Although interest in connected devices has surged in recent years, barriers still remain in realizing the dream of the Internet of Things (IoT). The main challenge in delivering IoT systems stems from a huge diversity in their demands and constraints. Some applications work with small sensors and operate using minimal energy and bandwidth. Others use high-data-rate multimedia and virtual reality systems, which require multiple-gigabits-per-second throughput and substantial computing power. While both extremes stress the computation, communications, and energy resources available to the underlying devices, each intrinsically requires different solutions to satisfy its needs. This thesis addresses both bandwidth and energy constraints by developing custom software-hardware systems. To tackle the bandwidth constraint, this thesis introduces three systems. First, it presents AirShare, a synchronized abstraction to the physical layer, which enables the direct implementation of diverse kinds of distributed protocols for loT sensors. This capability results in a much higher throughput in today's IoT networks. Then, it presents Agile-Link and MoVR, new millimeter wave devices and protocols which address two main problems that prevent the adoption of millimeter wave frequencies in today's networks: signal blockage and beam alignment. Lastly, this thesis shows how these systems enable new IoT applications, such as untethered high-quality virtual reality. To tackle the energy constraint, this thesis introduces a VLSI chip, which is capable of performing a million-point Fourier transform in real-time, while consuming 40 times less power than prior fast Fourier transforms. Then, it presents Caraoke, a small, low-cost and low-power sensor, which harvests its energy from solar and enables new smart city applications, such as traffic management and smart parking.

Повний текст джерелаIn this thesis, we deal with security challenges in the Internet of Things. The evolution of the Internet toward an Internet of Things created new challenges relating to the way to secure communications given the new constraints of IoT, namely: resource constrained objects, heterogeneity of network components, the huge size of the network, etc. Indeed, the Internet evolved from a network of computers and servers toward a huge network connecting billions of smart communicating objects. These objects will be integrated into complex systems and use sensors and actuators to observe and interact with their physical environment. The security requirements of the interactions between smart objects depend on the context which evolves in time and space. Consequently, the definition of the security policies should be adaptive and context-aware. In this thesis, we were interested in the problem of access control in IoT relying on Attribute based Encryption (ABE). Indeed, ABE schemes present many advantages in implementing a cryptographic fine-grained access control. However, these schemes raise many implementation challenges because of their complexity and high computation and energy overheads. To overcome this challenge, we leveraged the heterogeneity of IoT to develop collaborative and distributed versions of ABE schemes. Our solutions reduce remarkably the overhead in terms of energy consumption and computation. The second limitation of ABE schemes is the absence of efficient attribute/key revocation techniques. We have proposed batch based mechanisms for attribute/key revocation in CP-ABE. We demonstrated the efficiency of the proposed solutions through simulations. Finally, we have proposed a CP-ABE based solution for the problem of grouping proof. This problem consists of providing the proof that a set of objects are present simultaneously (same time and same location). The propose solution has many applications such as enforcing the security of NFC based payments and the access to sensitive locations
Shaikh, Yasir Saleem. "Privacy preserving internet of things recommender systems for smart cities." Electronic Thesis or Diss., Institut polytechnique de Paris, 2020. http://www.theses.fr/2020IPPAS001.
Повний текст джерелаDuring the past decade, the Internet of Things (IoT) technology has revolutionized almost all the fields of daily life and has boosted smart cities. Smart cities use IoT technology to collect various types of sensors’ data and then use such data to offer a variety of applications. Since the smart cities’ applications are used by the citizens, therefore providing the customized recommendation services to the citizens based on their preferences, locations and profiles, as well as by exploiting the IoT data (e.g., traffic congestion and parking occupancy) is of great importance which could be provided by an IoT recommender. However, since the IoT recommender utilizes the private data of citizens (e.g., profiles, preferences and habits), it breaches the privacy of the users because the IoT recommender could track the routines and habits of the users by analyzing the historical database or by analyzing the regular recommendation services it offers. Therefore, it is important to preserve the privacy of the users from the IoT recommender. In this thesis, we propose a novel privacy preserving IoT recommender system for smart cities that provides recommendations by exploiting the IoT data of sensors and by considering various metrics. Our approach is organized in three parts. Firstly, we develop an EU General Data Protection Regulation (GDPR)-compliant IoT recommender system for smart parking system that provides recommendations of parking spots and routes by exploiting the data of parking and traffic sensors. For this, we first propose an approach for the mapping of traffic sensors with route coordinates in order to analyze the traffic conditions (e.g., the level of congestion) on the roadways and then developed an IoT recommender. The IoT recommender has been integrated into the smart parking use case of an H2020 EU-KR WISE-IoT project and has been evaluated by the citizens of Santander, Spain through a prototype. Additionally, we develop an IoT recommender for smart skiing that provides skiing routes comprised of specific types of slopes, as well as the nearest slope. For skiing routes, there does not exist any stable routing engine. Therefore, a novel routing engine for skiing routes was developed. This work has also been integrated into the smart skiing use case of WISE-IoT project. Secondly, although the developed IoT recommender for smart parking is GDPR-compliant, however, it does not fully protect the privacy of users. Because, an indiscriminately sharing of users’ data with untrusted third-party IoT parking recommender system causes a breach of privacy, as user’s behavior and mobility patterns can be inferred by analyzing the past travelling history of users. Therefore, we preserve privacy of users against parking recommender system while analyzing their past parking history using k-anonymity and differential privacy techniques. Lastly, since the smart cities applications are developed in a vertical manner and do not talk/communicate with each other, i.e., each application is developed for a certain scenario which generally does not share data with other smart cities applications. Therefore, we proposed two frameworks for the recommendation services across smart cities applications using social IoT. Firstly, on how social IoT can be used for the recommendation services across smart cities applications, and secondly, we propose another type of communication of social IoT at a global level, i.e., social cross-domain application-to-application communications, that enables smart cities applications to communicate with each other and establish social relationships between them

One of the fundamental challenges in Internet-of-Things systems is that network environment is always changing. Conventional networking approaches do not consider the dynamic evaluation of the networks or consider the network dynamic as a mirror thing, which may not be able to work or has a low efficiency in the Internet-of-Things systems. This dissertation is uniquely built by considering the dynamic network environment and even taking advantage of the network dynamic to improve the network performances, with a focus on the routing and offloading issues. The first part is related to the routing design in the opportunistic mobile networks. The opportunistic mobile network is expected to be an intrinsic part of the Internet of Things. Devices communicate with each other autonomously without any centralized control and collaborate to gather, share, and forward information in a multi-hop manner. The main challenge in opportunistic mobile networks is due to intermittent connection and thus data is delivered through store-carry-forwarding paradigm. In this dissertation, We found an observation regarding the contact duration and proposed efficient data partitioning routing algorithms in the opportunistic mobile networks. The second part is related to the offloading issues in the Internet-of-things systems. With the surging demand on high-quality mobile services at any time, from anywhere, how to accommodate the explosive growth of traffics with/without existing network infrastructures is a fundamental issue. Specifically, We consider three different offloading problems, i.e., cellular data offloading, cloud task offloading, and mobile worker task offloading problems in vehicular networks, cloud, and crowdsourcing platforms. The common issue behind them is how to efficiently utilize the network resources in different scenarios by design efficient scheduling mechanisms. For the cellular data offloading, We explored the trade-off of cellular offloading in the vehicular network. For the cloud task offloading, We conducted the research to adjust the offloading strategies wisely so that the total offloading cost is minimized. For the worker task offloading in the smart cities, We optimized the cost-efficiency of the crowdsourcing platforms.

Повний текст джерелаThe term "Internet of Things" refers to when an object from the real world becomes a part of the internet. Tunabyggen in Borlänge plans to implement an information system that will monitor temperature and humidity in selected facilities using a constant internet connection and different sensors. It is a simple system that doesn't seem to have a major impact on the current operations. The economic effects is often possible to calculate in advance, but the impact on staff, environment and routines may be forgotten. We have with this thesis examined the initial effects that may occur after the implementation of a new information system with Internet of Things functionality in a business, within the categories of economy, working environment, environmental impact and system management. To answer this we made a case study which is based on a scenario methodology that consists of four phases. Phase 1, where we got our case and created an understanding of the scenario field. Phase 2, identifying the key factors. It has been done through a literature study and interviews with relevant staff on Tunabyggen. Phase 3, where the analysis of these key factors were made through the situation and future analysis. Phase 4, where we generate scenarios of the analyzed key factors. Finally we have done a SWOT analysis to highlight the strengths, weaknesses, opportunities and threats. The results clearly show signs that there will be many effects for Tunabyggen after the implementation of the new information system, which manifests itself in all categories. The conclusion is that even the implementation of a menial information system like this one, the impacts are many. This is something that we believe should be considered by all companies that are thinking of acquiring a new system so they do not only evaluate IT-systems in economic terms, but also other factors that play a crucial role for the implementation of an information system to be successful.

Повний текст джерелаThe Internet of Things (IoT) is a large and rapidly expanding area with regards to both hardware platforms and software. When it comes to hardware platforms for the IoT some are more powerful and able to run a traditional OS like Linux, while other platforms are too constraint to do so. To ease the development within the IoT area an appropriate IoT OS is needed for these constrained hardware platforms, which can handle most of the functionality a traditional OS offer.Therefore, we evaluate IoT OSs targeted for low performance battery powered devices. In this thesis Contiki, mbed, RIOT and Zephyr are evaluated. The aim of this evaluation is to determine important IoT OS characteristics for resource constrained devices, and to highlight difficulties and experiences related to the building process of prototypes for such IoT devices.The evaluation of the IoT OSs were conducted on four types of data with regards to several measurable OS characteristics according to a criteria based evaluation method.The evaluation resulted in a list of six IoT OS characteristics important for wireless, resource constrained and battery powered devices. Furthermore the evaluation highlights potential setbacks during the building process of a prototype system for such devices and it also explains what experiences that can be gained.The conclusion of this thesis contributes with experience related to IoT OS prototype construction and also an evaluation result with respect to the six IoT OS characteristics for constraint battery driven devices.

Повний текст джерелаIn recent years, Internet of Things-devices have experienced explosive growth, and the possibilities are endless for how manufacturers can increase our quality of life through Internet-connected objects. Thus, Internet of Things devices in various forms have found their place in the homes and lives of many people. Even greater will the the development opportunities be as the 5G network will be implemented in our society in the near future. 5G is expected to contribute, in comparison with 4G, very fast data transferspeeds and new technologies. The purpose of Internet of Things-devices is to somehow increase the quality of life of users, but as they are also simple targets for attacks, they risk rather deteriorating it for individuals. In fact, the number of malware attacks is constantly increasing, especially against Internet of Things-devices. As 5G contributes new technologies that allow devices to have a direct interconnected communication and connection to the Internet, it raises the question of whether it has an impact on individuals' information security.This study includes a systematic literature review on security risks for individuals with Internet of Things-devices in 5G networks. The study's findings suggest that Internet ofThings-devices in 5G networks together create a dangerous environment for individuals from an information security perspective. The study's findings provide an overview of six security risks with Internet of Things-devices in 5G networks, seventeen vulnerabilities that include security risks, their consequences and whether the security risks and vulnerabilities involve risk factors against individuals' confidentiality, integrityor accessibility.

Повний текст джерелаA technology change towards the Internet of Things (IoT) can lead to changes for both businesses and consumers in the form of changing work roles, new ways of producing content and new ways to share content. The focus of this report has been on what this means for technical writers. To highlight this problem, an investigation has been conducted at a case company specializing in producing technical documentation and which has begun to look closer at IoT. The investigation led to the conclusion that the role of technical writer within an IoT-context looks different from a technical writer who writes traditionally. To write technical documentation for IoT, higher demands are placed on technical competence in the form of basic programming skills and object-oriented thinking.

The number of people and things connected to the Internet continue growing at an exponential rate. This record setting growth along with the reduction in small sensor costs and machine learning enabled a concept called the Internet of Things (IoT) to thrive. With numerous applications in both commercial and government spaces, the IoT has the ability to transform any organizations network capabilities. The Air Force has a unique set of requirements centered on cyberspace superiority and the ability to command and control people and things. This paper leverages the traditional systems engineering "'V" model as a framework to develop and analyze a concept for an Air Force command and control network. Methods and tools such as stakeholder analysis, hierarchical control structures and object-process diagrams are used to develop the concept of operations, system architecture, and the preliminary design. The programs technology readiness is also assessed before outlining key milestones and deliverables required for transitioning the program forward in the acquisition life-cycle.

Internet of Things (IoT) is being touted as the next wave of big opportunity. However, the picture does not seem to be very rosy for semiconductor vendors and chip suppliers who might find it difficult to make high revenues or gain a position of power to drive this market. There are several reasons for this: i. The IoT devices are made up of relatively less complex, low cost and low profit-margin chip components such as sensors, RF and microcontrollers ii. The IoT is not a single market, but an umbrella of fragmented markets with many different niche segments and lack of common standards, making it difficult for companies to decide what they are going to do and which segments and opportunities they want to focus iii. High value and importance is given to software and services in the IoT ecosystem iv. The steadily shifting of power from companies in the supply chain to service providers v. The continuing rising cost of semiconductor manufacturing vi. Increasing SoC design landscape, rather than discreet components Most of the semiconductor companies are not realizing this and, thus, they don't have a go-to-market strategy for IoT in place, even after making a decision to enter the market. The thesis aims at identifying the major IoT trends that will determine the prospects for semiconductor companies. In addition, it tries to answer the questions regarding how and where they can add value to this market and, in return, create a sustainable competitive advantage, or maximum ROI, for themselves. In more details, the thesis will address some of the secondary questions as follows: i. Why having a IoT strategy is so important for semiconductor companies? ii. Who are the different players in the IoT ecosystem? iii. How is evolution of hardware capabilities, as well as other technologies including software and firmware, happened and happening in the IoT space? iv. In the tough economic situations, how can semiconductor manufacturing companies capture more value?

Повний текст джерелаSammanfattning Syfte: Detta arbete behandlar Internet of Things eller IoT inom drift och underhåll i förvaltningsskedet. IoT handlar bl.a. om “smarta” byggnadskomponenter som kan meddela när de går sönder samt att man kan styra dessa på avstånd. Det finns många tidigare undersökningar kring hur man kan använda IoT i byggnader men inte särskilt många undersökningar på hur detta kan användas inom just drift och underhållsarbetet med fastigheter. Därför är målet med detta arbete att utreda möjligheterna till användning av Internet of Things inom drift och underhåll i förvaltningsskedet. Som i sin tur bryts ner i frågeställningarna: (1) Vilka användningsområden finns det för Internet of Things inom fastighetsförvaltning, avseende drift och underhåll? (2) Vilka besparingar i form av arbetstid skulle man kunna åstadkomma genom att tillämpa Internet of Things inom fastighetsförvaltning, avseende drift och underhåll? (3) Hur ser inställningen ut för tillämpning av Internet of Things i förvaltningsbranschen? Metod: Huvudstrategin för detta arbete är en Fallstudie på Fastighetsavdelningen, Jönköpings kommun. Tillvägagångssättet består av intervjuer med IoT-konsulter och med anställda på fastighetsavdelningen, dokumentanalys av enhetstider för olika arbetsuppgifter för drifttekniker i Jönköpings kommun samt litteraturstudie. Resultat: Den första frågeställningen besvaras att det mesta är möjligt med IoT då det finns en enorm mängd olika sensorer och det produceras ständigt nya sensortyper. Man kan även skräddarsy IoT-lösningar vilket bidrar till flexibiliteten i systemen. Det som sätter gränser för IoT i dagsläget är ekonomin samt att hitta värde i insamlade data. Frågeställning två visar att besparingsmöjligheter finns. Beräkningar är baserade på attityder hos respondenterna och vad de anser är rimliga besparingspotential. Detta resulterar i en besparing på ca 13 000 arbetstimmar/år av 30 000 arbetstimmar/år vilket är lika med 40 %. Den tredje frågeställningen ger resultatet att inställningen för att implementera IoT till arbetsuppgifter är överlag positiv hos både anställda på fastighetsavdelningen och IoT-konsulter. Av de olika yrkeskategorierna är det intressant att nämna att störst intresse ligger hos förvaltare och underhållsingenjörer och minst hos drifttekniker. Konsekvenser: Slutsatser dras att IoT kan effektivisera arbetet med drift och underhåll i förvaltningsskedet. Man kan komma att spara in mycket arbetstid genom att använda IoT. Eftersom intresse finns hos avdelningen borde man undersöka vidare vilka kostnader systemet kan komma att kosta om man skulle börja utrusta fastigheterna med sensorer etc. Vid en eventuell implementering kan Jönköpings kommun bli en förebild för andra förvaltare och hamna i framkant i teknikutvecklingen. Begränsningar: Avgränsningarna i detta arbete är kostnader för IoT-produkter och hur systemen i detalj är uppbyggda. De arbetsuppgifter som undersöks i detta arbete är tillsynsuppgifter.

Smart, connected devices are becoming an integral part of our lives, bridging the communication between human-to-machine and machine-to-machine interactions. The potential socioeconomic impact of the Internet of Things (loT) in the Industrials space is forecasted to be huge. These connected devices will result in a significant increase in the overall complexity of systems. While the rate of loT adoption by Industrials is on the rise, a lot of uncertainty remains with regards to the readiness of organizations and the impact of adoption. This could be due to lack of vision from leadership, lack of resources, and also lack of capabilities required for successful adoption. The goal of this thesis is to enable organizations to position themselves well for Industrial loT adoption. This thesis analyzes the current state of Industrial loT adoption by viewing Industrial organizations adopting loT as complex systems. The research consists of an analysis and synthesis of quantitative and qualitative data from organizations around the world, of existing theory, of recent industry research along with the application of systems thinking techniques. The outcome of the thesis is a framework for successful Industrial loT adoption. The research findings reveal several significant implications for managers and leaders of Industrial organizations and the need to employ systems thinking for understanding Industrial loT organizations.

This thesis provides an analysis of privacy and security controls for internet-connected data-driven systems, known as the Internet of Things (IoT). The grounding theory is that numerous pre-existing privacy and security control methods -- not necessarily crafted for IoT -- will bear on the future of IoT privacy and security. This thesis covers fifteen case studies across six different control categories: Individual Choice, Command and Control Regulations, Operational Standards, Technical Standards, Compliance Frameworks, and Federal Authorities. These case studies reveal major deficiencies in current IoT privacy and security controls. IoT privacy and security controls lack a domain or contextual-use focus. Further, most current controls also fail to specify the risks or harms they intend to resolve. Therefore, the current IoT privacy and security controls induce a significant privacy and security market failure. This market failure is evident in recent IoT privacy and security events such as the Federal Trade Commission's cases against the IoT system developers TRENDnet and D-Link. I define three necessary paradigm shifts needed to improve IoT privacy and security controls. I also recommend a specific research endeavor to develop domain-, risk-, and harms-centric privacy and security standards. The realization of these paradigm shifts, and the products from this research endeavor, will navigate the IoT ecosystem towards more effective privacy and security control.

Повний текст джерелаGatlyktor är oftast tända under alla timmar då det är mörkt ute, även fast det inte är något fordon eller annat objekt som använder vägen. Istället för att slösa energi på att ha gatlyktorna tända när det inte är några fordon som använder vägen, bör gatlyktorna vara tända när fordon är i närheten av dem och släckta annars. Ett distribuerat nätverk kan användas för att hantera kommunikationen mellan gatlyktor till att dela information om fordon i närheten. Det finns gatlyktsystem som anpassar efter miljön och hanterar kommunikationen, men är inte optimerat för landsvägar med låg trafik. Därför är distribuerad kommunikation för gatlyktsystem implementerat genom att låta gatlyktorna vara en del av ett distribuerat system. Varje gatlykta är representerad med en Zolertia RE-Mote, en sensor för detektering av objekt och en LED. Representationen är trådlöst kopplat som ett meshnätverk där de kan kommunicera med varandra och skicka vidare datapaket till noder längre bort i nätverket. Konceptet att ha gatlyktorna i ett distribuerat system tros fungera och kan tänkas att appliceras på gatlyktor på landsvägar för att spara energi.

Internet of Things(IoT) is a collection of interconnected devices which collects data from its surrounding environment. The data collected from these devices enable emerging technologies like smart home and smart cities, where objects are controlled remotely. With the increase in the number of such devices, there is a demand for self-powered devices to conserve electrical energy. Energy harvesters are suitable for this purpose because they convert ambient energy into electrical energy to be stored in an energy buffer, which is to be used when required by the device. Using energy harvesters as power supply presents us with two scenarios. First, when there is sufficient ambient energy, the surplus energy, which is the energy harvested beyond the storage capacity of the buffer, is not consumed by the device and thus, wasted. Second, when the harvested energy is scarce, the device is forced to shutdown due to lack of power. In this thesis, we consider the overall security of an energy harvested IoT device in both energy scenarios. We optimize cryptographic algorithms to utilize the surplus energy and design a secure protocol to protect the device when the energy is scarce. Utilizing both the ideas together provides adequate security to the Internet of Things.

Aging is an increasingly disruptive force in the US -- nearly 1 in 5 Americans will be at least 65 years old by 2030. Largely due to the high incidence of chronic disease among older adults, health care spending is larger in magnitude for older adults than it is for any other age group. To treat older adults and reduce the prevalence of chronic disease more effectively and efficiently, health professionals may likely incorporate patient-generated health data (PGHD) from the Internet of Things (IoT). IoT devices can help providers to evaluate treatment options, compliance, and overall patient well-being. Critics of PGHD integration in the health care space cite challenges such as poor interoperability of devices and electronic health record systems, a lack of standards, a host of liability concerns, workflow interruptions, and a lack of reimbursement models. There is little research, however, that explores how the inclusion and analysis of PGHD may affect provider empathy and the physician-patient relationship. We were interested in understanding how the integration of wearables, smart devices, and other connected health devices would affect the physician-patient (or provider-patient) relationship and how those changes might affect both providers and patient health and well-being. We conducted two surveys, one of health care providers and one of patients, to understand current and expected uses of connected health devices to examine how the collection and analysis of PGHD will affect provider empathy and the physician-patient relationship. We subsequently examine across different age groups, how the provision of health care and individual health management is projected to change as a result of PGHD analysis. Finally, we evaluate the socio-technical barriers to connected health devices and discuss the entities which could successfully mitigate these barriers, as perceived by health care providers and patients.
