimization is done by controlling the roof-hatch with a linear actuator and control of a heater. The results demonstrate a accurate and reliable system with low power consumption. The resulting prototype can be installed in new and existing greenhouses. Functionalities can be remotely controlled and monitored by the convenience of an android application. The total cost of the components used was around 4 500 SEK. Further development could be done to enable seamless scalability with additional components and functionalities. Climate optimization by incorporation of weather forecast as a parameter could be implemented to further reduce energy consumption.Dyra och komplexa automatiserade växthussystem är vanligt förekommande inom industrin för hortikultur. Parallellt har populariteten för "Smart Home" system för hemautomatisering radikalt ökat. Målet med detta projekt är att kombinera klimatoptimiseringsmöjligheterna hos industriella system med lättanvändligheten hos system för hemautomatisering. Detta projekt fokuserar specifikt på designen och implementationen av de elektriska och mekaniska krav som ställs på ett "smart greenhouse system". Detta innefattar; val av komponenter såsom sensorer, aktuatorer samt styrenhet men även sammankopplingen mellan dessa komponenter och utvecklingen av mjukvara till reglersystemet, som i sin tur syftar till automatiseringen i växthuset. Systemet är baserat på en WiFi-uppkopplad mikrokontroller. Parametrar som monitoreras är; temperatur, luftfuktighet och vindhastighet. Bevattning kontrolleras av en magnetventil och kan schemaläggas för bevattning i önskade intervall. Ventilering och temperaturoptimisering sker genom kontroll av taklucka med hjälp av ett linjärt ställdon samt kontroll av ett värmeelement. Resultatet demonstrerar ett pålitligt och punktligt system med låg energiförbrukning. Prototypen som utvecklats kan installeras i både nya och befintliga växthus. Funktionaliteterna kan smidigt fjärrkontrolleras och monitoreras från en android applikation. Den totala kostnaden för de komponenter som använts var runt 4500 kr. Vidareutveckling vad gäller skalbarhet för att sömlöst lägga till komponenter och funktionaliteter bör övervägas. För ytterligare minskad energiförbrukning med hjälp av klimatoptimering kan väderprognos adderas som en parameter.

Dans cette thèse, nous proposons une méthodologie basée sur les modèles pour gérer la complexité de la conception des systèmes autonomiques cognitifs intégrant des objets connectés. Cette méthodologie englobe un ensemble de patrons de conception dont nous avons défini pour modéliser la coordination dynamique des processus autonomiques pour gérer l’évolution des besoins du système, et pour enrichir les systèmes avec des propriétés cognitives qui permettent de comprendre les données et de générer des nouvelles connaissances. De plus, pour gérer les problèmes reliés à la gestion des big data et à la scalabilité du système lors du déploiement des processus, nous proposons une plate-forme sémantique supportant le traitement des grandes quantités de données afin d’intégrer des sources de données distribuées et hétérogènes déployées sur le cloud pour générer des connaissances qui seront exposées en tant que service (KaaS). Comme application de nos contributions, nous proposons un système cognitif prescriptif pour la gestion du plan de traitement du patient. Ainsi, nous élaborons des modèles ontologiques décrivant les capteurs et le contexte du patient, ainsi que la connaissance médicale pour la prise de décision. Le système proposé est évalué de point de vue clinique en collaborant avec des experts médicaux, et de point de vue performance en proposant des différentes configurations dans le KaaSIn this thesis, we propose a collaborative model driven methodology for designing Autonomic Cognitive IoT systems to deal with IoT design complexity. We defined within this methodology a set of autonomic cognitive design patterns that aim at (1) delineating the dynamic coordination of the autonomic processes to deal with the system's context changeability and requirements evolution at run-time, and (2) adding cognitive abilities to IoT systems to understand big data and generate new insights. To address challenges related to big data and scalability, we propose a generic semantic big data platform that aims at integrating heterogeneous distributed data sources deployed on the cloud and generating knowledge that will be exposed as a service (Knowledge as a Service--KaaS). As an application of the proposed contributions, we instantiated and combined a set of patterns for the development of prescriptive cognitive system for the patient treatment management. Thus, we elaborated two ontological models describing the wearable devices and the patient context as well as the medical knowledge for decision-making. The proposed system is evaluated from the clinical prescriptive through collaborating with medical experts, and from the performance perspective through deploying the system within the KaaS following different configurations

Between 4000-10 000 ads each day every day. That is how many ads we as customers are exposed to individually, each and every day. To reach a higher efficiency in marketing, marketing managers and store owners nowadays aiming to increase the customer satisfaction by striving to understand the customer behavior and their decisioning-making. For the aim of this thesis, we investigated if coloring cues in the retail environment had an impact on customers’ behavior in a specific retail store environment. This experiment was taken place in a small town within Sweden, named Karlstad. The retail store belongs to the electronic sector and the participants included in the experiment were randomly visiting customers of this electronical retail store. In the experiment we used IoT devices from Texas Instruments, a sensor device, called CC2650, enabled us to collect data from interactions by customers and products. In our experiment we compared three periods of data with the help from the analysis method of one-way ANOVA. The result was showing that there is a significant variance between at least two of our three periods of measurements, and by the results of this thesis we could reject the Null Hypothesis (H0). As the H0, were telling that there would not be any differences between any of the three measured periods of time. Further, with insights from our one-way ANOVA, we could determine with help from a complementary analysis method, the Tukey’s HSD, we could point out which periods that were significant different from one another. This made us come into conclusions that there is a possibility to predict the customer behavior and the customer’s Need for Touch (NFT), a part of the nudging theory, and can give the marketing managers and store owners in retail an increase of understanding of the customer’s behavior. Future research could look into how customer’s behavior can change within different type of retail stores, and also if coloring cues in retail stores within bigger cities will have another impact on customer’s behavior.

L’Internet des objets (IdO) utilise l’interconnexion de milliards de petits appareils informatiques, appelés «Objets», pour fournir un accès à des services et à des informations partout dans le monde. Cependant, la suite de protocoles IP a été conçue il y a plusieurs décennies dans un but totalement différent, et les fonctionnalités de l’IoT soulignent désormais les limites de l’IP. En parallèle aux efforts d’adaptation de l’IP à l’IdO, des architectures alternatives basées sur les réseaux orientés information promettent de satisfaire nativement les applications Internet émergentes. L’une de ces architectures est appelée réseau de données nommées (NDN). Nos objectifs à travers le travail rapporté dans ce manuscrit peuvent êtrerésumés en deux aspects. Le premier objectif est de montrer que NDN est adapté à la prise en charge des systèmes IdO. Le deuxième objectif est la conception de deux solutions de communication légères pour les réseaux sans fil contraints avec NDNThe Internet of Things (IoT) uses the interconnection of billions of small computing devices, called “Things”, to provide access to services and information all over the world. However, the IP protocol suite has been designed decades ago for a completely different purpose, and IoT features now highlight the limitations of IP. While adapting IP for the IoT might be seen as cutting corners, alternative architectures based on the Information Centric Networking (ICN) paradigm promise to natively satisfy emerging Internet applications. One of these architectures is Named Data Networking (NDN). Our objectives through the work reported in this manuscript can be summarized in two aspects. The first objective is to show that NDN is suitable to support IoT networking. The second objective is the design of two solutions for lightweight forwarding in constrained wireless networks

El presente proyecto profesional tiene como meta mostrar la posibilidad de poder automatizar y optimizar el proceso de Recolección, Transporte y Disposición Final de Residuos Peligrosos de PETRAMAS mediante la implementación de IoT (Internet of Things). En la actualidad, en el campo de la tecnología de información se han desarrollado diversos servicios y dispositivos que permiten automatizar procesos que hasta hace un par de años no era factible. Es en este escenario, que se busca la utilización de una solución Web basada en IoT que pueda ser utilizada por los operadores de la organización con la finalidad de poder gestionar los contenedores de residuos y utilizar los datos para generar información relevante para la mejora del proceso.
Para lograr el desarrollo del proyecto se han generado diferentes etapas que han permitido realizar un levantamiento de información y generar una propuesta de solución para la organización.
En primer lugar, mediante el framework de Zachman se puede conocer la arquitectura empresarial de PETRAMAS que a su vez ayuda a identificar los procesos críticos, definición de objetivos e indicadores que permitirán conocer la aplicación de las mejoras a implementar.
En segundo lugar, se tuvo que trabajar sobre un marco teórico que ayuda a entender las herramientas, framework, teorías, etc., que brindan sustento conceptual de lo que se busca como objetivo del proyecto.
En tercer lugar, se aplicaron conocimientos de ingeniería para poder hacer un levantamiento de requerimientos e identificar los requisitos del sistema que permiten darle forma y fundamento a las decisiones de diseño, drivers, tácticas y estilos de arquitectura tomadas.
Finalmente, para llevar una adecuada gestión de proyectos, se ha seguido la guía de buenas prácticas del PMBOK en su sexta Edición. Esta guía permite visualizar el avance que ha tenido el proyecto y deja en evidencia los pasos a seguir para la implementación del mismo.The aim of this professional project is to show, through the implementation of the Internet of Things, the possibility of being able to automate and optimize the process of Collection, Transport and Final Disposal of Hazardous Waste in PETRAMAS. At present, in the field of information technology, various services and devices have been developed that cause automation to be generated at various levels, allowing data to be captured in real time that was not taken into account until now. In this case, the use of a solution on the Web is sought that can be used by the operators of the organization in order to be able to manage the waste containers and use the data to generate relevant information for the improvement of the process. To achieve the development of the project, different stages have been generated that have made it possible to collect information and generate a solution proposal for the organization. In the first place, through the Zachman framework, it is possible to know the PETRAMAS business architecture, which in turn helps to identify critical processes, definition of objectives and indicators that will allow knowing the application of the improvements to be implemented. Second, it was necessary to work on a theoretical framework that helps to understand the tools, frameworks, theories, etc., that provide conceptual support for what is sought as the objective of the project. Third, engineering knowledge was applied to be able to make a requirements survey and identify the system requirements that allow giving shape and foundation to the design decisions, drivers, tactics and architectural styles taken. Finally, in order to carry out adequate project management, the PMBOK good practice guide in its sixth Edition has been followed. This guide allows you to visualize the progress that the project has had and highlights the steps to follow for its implementation.

Avec l'évolution exponentielle de l'Internet des Objets (IoT), assurer la sécurité des réseaux est devenue un grand défi pour les administrateurs réseaux. La sécurité des réseaux est basée sur de multiples équipements indépendants tels que Firewall, IDS/IPS, NAC dont le rôle principal est de contrôler les informations échangées entre le réseau de l'entreprise et l'extérieur. Or, l'administration de ces équipements peut s'avérer très complexe et fastidieuse si elle est réalisée manuellement, équipement après équipement. L'introduction du concept de Software Defined Networking (SDN) depuis ces dernières années, et du protocole OpenFlow, offre beaucoup d'opportunités pour l'amélioration de la sécurité des réseaux en proposant une administration centralisée et programmable.Dans le cadre de cette thèse, nous avons proposé une nouvelle approche de sécurisation des échanges dans un réseau en fonction des événements détectés et de manière automatisée. Cette solution basée sur l'approche SDN couplé avec un système de détection d'intrusion permet d’analyser, de détecter et de supprimer des menaces de sécurité dans un réseau et de manière automatisée. En implémentant cette solution, nous contribuons à faire évoluer la manière de sécuriser les échanges dans un réseau avec du SDN couplé avec un IDS à travers la mise en place d'une architecture réelle de cas d'usage. Ainsi, la gestion de la sécurité du réseau devient simplifiée, dynamique et évolutiveWith the exponential evolution of the Internet of Things (IoT), ensure the network security has become a big challenge for networkadministrators. Traditionally, the network security is based on multiple independent devices such as firewall, IDS/IPS, NAC where the main role is to monitor the information exchanged between the inside and the outside perimeters of the enterprises networks. However, the administration of these network devices can be complex and tedious with an independent manual configuration. Recently, with the introduction of the Software Defined Networking concept (SDN) and the OpenFlow protocol offers many opportunities by providing a centralized and programmable network administration.As part of this research work, we proposed a new approach to secure the network traffic flows exchanges based on a method of events detection, in an automated manner. This solution is based on the SDN approach coupled to an intrusion detection system which allows analyze, detect and remove security threats. With the implementation, we contribute to change the paradigm of secure the network traffic flows exchanges using the SDN principle, coupled with an IDS in a real use case architecture. In this way, the management of network security becomes simplified, dynamic and scalable

In the last decade, major developments in mobile and sensor network technologies, as well as in more secure data management solutions allowed an accelerated expansion of the Internet of Things (IoT) in different markets, including the smart lighting technology. These technological developments, currently shaping the lighting industry, have the power to enhance the liveability of spaces and improve people’s lives. However, in this thesis it is highlighted how such technological evolution is often marked by an engineering character over a design approach. In particular, this thesis focuses on smart lighting technology applied in urban environments and how the integration of information technology into the physical realm can enhance space quality and empower citizens’ participation. The main body is divided into two sections: The first part provides an overview of the technological solutions that are currently being implemented in the lighting design field. The second part advances a schematic projection of future trends, starting from the analysis of what is being developed in other related disciplines, such as urban planning and visual arts. Both parts are literature-based. The final section features the opinion of noteworthy lighting professionals about possible real-life applications of smart lighting technology. Since this thesis has been written during the Covid-19 pandemic, the author decided to include speculations regarding how this event might influence the future of urban lighting.

Attacks against mobile systems have escalated over the past decade. There have been increases of fraud, platform attacks, and malware. The Internet of Things (IoT) offers a new attack vector for Cybercriminals. M2M contributes to the growing number of devices that use wireless systems for Internet connection. As new applications and platforms are created, old vulnerabilities are transferred to next-generation systems. There is a research gap that exists between the current approaches for security framework development and the understanding of how these new technologies are different and how they are similar. This gap exists because system designers, security architects, and users are not fully aware of security risks and how next-generation devices can jeopardize safety and personal privacy. Current techniques, for developing security requirements, do not adequately consider the use of new technologies, and this weakens countermeasure implementations. These techniques rely on security frameworks for requirements development. These frameworks lack a method for identifying next generation security concerns and processes for comparing, contrasting and evaluating non-human device security protections. This research presents a solution for this problem by offering a novel security framework that is focused on the study of the “functions and capabilities” of M2M devices and improves the systems development life cycle for the overall IoT ecosystem.

Le déploiement massif des objets connectés, formant l'Internet des Objets ou IoT, bouleverse aujourd'hui les environnements réseaux traditionnels. Ces objets, auparavant exempts de connectivité, sont désormais susceptibles d'introduire des vulnérabilités supplémentaires dans les environnements qui les intègrent. La littérature dresse aujourd'hui un portrait peu flatteur de la sécurité de ces objets, qui constituent de plus en plus des cibles de choix pour les attaquants, qui y voient de nouvelles surfaces exploitables pour s'introduire dans les environnements auparavant sécurisés. En outre, les moyens de communications non-filaires utilisés par ces objets sont nombreux, avec des caractéristiques très hétérogènes à tous les niveaux protocolaires, notamment en terme de fréquences utilisées, qui rendent complexes l'analyse et la surveillance des environnements qui s'en équipent. Ces problématiques, et notamment l'hétérogénéité forte de ces nombreux protocoles, remettent en question les solutions traditionnelles permettant d'assurer la sécurité des échanges effectués. Or, l'explosion du nombre de ces objets impose d'adapter ou de proposer des architectures de sécurité qui soient adaptées à ces nouvelles problématiques. Dans cette thèse, nous nous intéressons à la surveillance et à la détection d'anomalies pouvant survenir sur les moyens de communications sans-fil utilisés dans l'IoT, quels qu'ils soient. Nous avons relevé un manque crucial de solutions ayant la capacité d'analyser tous les échanges, et ce, qu'importe le protocole utilisé. Pour y répondre, nous proposons une architecture de sécurité basée sur le monitoring des signaux radios physiques, permettant de s'affranchir de la connaissance des protocoles et donc d'être générique. Son objectif est d'apprendre le modèle des comportements radios légitimes d'un environnement à l'aide de sondes radios, puis d'identifier les déviations vis-à-vis de ce modèle, pouvant correspondre à des anomalies ou des attaques. La description de cette architecture est la première contribution de cette thèse. Nous avons ensuite étudié l'applicabilité de notre solution dans différents contextes, chacun ayant ses caractéristiques propres. La première étude, correspondant à notre deuxième contribution, consiste à proposer une implémentation et un déploiement de notre approche dans les domiciles connectés. L'évaluation de celle-ci face à des attaques réelles injectées dans l'espace radio et ses résultats montrent la pertinence de notre approche dans ces environnements. [...]The massive deployment of connected objects, forming the Internet of Things (IoT), is now disrupting traditional network environments. These objects, previously connectivity-free, are now likely to introduce additional vulnerabilities into the environments that integrate them. The literature today paints an unflattering picture of the security of these objects, which are increasingly becoming prime targets for attackers who see them as new exploitable surfaces to penetrate previously secure environments. In addition, the wireless means of communication used by these objects are numerous, with very heterogeneous characteristics at all protocol levels. Particularly in terms of the frequencies used, which make it difficult to analyse and monitor the environments that are equipped with them. These issues, and in particular the strong heterogeneity of these numerous protocols, call into question the traditional solutions used to ensure the security of the exchanges carried out. However, the explosion in the number of these objects requires security architectures that are adapted to these new issues. In this thesis, we are interested in monitoring and detecting anomalies that may occur in any wireless means of communication used in the IoT. We found a critical lack of solutions with the ability to analyze all exchanges, regardless of the protocol used. To answer this question, we propose a new security architecture based on the monitoring of physical radio signals, making it possible to free oneself from protocol knowledge and therefore to be generic. Its objective is to learn the model of legitimate radio behaviour in an environment using radio probes, then to identify deviations from this model, which may correspond to anomalies or attacks. The description of this architecture is the first contribution of this thesis. We then studied the applicability of our solution in different contexts, each with its own characteristics. The first study, corresponding to our second contribution, consists in proposing an implementation and deployment of our approach in connected homes. The evaluation of the latter in the face of real attacks injected into radio space and its results show the relevance of our approach in these environments. Finally, the last contribution studies the adaptation and deployment of our generic solution to professional environments where the presence of expert users promotes the integration of advanced diagnostic information to identify the origins of an anomaly. The subsequent evaluation and the results associated with each of the diagnostic mechanisms implemented demonstrate the value of our approach in heterogeneous environments

The work in this thesis proposes a number of energy efficient architectures of IoT networks. These proposed architectures are edge computing, Passive Optical Network (PON) and Peer to Peer (P2P) based architectures. A framework was introduced for virtualising edge computing assisted IoT. Two mixed integer linear programming (MILP) models and heuristics were developed to minimise the power consumption and to maximise the number of served IoT processing tasks. Further consideration was also given to the limited IoT processing capabilities and hence the potential of processing task blockage. Two placement scenarios were studied revealing that the optimal distribution of cloudlets achieved 38% power saving compared to placing the cloudlet in the gateway while gateway placement can save up to 47% of the power compared to the optimal placement but blocked 50% of the total IoT object requests. The thesis also investigated the impact of PON deployment on the energy efficiency of IoT networks. A MILP model and a heuristic were developed to optimally minimise the power consumption of the proposed network. The results of this investigation showed that packing most of the VMs in OLT at a low traffic reduction percentage and placing them in relays at high traffic reduction rate saved power Also, the results revealed that utilising energy efficient PONs and serving heterogeneous VMs can save up to 19% of the total power. Finally, the thesis investigated a peer-to-peer (P2P) based architecture for IoT networks with fairness and incentives. It considered three VM placement scenarios and developed MILP models and heuristics to maximise the number of processing tasks served by VMs and to minimise the total power consumption of the proposed network. The results showed that the highest service rate was achieved by the hybrid scenario which consumes the highest amount of power compared to other scenarios.

A novel, interactive Android app has been developed that monitors the health of type 2 diabetic patients in real-time, providing patients and their physicians with real-time feedback on all relevant parameters of diabetes. The app includes modules for recording carbohydrate intake and blood glucose; for reminding patients about the need to take medications on schedule; and for tracking physical activity, using movement data via Bluetooth from a pair of wearable insole devices. Two machine learning models were developed to detect seven physical activities: sitting, standing, walking, running, stair ascent, stair descent and use of elliptical trainers. The SVM and decision tree models produced an average accuracy of 85% for these seven activities. The decision tree model is implemented in an app that classifies human activity in real-time.

Récemment, l'intégration entre les environnements informatiques et de réseautage a été largement promu pour fournir des services intelligents à des utilisateurs finaux ainsi que l'utilisation efficace des ressources. Cette convergence a ouvert la voie à l'émergence de l'internet des objets (IdO). Le paradigme de l'IdO repose principalement sur la fabrication d'objets, appelés les choses, disparaître et se tissent dans le tissu de notre vie de tous les jours pour nous soutenir dans l'accomplissement des activités quotidiennes. L'évolutivité et l'hétérogénéité sont parmi les principaux défis qui entravent la réalisation à grande échelle de services de l'IdO dans la vie quotidienne des utilisateurs. Afin de relever les défis de l'IdO, un nouveau volet de recherche est venu en avant dans la littérature comme une classe paradigmatique des Cyber-physiques systèmes sociaux (CSPR), qui est connu comme l'Internet social des choses (Siot). Le SIOT se fonde sur la notion soulignée par phénomène petite-monde où la structure sociale permettant relation sociale fondée sur la confiance entre les personnes et les objets, d'une manière qui ressemble à des services de réseaux sociaux traditionnels (SNS) est suggérée de relever les défis de l'IdO. Cependant, depuis SIOT hérite des caractéristiques de différents informatiques et de réseautage environnements (par exemple, l'IdO et SNS) cela, en fait, augmente la quantité et la variété des données contextuelles qui doit être manipulé pour Adaptive fourniture de services dans Siot, qui agit comme le principal défi adressé dans cette thèse. Autrement dit, dans cette thèse, nous proposons la notion de contexte cognitif lorsque, dans certaine situation spatio-temporelle, le raisonnement sur les aspects objectifs du cadre, ce qui représente l'environnement physique, avec le contexte subjective, qui représente les aspects comportementaux et sociaux, est considéré comme l'amélioration des services SIOT intelligence et la capacité d'adaptation aux besoins conjoncturels des utilisateurs. Nous envisageons technologies du Web sémantique pour déployer notre contexte cognitif proposé dans deux domaines d'application; sensible au contexte recommandation des tâches quotidiennes dans les maisons intelligentes et structure sociale dépendant de la situation des choses. Un prototype de preuve de concept a été développé pour chaque domaine d'application, dans le but de démontrer l'intégration harmonieuse des objets sur le Web pour la réalisation de certaines applications. Nos résultats empiriques montrent un niveau de service amélioré l'adaptabilité et la complexité en temps de fonctionner lors de l'application de notre contexte cognitif suggéréThe paradigm of the Social Internet of Things (SIoT) is being promoted in the literature to boost a new trend wherein the benefits of social network services are exhibited within the network of connected objects i.e., the Internet of Things (IoT). The novel user-friendly interaction framework of the SIoT opens the doors for enhancing the intelligence required to stimulate a shift in the IoT from a heterogeneous network of independently connected objects towards a manageable network of everything. In practice, achieving scalability within the large-scale and the heterogeneous paradigm of the IoT while maintaining on top of its user-friendly and intuitive services to bridge human-to-machine perceptions and encourage the technology’s adaptation is a major challenge which is hindering the realization and deployment of the IoT technologies and applications into people’s daily live. For the goal of handling IoT challenges, as well as improve the level of smart services adaptability to users’ situational needs, in this thesis, novel SIoT-based application architecture is provided. That is, Semantic Web Technologies are envisaged as a means to develop automated, value-added services for SIoT. While, interoperability and automation are essential requirement to seamlessly integrate such services into user life, Ontologies are used to semantically describe Web services with the aim of enabling the automatic invocation and composition of these services as well as support interactions across the cyber, physical and social worlds. On the other hand, handling the variety of contextual data in SIoT for intelligent decision making is another big challenge which is still in very early stages of research. In this thesis we propose a cognitive reasoning approach taking into consideration achieving situational-awareness (SA) in SIoT. This reasoning approach is deployed within two application domains where results show an improved level of services adaptability compared to location-aware services which are previously proposed in the literature

Nowadays, the concept of Internet of Things has revolutionized the industry, making possible the existence of billions of devices worldwide that constantly produce vast amounts of data. This valuable information may only be processed and filtered by complex applications that will eventually sell the information as products. As a consequence, protection of this data and secure, authorized access turn out to be key priorities in this field. A study about authentication protocols has been carried out, according to certain security factors, giving as outcome that OpenID Connect might be the best solution to the problem. Therefore, an authentication / authorisation module has been developed for an IoT platform to protect its data. Evaluations made for the module stated that the protocol and its implementation assure enough levels of security. Nonetheless, accounting features and a better user privacy management are still open issues that avoid full protection of data in an open technology as the Internet.

With the advent of the Internet-of-Things way more sensor-generated data streams came available that researchers want to exploit context from. Many researchers worked on context recognition for rather unimodal data in pervasive systems, but recent works about object virtualisation in the Internet-of-Things domain enable context-exploitation based on processing multi-modal information collected from pervasive systems. Additionally to the sensed data there is formalised knowledge about the real world objects emitted by IoT services as contributed by the author in [1], [2] and [3]. In this work an approach for context recognition is proposed that takes knowledge about virtual objects and its relationships into account in order to improve context recognition. The approach will only recognise context that has been predefined manually beforehand, no new context information can be exploited with the work proposed here. This work’s scope is about recognising the activity that a user is most likely involved in by observing the evolving context of a user of a pervasive system. As an assumption for this work the activities have to be modelled as graphs in which the nodes are situations observable by a pervasive system. The pervasive system to be utilised has to be built compliant to the Architectural Reference Model for the IoT (ARM) to which the author has contributed to in [4] and [5]. The hybrid context model proposed in this thesis is made of an ontology-based part as well as a probability-based part. Ontologies assist in adapting the probability distributions for the Hidden Markov Model-based recognition technique according to the current context. It could be demonstrated in this work that the context-aware adaptation of the recognition model increased the detection rate of the activity recognition system.

Con la crescita in complessità delle infrastrutture IT e la pervasività
degli scenari di Internet of Things (IoT) emerge il bisogno
di nuovi modelli computazionali basati su entità autonome capaci di portare a termine obiettivi
di alto livello interagendo tra loro grazie al supporto di infrastrutture come il Fog Computing,
per la vicinanza alle sorgenti dei dati, e del Cloud Computing per offrire servizi
analitici complessi di back-end in grado di fornire risultati per milioni di utenti.
Questi nuovi scenarii portano a ripensare il modo in cui il software viene progettato
e sviluppato in una prospettiva agile. Le attività dei team di sviluppatori (Dev)
dovrebbero essere strettamente legate alle attività dei team che supportano
il Cloud (Ops) secondo nuove metodologie oggi note come DevOps.
Tuttavia, data la mancanza di astrazioni adeguata a livello di linguaggio di programmazione,
gli sviluppatori IoT sono spesso indotti a seguire approcci di sviluppo bottom-up che spesso
risulta non adeguato ad affrontare la compessità delle applicazione del settore e
l'eterogeneità dei compomenti software che le formano.
Poichè le applicazioni monolitiche del passato appaiono difficilmente scalabili
e gestibili in un ambiente Cloud con molteplici utenti,
molti ritengono necessaria l'adozione di un nuovo stile architetturale,
in cui un'applicazione dovrebbe essere vista come una composizione di micro-servizi,
ciascuno dedicato a uno specifica funzionalità applicativa e ciascuno sotto la
responsabilità di un piccolo team di sviluppatori, dall'analisi del problema
al deployment e al management.
Poichè al momento non si è ancora giunti a una definizione univoca
e condivisa dei microservices e di altri concetti che emergono da IoT e dal Cloud,
nè tantomento alla definzione di linguaggi sepcializzati per questo settore,
la definzione di metamodelli
custom associati alla produzione automatica del software di raccordo con
le infrastrutture potrebbe aiutare un team di sviluppo ad elevare il livello di
astrazione, incapsulando in una software factory aziendale i dettagli implementativi.
Grazie a sistemi di produzione del sofware basati sul Model Driven Software Development (MDSD),
l'approccio top-down attualmente carente può essere recuperato, permettendo
di focalizzare l'attenzione sulla business logic delle applicazioni.
Nella tesi viene
mostrato un esempio di questo possibile approccio, partendo dall'idea che
un'applicazione IoT sia in primo luogo un sistema software distribuito in cui
l'interazione tra componenti attivi (modellati come attori)
gioca un ruolo fondamentale.

Human body is a complex system organized at different levels such as cells, tissues and organs, which contributes to 11 important organ systems. The functional efficiency of this complex system is evaluated as health. Traditional healthcare is unable to accommodate everyone's need due to the ever-increasing population and medical costs. With advancements in technology and medical research, traditional healthcare applications are shaping into smart healthcare solutions. Smart healthcare helps in continuously monitoring our body parameters, which helps in keeping people health-aware. It provides the ability for remote assistance, which helps in utilizing the available resources to maximum potential. The backbone of smart healthcare solutions is Internet of Things (IoT) which increases the computing capacity of the real-world components by using cloud-based solutions. The basic elements of these IoT based smart healthcare solutions are called "things." Things are simple sensors or actuators, which have the capacity to wirelessly connect with each other and to the internet. The research for this dissertation aims in developing architectures for these things, focusing on IoT-based smart healthcare solutions. The core for this dissertation is to contribute to the research in smart healthcare by identifying applications which can be monitored remotely. For this, application-specific thing architectures were proposed based on monitoring a specific body parameter; monitoring physical health for family and friends; and optimizing the power budget of IoT body sensor network using human body communications. The experimental results show promising scope towards improving the quality of life, through needle-less and cost-effective smart healthcare solutions.
