Abstract:

Networks will soon connect a wide range of computing devices within the home. Amongst those devices will be home entertainment devices. Remote control over the network will be a key application for networked entertainment devices, and requires a protocol for communication understood by both controller and controlled device. Devices capable of communication using multiple control protocols will be compatible with a wider range of controllers than those which implement only one control protocol. This work examines home networks and a number of control protocols. The implementations of the UPnP and AV/C protocols for an AV receiver are described. The issues involved in the concurrent use of multiple control protocols to control a device are considered, possible methods of concurrent control discussed, and a solution which simulates virtual copies of the device is implemented and tested.

Abstract:

Networked Appliances (NAs) is a new research field and it comes under the concept of home networking. The SIP (Session Initiation Protocol) and Agent-based NA system proposed in the thesis aims to build a smart system that provides the capability of autonomous and asynchronous control and management of NAs from both inside and outside of a home network. The SIP technology makes the NAs system well adapted for communications over the Internet; and the leading-edge agent technology presents a new approach to empower users with advanced information processing methods and reduce the workload of users. In the proposed system, various agents cooperate with each other to fulfill different tasks on behalf of homeowners. The system architecture and features are presented and a prototype model is implemented. The performance of the system is discussed to verify and validate the system design.

Abstract:

With AMS comes great possibilities for increased energy efficiency, but to achieve its full potential, the end users must be provided with the necessary means of monitoring and controlling their consumption. This thesis describes the process of developing a web application prototype meant to serve such a purpose. It explains the various architectural and technological decisions that support the prototype, and it elaborates on how data from the users’ smart meters can be synthesized with price information to help users see the economic effect of their current consumption pattern. A working prototype has been developed and security- and performance tests have been carried out to mitigate bottlenecks and prevent security breaches. Observations during the pilot project have shown promising trends and it is hoped that this thesis will inspire further innovation in the field of smart energy solutions.

Abstract:

Domestic space and place, as well as how we conceptualise the home, are shifting in response to changes in digital and SNS technologies, and our relationships with such technologies. The home is not only the building in which we live, but a networked assemblage of material and digitally mediated space and place. This study examines predominantly white middle class arrangements of domestic space and place in South Africa, which provides insight into a relatively unexplored aspect of digital culture: the performance of domesticity via SNS, particularly Facebook. Furthermore gendered and racialised power dynamics and privilege in everyday life were investigated through a digital ethnography and critical discourse analysis of posts by 50 Facebook users. This data was supplemented by interviews and in-situ observations of five couples drawn from the broader sample. In combination, these methods revealed how space, place, and domestic responsibilities are secured through narrative practice. Through this study I show how Facebook has emerged as a collaborative platform where storytelling practices are influenced by the site architecture and algorithm. Facebook has opened up the private space of the home allowing domestic space, place, and practice to steadily gain visibility. This visibility, analysed in conjunction with Actor-Network Theory, revealed that homes, and narratives about the homes, are networked and dependent on relationships between actants. The home, and the relationships that stabilise it, are also reflective of discourses and power relations. Human actors negotiated territory and network roles, and these negotiations reveal power and hierarchy. Women remain more tightly bound to the home because of cultural and historical gendered discourses, and as a result the white women participants in this study continue to create place and ascribe space in digitally mediated and material versions of their homes. Furthermore, the resurgence of middle class postfeminist accounts of domesticity have promoted domestic idealism and many women have migrated back to the home spurred on by popular media, and economic privilege that has allowed them to forego paid employment. This study also shows that white, middle class women participants were offered choices to construct their own postfeminist narratives of domesticity. On the other hand, the black women employed as domestic workers by these middle class couples, were largely absent from such narratives and conversations. Findings further suggest that domestic space and place remained the domain of white women participants, and that white men were able to renegotiate their domestic responsibilities because they remained distant from domestic narratives and conversations, where they were largely associated with domestic inadequacy.

Abstract:

This thesis addresses the following question: How should domestic networks be reinvented to support self-management by domestic users? It takes a user-centred design approach to redesign the underlying domestic network infrastructure to better fit domestic users. The overall aim of this work is to create user-centred mechanisms to support self-management of domestic networks by domestic users. Two areas of the domestic network are studied in detail, user-centred mechanisms for domestic network infrastructure control and user-centred presentations of network data. User-centred mechanisms for domestic network infrastructure control are explored to improve Wi-Fi device association in domestic environments. A user-centred design approach is adopted to create a new method for sharing Wi-Fi credentials between devices, specifically tailored for domestic environments called MultiNet. The network performance impact of MultiNet is quantified using the standard metrics of throughput, latency, and jitter in a lab based experiment. MultiNet's usability is then compared to Wi-Fi Protected Setup in a lab based usability evaluation. These show that better Wi-Fi device association methods targeted for domestic environments can be built. It also shows that user-centred networking infrastructure can support self-management by domestic users. User-centred presentations of network data address the poor legibility of domestic networks hinders configuration and maintenance of them. A user-centred approach is adopted to design and construct a network data visualisation and annotation platform, HomeNetViewer. Through a series of deployments in real households the HomeNetViewer platform is used to explore user-centred presentations of network data to support the local negotiation of domestic network policy. HomeNetViewer improves domestic network legibility by enabling the construction of user-centred presentations of domestic network data. Additionally, it shows that users are comfortable annotating their network data using activities, applications, and users as a vocabulary. Together this highlights, with the correct user-centred tools, that domestic users are able to gain new insight into their networks to support self-management. HomeNetViewer also shows that manually annotating domestic traffic place an ongoing burden on the users. Automating user-centred presentations of network data are explored to address the burden the annotation process places on users. The use of enterprise traffic classification techniques to generate user-centred presentations of network data struggle to classify the data annotated by HomeNetViewer participants. It concludes by suggesting two ways in which these difficulties could be addressed in future work. Overall the domestic access point provides an important point of configuration, visibility and control over the domestic network infrastructure. This dissertation demonstrates that taking a user-centred design approach to reinventing the domestic network, to support self-management by users, can resolve the existing problems and merits further research and exploration by industry and standardisation bodies.

Abstract:

Désormais, l'accès Internet à haut débit est largement répandu et de nombreuxutilisateurs se connectent à l'Internet depuis chez eux. Ces utilisateurs n'ont pas de moyen simple pour résoudre les problèmes de performance. À la place, les utilisateurs appellent leur fournisseur d'accès même quand un problème provientdu réseau domestique. Cette situation frustrante pour les utilisateurs engendreune dépense importante chez les fournisseurs d'accès. Dans cette thèse, nous étudions des techniques permettant à un client finald'identifier si les problèmes de performances apparaissent dans le réseaudomestique ou non. Nous montrons que le réseau domestique peutaffecter la performance de bout-en-bout et les techniques de diagnosticexistantes ne peuvent pas toujours identifier si le réseau domestique est legoulot d'étranglement de performance. Nous concevons HomeNet Profiler, unlogiciel qui mesure la liste des appareils actifs dans le réseau domestique,l'implémentation du protocole UPnP dans les passerelles Internet, etl'environnement WiFi des réseaux domestiques. Les 3000 réseaux domestiquesqu'HomeNet Profiler mesure sont de petite taille mais peuvent avoir jusqu'à 20appareils. Les requêtes UPnP permettent de détecter le cross-traffic et dedifférencier les pertes réseaux dans le réseau domestique des pertes réseaudans le reste de l'Internet. De plus, l'environnement WiFi est généralementdense. Pour mettre à profit les environnement WiFi denses, nous concevons destechniques de mesures bénéficiant du voisinage WiFi et qui sont capables demesurer séparément le délai et le taux de perte du lien montant et du liendescendant
Broadband Internet access is now widespread and many users connect to theInternet from home. Often, Internet users at home are not computer. When aperformance problem occurs, users have no simple means to diagnose the problemand may call their Internet service provider to fix the problem, even if theproblem comes from the user network. This situation frustrates Internet usersand incurs a large cost on the Internet service providers which must provisioncall centers. In this thesis, we consider techniques for end-hosts to pinpoint whetherperformance problems occur in the home network or not. We show that some homenetwork configurations affect the end-to-end performance and that existingtechniques cannot always pinpoint whether the home network is the performancebottleneck. To get a better understanding of existing home networks at large,we design HomeNet Profiler, a software measurement tool to measure the list ofdevices active in the home network, the implementation of UPnP in residentialhome gateways, and the WiFi environment inside home networks. With our datasetconsisting of nearly 3000 homes, we show that home networks are often small butcan have up to 20 devices. We demonstrate that UPnP queries, can pinpointcross-traffic from the home network and differentiate local from wide-arealosses. We also show that the home WiFi environment is generally dense and hasan inherent risk for interference. To leverage and take advantage of this highWiFi density, we design neighbor-assisted diagnosis techniques. Thesetechniques are able to efficiently detect and distinguish uplink and downlinkdelays and loss rates with small error

Abstract:

More than a billion people access the Internet through residential broadband connections worldwide, and this number is projected to grow further. Surprisingly, little is known about some important properties of these networks: What performance do users obtain from their ISP? What factors affect performance of broadband networks? Are users bottlenecked by their ISP or by their home network? How are applications such as the Web affected by these factors? Answering these questions is difficult; there is tremendous diversity of technologies and applications in home and broadband networks. While a lot of research has tackled these questions piecemeal, the lack of a good vantage point to obtain good measurements from these networks makes it notably difficult to do a holistic characterization of the ﾓlast mileﾔ. In this dissertation we use the home gateway to characterize home and access networks and mitigate performance bottlenecks that are specific to such networks. The home gateway is uniquely situated; it is always on and, as the hub of the network, it can directly observe the home network, the access network, and user traffic. We present one such gateway- based platform, BISmark, that currently has nearly 200 active access points in over 20 countries. We do a holistic characterization of three important components of the last mile using the gateway as the vantage point: the access link that connects the user to the wider Internet, the home network to which devices connect, and Web performance, one of the most commonly used applications in today's Internet. We first describe the design, development, and deployment of the BISmark platform. BISmark uses custom gateways to enable measurements and evaluate performance opti- mizations directly from home networks. We characterize access link performance in the US using measurements from the gateway; we evaluate existing techniques and propose new techniques that help us understand these networks better. We show how access link technology and home networking hardware can affect performance. We then develop a new system that uses passive measurements at the gateway to localize bottlenecks to either the wireless network or the access link. We deploy this system in 64 homes worldwide and characterize the nature of bottlenecks, and the state of the wireless network in these homes - specifically we show how the wireless network is rarely the bottleneck as throughput exceeds 35 Mbits/s. Finally, we characterize bottlenecks that affect Web performance that are specific to the last mile. We show how latency in the last mile results in page load times stagnating at throughput exceeding 16 Mbits/s, and how simple techniques deployed at the gateway can mitigate these bottlenecks.

Abstract:

Critical networks e.g. telecare services, telemonitoring, are implemented to provide the information security and reliability that the end user desires, especially during an emergency. Unlike business carrier systems that are planned for the general public’s use, critical communication systems are designed particularly for public protection and other serious communication situations. Availability and reliability of such networks is highly desirable. The following thesis works to compare and analyze a variety of communication access technologies to find out the best primary means of data transportation for health critical services and model reliable communication link by using redundancy. This study also provides an efficient failover mechanism to implement redundant links. This strategy is intended to provide the reliable communication and to protect the established communication link.

Abstract:

This theses project investigates and presents different threats that a network can be exposed to and the common protection techniques that can be applied, with a focus on the network perimeter – specifically the router/firewall between the local area network and the Internet. All Internet connected devices and networks are exposed to and affected by security threats to some degree, hence security is important in almost every type of network. With the constant growth of the Internet the 32-bit addressing scheme ipv4 is proving to be inadequate, and therefore the transition to the 128-bit addressing scheme ipv6 is becoming critical. With ipv6 comes new security threats (while still old threats remain) that requires an understanding of perimeter security. In this thesis we secure a home router and describe these steps to enable home and small business owners to secure their IPv6 network at a relatively low cost.
Detta projekt kommer att undersöka och presentera olika hot som ett IPv6 nätverk kan utsättas för samt de vanligaste skydds mekanismer som används idag, med fokus på nätverkets skallskydd mellan det interna lokala nätet och det yttre publika Internet. I stort sätt all Internet ansluten utrustning och nätverk är exponerad och påverkad i någon grad av säkerhets brister, säkerhet är en viktig del i stort sätt alla nätverk oavsett syfte eller verksamhet. Genom ett ständigt växande Internet börjar de 32-bitar adresser tillhörande IPv4 nätet ta slut, vilket gör behovet av att immigrera till 128-bitar adresser på IPv6 nätet allt mer kritiskt. Med IPv6 kommer nya säkerhetshot, samt att även vissa äldre hot kvarstår, som kräver en förståelse av perimeter skydd. I denna rapport säkrar vi en hemma router och beskriver för varje steg tillvägagångssättet för att hem och små företagare ska få möjlighet att skydda sina IPv6 nätverk till en relativt låg kostnad.

Abstract:

Gathering meaningful information from Home Networking (HN) environments has presented researchers with measurement strategy challenges. A measurement platform is typically designed around the process of gathering data from a range of devices or usage statistics in a network that are specifically behind the HN firewall. HN studies require a fine balance between incentives and impediments to promote usage and minimize efforts for user participation with the focus on gathering robust datasets and results. In this dissertation we explore how to gather data from the HN Ecosystem (e.g. devices, apps, permissions, configurations) and feedback from HN users across a multitude of HN infrastructures, leveraging low impediment and low/high incentive methods to entice user participation. We look to understand the trade-offs of using a variety of approach types (e.g. Java Applet, Mobile app, survey) for data collections, user preferences, and how HN users react and make changes to the HN environment when presented with privacy/security concerns, norms of comparisons (e.g. comparisons to the local environment and to other HNs) and other HN results. We view that the HN Ecosystem is more than just “the network” as it also includes devices and apps within the HN. We have broken this dissertation down into the following three pillars of work to understand incentives and impediments of user participation and data collections. These pillars include: 1) preliminary work, as part of the How's My Network (HMN) measurement platform, a deployed signed Java applet that provided a user-centered network measurement platform to minimize user impediments for data collection, 2) a HN user survey on preference, comfort, and usability of HNs to understand incentives, and 3) the creation and deployment of a multi-faceted How's My Network Mobile app tool to gather and compare attributes and feedback with high incentives for user participation; as part of this flow we also include related approaches and background work. The HMN Java applet work demonstrated the viability of using a Web browser to obtain network performance data from HNs via a user-centric network measurement platform that minimizes impediments for user participation. The HMN HN survey work found that users prefer to leverage a Mobile app for HN data collections, and can be incentivized to participate in a HN study by providing attributes and characteristics of the HN Ecosystem. The HMN Mobile app was found to provide high incentives, with minimal impediments, for participation with focus on user Privacy and Security concerns. The HMN Mobile app work found that 84\% of users reported a change in perception of privacy and security, 32\% of users uninstalled apps, and 24\% revoked permissions in their HN. As a by-product of this work we found it was possible to gather sensitive information such as previously attached networks, installed apps and devices on the network. This information exposure to any installed app with minimal or no granted permissions is a potential privacy concern.

Abstract:

This thesis examines home entertainment network remote configuration solutions. It does so by inspecting four home entertainment networking solution specifications - HAVi, Jini, AV/C and UPnP. Two of these (AV/C and UPnP) are implemented partially for a system allowing a TV to configure an AudioNideo Receiver (AV/R) remotely on the network (a process known as remote configuration). The two implementations are then more closely investigated and several implementation differences in the approach between the remote configuration method of device configuration and other methods of device configuration are discerned. These different approaches are then categorised into one of two theoretical models of communication for configuring devices on home entertainment networks - the Rendering model and the Programmed model. By classifying a particular method of device configuration into one of the two models, manufacturers can quickly determine the inherent strengths and weaknesses of that method

Abstract:

With the fast development of wireless networks and devices, Mobile IP is expected to be used widely so that mobile users can access the Internet anywhere, anytime without interruption. However, some problems, such as firewall traversal and use of private IP addresses, restrict use of Mobile IP. The objective of this thesis is to design original schemes that can enable a mobile node at abroad to access its home network as well as the Internet securely and that can help Mobile IP to be used widely and commercially. Our solutions are secure, efficient, and scalable. They can be implemented and maintained easily. In this thesis, we mainly consider Mobile IPv4, instead of Mobile IPv6. Three research topics are discussed. In each topic, the challenges are investigated and the new solutions are presented. The first research topic solves the firewall traversal problems in Mobile IP. A mobile node cannot access its firewall-protected home network if it fails the authentication by the firewall. We propose that an IPsec tunnel be established between the firewall and the foreign agent for firewall traversal and that an IPsec transport security association be shared by the mobile node and a correspondent node for end-to-end security. The second topic researches further on firewall traversal problems and investigates the way of establishing security associations among network entities. A new security model and a new key distribution method are developed. With the help of the security model and keys, the firewall and the relevant network entities set up IPsec security associations to achieve firewall traversal. A mobile node from a private home network cannot communicate with other hosts with its private home address when it is visiting a public foreign network. A novel and useful solution is presented in the third research topic. We suggest that the mobile node use its Network Access Identifier (NAI) as its identification and obtain a public home address from its home agent. In addition, a new tunnel between the mobile node and its home agent is proposed.

Abstract:

The purpose of this study was to investigate how dropped messages can be avoided during the service discovery process of the Universal Plug and play (UPnP) protocol in home networks. Another aim involved determining the causes of those messages being dropped during the service discovery process, with many protocols being examined. The thesis proposes an algorithm that can compute the .,/]1tr)imum period of time .. required between a consecutive burst of services' reply messages and that determines the minimum required queue sizes for the routers' nodes to manage the traffic and avoid dropped messages. The proposed solution is applied at the application layer in' end nodes, not router nodes, as this would reduce the load on router nodes, freeing them up for other routing functions. The solution takes into consideration many of the network parameters such as network size, message size and existing traffic. An NS2 simulator was used to examine the produced algorithm on two different network configurations - centralized and decentralized - which was tested with three different types of queue management algorithms: drop tail, Random Early Detection (RED) and Random Exponential Marking (REM). In addition, its functionality was examined in a hybrid network, which included both wired and wireless connections. The results show an improvement in the discovery rate and a reduction in the number of dropped messages, highlighting the capability of the proposed algorithm in dealing with modifications to the network topology and in changing the density of the existing traffic. The principal conclusion was that the UPnP scales up well with its extensive use of messaging through managing the rate of replied services' messages.

As the Internet of Things (IoT) grows, malware will increasingly threaten Internet security and stability. Many actors, from individuals installing antivirus on their personal computers to law enforcement conducting botnet takedowns, have some capability to prevent or remediate malware, but these strategies face technical and economic challenges. These challenges worsen as the IoT expands, due to the high number of IoT devices and other characteristics of the IoT. Fortunately, Internet Service Providers (ISPs) are positioned to effectively contribute to malware remediation efforts, through the detection and notification of compromise. However, Network Address Translation (NAT) and IPv6 Privacy Extensions prevent ISPs from identifying the specific compromised device. We refer to this lastmile extension of the IP traceback problem as the residential source identification problem. As the IoT grows, the problem worsens: IoT devices are less capable of self-remediation and expected to soon outnumber traditional devices, thus imposing a significant cost on customers to triangulate and remediate an infection. To address the residential source identification problem, I propose EDICT, an open-source software package for home routers that will enable consumers to identify a specific device, given retrospective notification of the malicious behavior, without compromising the consumer's privacy. EDICT does this by maintaining a mapping of IP flows to devices through a series of scalable Bloom filters, allowing EDICT to operate under the significant memory constraints of home routers. When a customer is informed of compromise, EDICT will query this connection log using a fuzzy check of the timestamp and source port, both provided by the ISP, iterated across a log of identified devices. EDICT will then provide the customer with user-friendly information on the infection's source, enabling remediation.As the Internet of Things (IoT) grows, malware will increasingly threaten Internet security and stability.

Abstract:

To implement a utility wireless sensor network, investigation of different wireless protocols has been performed. The protocols are Bluetooth, Wi-Fi, IEEE 802.15.4 and Zigbee. Consecutively literature studies have made it comprehensible to understand the function of the protocols that are suitable for development of wireless sensor networks. The importance of low cost, low power, reliable and high-quality properties for long distances are significant. IEEE 802.15.4 and Zigbee protocol are proper to implement as a wireless sensor network.

To reduce the human efforts in the configuration of the system, a comfortable method is implemented to facilitate the procedure. The applied method is based on an automatic configuration of the system. The configuration and the decision taking are implemented in the software. The system is designed to avoid interference to other wireless networks with the possibilities of reconfiguration.

A uniform hardware and software design with separate functions of the system decided by a subsequent command for configuration is preferable. This imposes an advantage that increases the flexible potential of the system when a uniform solution is implemented.

To support the basic communication principles and control of the system, a buffer implementation has been introduced. The functionality of decision taking is distributed, configured by system commands from the host system. Detecting of system commands requires a properly operating buffer management. In consideration to the power consumption in reference to battery utilizations, the settings of RF-module and microcontroller have a powerful impact to reduce the power consumption. All possibilities of hibernates and avoidance of unnecessarily transmitting, should be deactivated to minimize the power consumption.

Abstract:

Broadband connectivity has increased significantly the last years. More and more households choose to subscribe to services from various broadband companies. This has led to a range of new services. Some of these have high demands to both bandwidth and quality of service. Network operators have until recently neglected the challenges of providing network coverage within customer homes. Wireless solutions have been widely used, but new and demanding services like HDTV will either need a wired network or a significantly improved wireless standard. The complexity of in-home connectivity has increased dramatically because of a constant increasing number of devices and severe technical requirements. Convergence of earlier separated services is one of the main reasons for these new technical challenges. Different services with various demands are delivered over the same physical pipeline. The convergence of television, Internet and voice services, known as triple play, is delivered by both cable and fibre network operators today. Telecom operators are looking for ways to deliver triple play to compete in this new market. In addition to technical challenges, high costs and uncertain revenues slow down the development. In this thesis, we look at general technical requirements as well as business aspects regarding the development of a home network solution. Various technical solutions for in-home wiring are discussed. Because of high costs attended with installation of new wires in people's homes, usage of existing wiring is recommended. Power line technology (HomePlug) as well as data over coax and copper (HomePNA) are presented as actual solutions. Wireless LAN standards are mentioned and the new 802.11n standard is recommended as the next WLAN solution to be embedded in the future home network. The support of Ethernet is also recommended beacause it is well proven and delivers high bandwidth as well as low latency and jitter. The support for these various interfaces should be embedded in the Residential Gateway (RG) which is delivered by the network operator and resides in the transition between the access network and the home network. The RG is "the brain" in the home network and controls all services. One of the main tasks for the RG, is to deliver the appropriate Quality of Service (QoS) for the different services. This is done through a remote management system that ensures end-to-end QoS. The establishment of triple play leads to changes in existing business models. Telephone companies, broadcasters and cable network operators are among the involved actors. How to increase customers' value and how to ensure return on investment are central questions regarding the development of a triple play business model. Revenues must be ensured to get acceptance among stakeholders. A general business model for a network operator launching triple play is presented in the thesis. The model is based on a pre-defined business model ontology and uses elements from the involved actors' existing models. The establishment of the "connected home" which emphasize ease of use and personalization is central in the proposed value proposition. A home network user interface accessible from the various in-home devices is recommended to ensure customer control and user friendliness. Services like video on demand, personal video recording, interactive television and Internet should be accessible through the user interface. The network operator should differentiate from competitors by offering their customers a complete home network solution where ease of use, performance and personalization are emphasized. Partnerships with actors in the content and advertising industry as well as equipment manufacturers are discussed. To ensure low cost and high quality equipment as residential gateways and set top boxes, good partnerships with equipment manufacturers are essential. TV channels and independent content must be retrieved through partnerships with the copyright holders of the content. By making content available independent of TV-channels, network operators can take over parts of the television business which is operated by broadcasters and television programmers today. VoD and pay-per-view services will probably gradually take over for existing television services. Network operators have a golden opportunity to take over great shares of this business. Advertising can generate important revenues for network operators. The ability to personalize advertisements and offer shopping directly from the TV-set increases the value of advertising. Commercials can be displayed in the home network user interface and in connection with services as video on demand. Content with commercials attached can be offered at reduced price or for free, hence intercepting the customers with low willingness to pay. The financial aspects regarding home network solutions are discussed generally and with a low detailing level in this thesis. Huge costs are connected with the development of triple play and home network solutions, but there is also a high potential for revenue generating services and income from advertising and shopping. But, to generate any revenues, the network operator is dependent on customers. Hence, acquiring and retaining customers by delivering highly valued services and good customer support is the key to success.

Abstract:

A home network is a popular method of allowing computers to communicate with each other within a given residential area or a local area network. Homes are the new frontiers of technology in the current global scenario, a digital interconnected home network is a reality and an efficient means to exchange information seamlessly across different homes and across different geographies is the need of the hour. The interconnection of different homes is possible with the existing ADSL subscriptions but would need changes in the existing gateway structures, which could be challenging for the less techno-savvy. In an effort to make life easier for the end user and help making the interconnection between various home networks seamless, a small device called I-Box is introduced through this project, which is essentially a small UPnP device with rich features and functionalities. This thesis gives an overview of the I-Box technology and with the help of various popular theoretical frameworks and concepts, investigates available Marketing channels and suggests a suitable deployment strategy for the I-Box by making a comparative study of the various possible scenarios and thereby identifying the most suitable model for its deployment.

Abstract:

This thesis is a service design project that has been carried out in cooperation with the telecom company Telia Sweden (belonging to TeliaSonera AB). The purpose of the report was to examine Telia's fixed broadband service for private customers from a customer perspective. Previously, the service has mainly been developed from a technology-driven perspective. During the broadband subscription, the customers are able to borrow a router from Telia but it has been noticed that some customers opt out Telia’s router. The objective of this work has been to deliver useful customer insights and improvement proposals to Telia within the framework of the broadband service. In the project, a service design methodology was used where the focus has been on interactions with customers. The interactions consisted of in-depth qualitative interviews. The project consisted of five phases. An initial preparation phase with a literature study on service design methods, the Internet and broadband technology as well as learning about and understanding the company. During the preparation phase internal hypotheses about the service problem areas were collected. The initial phase was followed by three iterative loops with customer interactions, insight analysis, ideation and conceptualization. Customer insights and concepts have been tested, evaluated, and deepened during the project. In the last phase the result was processed and the insights were rated for easier implementation. A major problem area for many customers was the Wi-Fi and Wi-Fi range, because the technology is perceived as difficult and abstract. The conclusion is that Telia should help their clients to improve the Wi-Fi quality and the project work led to three ultimate concepts tested on customers. Also six recommendations were delivered to Telia.
Detta examensarbete är ett tjänstedesignprojekt som har utförts i samarbete med telekombolaget Telia Sverige (tillhörande TeliaSonera AB). Syftet med rapporten har varit att undersöka Telias fasta bredbandstjänst för privatpersoner ur ett kundperspektiv. Tidigare har tjänsten främst utvecklats utifrån ett teknikdrivet perspektiv. Under tiden som bredbandskund hos Telia får kunden låna en router men Telia har märkt att en del kunder väljer bort routern. Målet för arbetet har varit att leverera användbara kundinsikter och koncept på förbättringsförslag till Telia inom ramen för bredbandstjänsten. I projektet har en tjänstedesignmetodik använts där fokus har legat på interaktioner med kunderna. Interaktionerna har bestått av djupgående kvalitativa intervjuer. Projektet har bestått av fem faser. En inledande förberedande fas med förstudie om bland annat tjänstedesignmetoder, internet och bredbandstekniken, samt tid för att lära känna och förstå företaget. Under den förberedande fasen samlades även interna hypoteser om tjänstens problemområden in. Den inledande fasen följdes av tre iterativa loopar med kundinteraktioner, insiktsanalys, idégenerering och konceptualisering. Kundinsikter och koncept har testats, utvärderats och fördjupats under projektets gång. I den sista fasen bearbetades och rangordnades resultatet för att insikterna lättare ska kunna implementeras på företaget. Ett stort problemområde för många kunder var Wi-Fi och Wi-Fi-täckningen, då tekniken upplevs som svår och abstrakt. Slutsatsen är att Telia borde hjälpa sina kunder att själva förbättra Wi-Fikvalitén och arbetet ledde fram till tre slutgiltiga koncept som testades på kunder och utvärderades. Även sex rekommendationer till Telia levererades.

Abstract:

The growth of broadband Internet access across the world for the last 10 years has made new business models possible. Services which before mainly were provided by network operators and in dedicated networks have now migrated to the open Internet. This has created a global service provider market, using the Internet as platform. The network operators are in many cases left with only providing the broadband access service. For the global service providers, continuous effort is put into the field of finding smart methods for bringing new and advanced services to the market without asking for e.g. QoS features from the involved network operators. This type of service delivery is called Over-The-Top (OTT). The concept of making services able to adapt their network and transport requirements during time of delivery is a strong contribution to success for OTT services. The focus of the work in this thesis, is methods for improving various aspects - as defined by my research questions - related to QoS and potentially also QoE for dynamic adaptive video streaming over HTTP (DASH) services. The motivation for focusing on video services is based on their high QoS requirements (i.e. bandwidth) and also popularity in terms of usage. In the work presented in this thesis, I have studied the behaviour and performance of DASH services by means of simulations, measurements and experiments. Based on insight obtained through this, I established a hypothesis on how QoS and QoE aspects could be improved for users present in the same home network environment. My hypothesis was that making more accurate information available about both services and network conditions in near real-time could facilitate improved control methods. The effectiveness of my suggested methods have in most cases been analysed by means of implementation in an experimental lab scenario, and supported by simulations and analytical approaches when appropriate. The findings presented in the included papers are all closely related and map into the research model used. This model is composed of Knowledge Plane, Monitor Plane and Action plane components located in both service endpoints and involved network components. As my main focus has been on OTT service delivery, the main contributions of my work apply to service endpoints, i.e. components in the home network and on the server side. The server side would in many cases be represented by a Content Delivery Network (CDN) node. The main research questions identified are: RQ1: In a home network how to (autonomously) control the performance of DASH based services. RQ2: How to provide fairness and stability for competing DASH sessions using service endpoint functionality. RQ3: How to choose appropriate quality levels for a DASH session. The main contributions from my research are: C1: A method for controlling the quality levels of DASH in the home gateway. C2: A method for improving fairness among competing DASH sessions. C3: A method for shaping traffic aggregates on access links with DASH components. C4: A method for estimating available bandwidth on access links when DASH sessions are present.

Abstract:

During the past few years, Power Line Communications (PLC) have become a popular connectivity solution to answer the growing need of home networks for bandwidth. As wireless technologies, this solution spares the user from cabling its Local Area Network (LAN), by directly using the home power grid as a transmission medium. While PLC generally offer a larger coverage than Wireless Local Area Networks (WLAN), the capacity offered by current systems is not sufficient to simultaneously support bandwidth intensive streams. In this thesis, we aim at exploring various solutions for future PLC networks. Firstly, we aim at improving the spectral efficiency of the current systems' Physical (PHY) layer, where two modulation schemes are compared. On the one hand, we study the modulation deployed in current PLC networks, called windowed Orthogonal requency Division Multiplexing (OFDM), and we highlight the main limitation of this solution in the particular context of PLC. On the other hand, we show that and alternative solution, called OFDM/Offset Quadrature Amplitude Modulation (OQAM), offers some degrees of freedom which could highly benefit to PLC networks. Secondly, the study is oriented toward the Media Access Control (MAC) layer of PLC systems, considering a multiuser utilization of the network. In this second part, we aim at proposing allocation solutions that will allow a more efficient utilization of the limited and shared transmission resource. We firstly study the opportunity of defining an Orthogonal Frequency-Division Multiple Access (OFDMA) transmission scheme for point-to-multipoint transmissions, in order to increase data rates by taking advantage of the diversity between users' channels. Finally, the last Chapter is dedicated to the study of broadcast and multicast communications in PLC networks, where we show that a smart aggregation of the set of users to reach could greatly improve efficiency of multicast transmissions.

Abstract:

Homes are involved in a significant fraction of Internet traffic. However, meaningful and comprehensive information on the structure and use of home networks is still hard to obtain. The two main challenges in collecting such information are the lack of measurement infrastructure in the home network environment and individuals’ concerns about information privacy. To tackle these challenges, the dissertation introduces Home Network Flow Logger (HNFL) to bring lightweight privacy-preserving passive measurement to home networks. The core of HNFL is a Linux kernel module that runs on resource-constrained commodity home routers to collect network traffic data from raw packets. Unlike prior passive measurement tools, HNFL is shown to work without harming either data accuracy or router performance. This dissertation also includes a months-long field study to collect passive measurement data from home network gateways where network traffic is not mixed by NAT (Network Address Translation) in a non-intrusive way. The comprehensive data collected from over fifty households are analyzed to learn the characteristics of home networks such as number and distribution of connected devices, traffic distribution among internal devices, network availability, downlink/uplink bandwidth, data usage patterns, and application traffic distribution.

Abstract:

A promising, yet relatively small, body of academic scholarship on UK home-education has emerged in recent years. However, it persists as an area of research marked by partisanship. The digital age is often heralded as an era of liberation; empowering disparate groups to network, exchange practice, and learn from one another. However, few have considered what this might mean for home-education. This study sought to answer the overdue call for research in this area. This thesis is a mixed methods study; based on an online survey of 242 home-educators and 52 individual and group interviews with 85 parents, children and young people who used a range of new technologies. These families resided in different localities across England, Wales and Scotland. The analyses explored the role of new technologies, knowledge and learning within the themes of community, pedagogy and identity. The findings indicated that home-educating families participate in a diverse landscape of online networks and offline communities. New technologies have been effective in mobilising support at times of ‘threat’. It was also found that participation in this landscape has given new home-educators access to resources and confidence in their practice. The use of these resources and networks over time suggests a pedagogical journey that strengthens the transmission of values and production of identity, as learners get older. It concluded that home-education invites ideological conflict and internal struggle and that the appropriation of new technologies has both freed families from the old structures of school and placed them into new ones. This study sheds light on how some learning communities are transforming and being transformed by the tools used to reach an alternative destination in education. For home-education, the mixed role of new technologies surfaces a series of unresolved tensions, paradoxes and unanswered questions.

Abstract:

Au cours des dernières années, la révolution numérique a continué sa progression. Les technologies de l'information et des communications (TIC) ont totalement changé la vie quotidienne des gens à leur domicile (concept de « maison numérique »). Pendant ce temps, non seulement le volume des émissions de CO2 produit par les TIC, ce qu'on appelle l'empreinte carbone, est sans cesse en croissance mais elle s'accompagne également d'une hausse du prix de l'électricité, augmentant fortement la part des équipements numériques dans la budget global des ménages. Ainsi, pour des raisons environnementale et économique, réduire la consommation d'énergie dans les nombreux équipements du réseau domestique est devenu un enjeu majeur. Dans ce contexte, la thèse porte sur la conception, l'évaluation et la mise en œuvre d'un ensemble de mécanismes dans le but de répondre aux problèmes de consommation d'énergie sur les réseaux locaux rassemblant les équipements numériques domestiques. Nous proposons un réseau de contrôle qui est formé par des noeuds de contrôle de l'énergie placés au-dessus du réseau traditionnel. Chaque nœud de contrôle est relié à un dispositif en vue de coordonner les états d'alimentation de l'équipement domestique associé.. Un démonstrateur pour un système Home Power Efficiency (HOPE) a également été mis en œuvre. Il démontre la faisabilité de la solution technique que nous proposons pour le contrôle de l'énergie dans un réseau domestique réel avec des scénarios réels qui sont souvent utilisées par utilisateur. Après avoir analysé le mode d'utilisation des équipements du réseau domestique, nous proposons un système de gestion d'énergie qui contrôle ces équipements minimisant ainsi que leur consommation. Le système est basé sur l'analyse des services collaboratifs, chaque service est découpé en blocs fonctionnels atomiques, distribués dans les différents équipements. Cela permet de gérer avec plus de précision les besoins énergétiques de chaque équipement de manière à n'alimenter que les composants nécessaires au service demandé. Pour conclure ces travaux, nous avons également cherché à minimiser les impacts de l'économie d'énergie sur la qualité d'expérience perçue par l'utilisateur (notamment le délai d'activation des services). Nous proposons un système de gestion d'énergie pour des services collaboratifs offrant plusieurs compromis possibles entre la consommation d'énergie et le délai d'activation des services dans un réseau domestique. Il est complété par un algorithme d'apprentissage du comportement des utilisateurs domestiques
In recent years, Information and Communications Technology (ICT) has totally changed the people daily life in the Digital Home. Meanwhile, not only the amount of CO2 emission of ICT, so called ''footprint'', is increasing without cease, but also the price of electricity is constantly rising. Thus, it is quite important to reduce energy consumption in the home network and home devices for the environmental and economic reasons. In order to cope with this context, the thesis concerns the design, the evaluation, and the implementation of a novel set of mechanisms with the purpose of responding to home network energy consumption problems. We proposed firstly an Overlay Energy Control Network which is formed by the overlay energy control nodes. Each node is connected to one device which forms an overlay control network to coordinate the power states of the device. Then, a testbed for HOme Power Efficiency system (HOPE) is implemented to demonstrate the technical solution for energy control in a real home network environment with several frequently used scenarios. After analyzing user's way of use of their home network equipment, we propose a power management which controls the devices based on the analysis of the collaborative services. These frequently used collaborative services require different functional blocks in different devices. This model provides the possibility to turn on the right requested functional blocks in the right device at the right moment. Finally, based on the former contribution, the collaborative overlay power management offers several possible tradeoffs between the power consumption and the waiting delay in the home network

Abstract:

The Mobile IPv6 (MIPv6) protocol enables mobile nodes (MNs) to remain connected to other correspondent nodes (CNs) while roaming the IPv6 Internet. Home and correspondent registrations are essential parts of the MIPv6 protocol, whereby MNs register their care-of addresses (CoAs) with their home agents (HAs) and with their CNs, respectively. Security provision for home and correspondent registrations is a fundamental part of the MIPv6 protocol and has been an open research issue since the early stages of the protocol.This thesis examines state-of-the-art protocols for securing home and correspondent registrations in MIPv6 networks. The strengths and weaknesses of these protocols are discussed. The investigation of these protocols leads to the proposal of an enhanced home registration protocol and a family of correspondent registration protocols. The Enhanced Home Registration (EHR) protocol extends the basic home registration protocol defined in MIPv6 to support the location authentication of MNs to their HAs. The EHR is based on novel ideas of segmenting the IPv6 address space, using a symmetric CGA-based technique for generating CoAs, and applying concurrent CoAs reachability tests. As a result, EHR is able to reduce the likelihood of a malicious MN being successful in luring an HA to flood a third party with useless packets using MIPv6. In addition, EHR enables HAs to help in correspondent registrations by confirming MNs' CoAs to CNs. Simulation studies of EHR have shown that it only introduces a marginal increase in the registration delay, but a significant increase in the signalling overhead as a cost of supporting the location authentication of MNs.The thesis also proposes a family of correspondent registration protocols. These protocols rely on the assistance of home networks to confirm the MNs' ownership of the claimed HoAs and CoAs. The protocols consist of three phases: a creation phase, an update phase and a deletion phase. Informal and formal protocol analyses have confirmed the protocols' correctness and satisfaction of the required security properties. The protocols have been simulated extensively and the results show that they produce lower registration delay and a reduction in the signalling overhead during update and deletion phases. This is at the cost of a varying increase, depending on the protocol variant, in the registration delay and signalling overhead during the creation phase.

Abstract:

Les réseaux domestiques sont confrontés à une évolution continue et deviennent de plus en plus complexes. Leur complexité a évolué selon deux dimensions interdépendantes. D'une part, la topologie du réseau domestique devient plus complexe avec la multiplication des équipements et des technologies de connectivité. D'autre part, l'ensemble des services accessibles via le réseau domestique ne cesse de s’élargir. Un tel contexte a rendu la gestion du réseau domestique plus difficile pour les Fournisseurs d’Accès Internet (FAI) et les utilisateurs finaux. Dans ce manuscrit, nous nous concentrons sur la deuxième dimension de la complexité décrite ci-dessus liée au trafic circulant depuis/vers le réseau domestique. Notre première contribution consiste à proposer une architecture pour la supervision du trafic dans les réseaux domestiques. Nous fournissons une étude comparative de certains outils open source existants. Ensuite, nous effectuons une évaluation de performances expérimentale d’un sous ensemble des processus impliqués dans notre architecture. Sur la base des résultats obtenus, nous discutons les limites et les possibilités de déploiement de ce type de solution. Dans notre deuxième contribution, nous présentons notre analyse à large échelle des usages et du trafic résidentiel basée sur une trace de trafic réelle impliquant plus de 34 000 clients. Premièrement, nous présentons notre méthode de collecte et de traitement des données. Deuxièmement, nous présentons nos observations statistiques vis-à-vis des différentes couches de l’architecture Internet. Ensuite, nous effectuons une analyse subjective auprès de 645 clients résidentiels. Enfin, nos résultats fournissent une synthèse complète des usages et des caractéristiques des applications résidentielles. Dans notre troisième contribution, nous proposons une nouvelle méthode pour la classification en temps réel du trafic résidentiel. Notre méthode, laquelle est basée sur l’utilisation d’un algorithme d’apprentissage statistique de type C5.0, vise à combler les carences identifiées dans la littérature. Ensuite, nous détaillons notre implémentation d’une sonde légère sur un prototype de passerelle résidentielle capable de capturer, de suivre et d'identifier d’une manière fine les applications actives dans le réseau domestique. Cette implémentation nous permet, en outre, de valider nos principes de conception via un banc d'essai réaliste mis en place à cet effet. Les résultats obtenus indiquent que notre solution est efficace et faisable
Home networks are facing a continuous evolution and are becoming more and more complex. Their complexity has evolved according to two interrelated dimensions. On the one hand, the home network topology (devices and connectivity technologies) tends to produce more complex configurations. On the other hand, the set of services accessed through the home network is growing in a tremendous fashion. Such context has made the home network management more challenging for both Internet Service Provider (ISP) and end-users. In this dissertation, we focus on the traffic dimension of the above described complexity. Our first contribution consists on proposing an architecture for traffic monitoring in home networks. We provide a comparative study of some existing open source tools. Then, we perform a testbed evaluation of the main software components implied in our architecture. Based on the experiments results, we discuss several deployment limits and possibilities. In our second contribution, we conduct a residential traffic and usages analysis based on real trace involving more than 34 000 customers. First, we present our data collection and processing methodology. Second, we present our findings with respect to the different layers of the TCP/IP protocol stack characteristics. Then, we perform a subjective analysis across 645 of residential customers. The results of both evaluations provide a complete synthesis of residential usage patterns and applications characteristics. In our third contribution, we propose a novel scheme for real-time residential traffic classification. Our scheme, which is based on a machine learning approach called C5.0, aims to fulfil the lacks identified in the literature. At this aim, our algorithm is evaluated using several traffic inputs. Then, we detail how we implemented a lightweight probe able to capture, track and identify finely applications running in the home network. This implementation allowed us to validate our designing principles upon realistic test conditions. The obtained results show clearly the efficiency and feasibility of our solution

Abstract:

It would be unaffordable if the WDM-PON technologies were directly applied for massive deployment. Hence, the potential WDM-PON is to be integrated and improved in order to adapt it for NGPON and the future 5G. The UDWDM-PON can be considered as an ultimate solution for the next-generation access network capable of providing unlimited bandwidth for each user, thanks to the coherent detection. Plenty of scientists have believed that it is crucial to increase the operating speed and maximum reach of WDM-PON, while it has no sense if people achieve them without a ordable cost. In order to apply them cost-effciently, the system should require colorless ONUs and bidirectional systems. It is desired that the whole system use modulators on a low bias consumption, even limit the number of amplifiers. However, for bidirectional transmission the backscattering effects would limit the performance if we want to reuse the carrier from OLT. So, we should design a method to separate the wavelength between upstream and downstream. The traditional UDWDM-PON uses 2 laser at ONU, in this thesis, the single-DFB based ONUs are presented with integrated devices. What is the most plausible configuration? The photonic devices such as RSOA, DEML, FML with advanced configurations are presented in this thesis with different applications. The proposed thesis includes these parts: key devices for WDM-PON and the chirp parameters of these integrated photonic devices are measured, the polarization independent RSOA with different applications is also included, demonstration of dual output DEML with bidirectional coherent UDWDM-PON transmission, mitigating residual AM of DEML for phase modulation, and fast tuning for the UDWDM channel via FML are described.
Por sus altos requerimientos técnicos, sería inasumible aplicar las tecnologías WDM-PON directamente para el despliegue masivo de Fiber-to-the-Home de nueva generación. Por lo tanto, el potencial se WDM-PON se debe integrar y mejorar con el fin de adaptarlo para NGPON y el futuro 5G. Hoy dia, operadores, usuarios y científicos, ven crucial augmentar la velocitat de funcionament y el alcance de las redes de acceso PON, si bien no tiene sentido conseguirlo con un coste inasequible. El UDWDM-PON puede considerarse como una solución definitiva para la red de acceso de próxima generación, capaz de proporcionar ancho de banda ilimitado para cada usuario, gracias a la detección coherente, por lo que en esta tesis se aborda su realización con un coste e integración prácticos. Con el fin de aplicarlos de manera rentable, el sistema debería exigir a las ONU que sean idénticas, si láseres preseleccionados o incoloros, y ser bidireccionales. Se desea que el conjunto de moduladores del sistema tengan en un bajo consumo, e incluso limitar el número de amplificadores. Sin embargo, para la transmisión bidireccional los efectos de retrodispersión limitarían el rendimiento si queremos volver a utilizar la portadora generada en la OLT. Por lo tanto, debemos diseñar un método para separar la longitud de onda en las transmisiones de bajada y de retorno del usuario a la central. El tradicional UDWDM-PON utiliza 2 láseres en la ONU; en esta tesis, las ONUs usan dispositivos integrados basados en un sólo DFB. ¿Cuál es la configuración más plausible? Los dispositivos fotónicos como RSOA, DEML, FML con configuraciones avanzadas se presentan en esta tesis con diferentes aplicaciones, que resuelven distintos problemas técnicos. La tesis incluye las siguientes partes: análisis y medida de dispositivos fotónicos clave para WDM-PON con modulación de fase, la independencia a la polarización de RSOA con diferentes aplicaciones, demostración de DEML con doble salida para transmisión bidireccional coherente UDWDM-PON, mitigación de AM residual de DEML para la modulación de fase, y la sintonía rápida de canal de UDWDM a través de FML.

Abstract:

In this dissertation, I examine how making infrastructure visible affects users' engagement with that infrastructure, through the case study of home networking. I present empirical evidence of the visibility issues that home networks present to users and how these results informed the design of a prototype called Kermit to visualize aspects of the home network. Through my implementation and evaluation of Kermit, I derive implications for making infrastructure visible in ways that enable end-users to manage and understand the systems they use everyday. I conclude with suggestions for future work for making home networks, and infrastructure more generally, more visible.

Abstract:

The advancement of the internet across the globe has made computer users implement several ways of protection against possible network threats. The goal of this thesis is to analyse vulnerabilities and threats that may occur in a home network and design a vulnerability classification for home users with the help of Kali Linux. The classification is proposed and briefly evaluated. Computer network threats are also examined in this thesis together with the network vulnerabilities and corresponding network security recommendations for these systems. Home users have a need for security and privacy being provided. There have been a number of recent security breaches affecting home users leading to mistrust among the users. Due to different classification of threats, there is a need for a common threat classification scheme that can help to improve the understanding of threats among different researchers. This thesis focuses on investigating possible vulnerabilities in a home network and consequently designing a vulnerability classification for home users.

Abstract:

This thesis describes a web-based application that will enable users to access their networked home appliances over the Internet in an easy, secured, accessible and cost effective manner, using the user's iris image only for authentication. As Internet is increasingly gaining significance and popularity in our daily lives, various home networking technologies also started gaining importance from consumers, which helped in facilitating interoperability, sharing of services and exchange of information between different electronic devices at home. As a result, the demand to be able to access home appliances or security cameras over the Internet gradually grew. In this research, we propose an efficient, secured, low-cost and user-friendly method to access networked home appliances over the Internet, providing strong, well integrated, three levels of security to the whole application and user data. According to our design, the user's iris data after hashing (using BioHashing) is sent through a secure communication channel utilizing Secure Sockets Layer v-3.0. The deterministic feature sequence from the iris image is extracted using 1D log-Gabor filters and while performing BioHashing, the orthonormalization of the pseudorandom number is implemented employing Gram-Schmidt orthonormalization algorithm. In addition to this protected data transfer mechanism, we propose the design of an Authentication Server that can be shared among multiple homes, allowing numerous users to access their home appliances in a trouble-free and secured manner. It can also bring down the cost of commercial realization of this endeavor and increase its accessibility without compromising on system security. We demonstrate that the recognition efficiency of this system is computationally effective with equal error rate (EER) of 0% and 6.75% (average) in two separate conditions on CASIA 1 and CASIA 2 iris image datasets.

Abstract:

This dissertation is about the increasing technologization of domestic spaces and the implications for human-technology sociality that are ‘built-into’ ICT-enabled domestic spaces and technologies. Its central focus is the socio-cultural development of the networked home in terms of convergences of and between humans and technologies throughout the twentieth century. The dissertation considers electricity, automobility, and the informationalization of domestic spaces as necessary conditions for the emergence of the contemporary networked home. Acknowledging the broader context of changes in capitalism, the dissertation focuses upon sociotechnical change represented within ordinary and popular visions of domestic spaces that circulated in the late twentieth and early twenty-first centuries. To this end, it traces the long history of the networked home between 1906 and 2006 in two mass circulation magazines (and in appliance and home industry research materials between 1993 and 2008), and analyzes the advertisements, advice columns, and research reports contained therein. A framework drawn from social studies of technology, theories of the network society, and of consumption is used to address several broad questions: What are the implications of the scripted, built-in, and assumed characteristics of the relationships between humans and technologies in domestic spaces? What do these mean for the ways in which domestic spaces are configured? What lessons for the future of sociality between and among humans and technologies in and around domestic spaces might be taken from prior configurations? The hybrid sociality that is created by combinations of ICTs, domestic spaces and appliances, and human users relies upon ‘built-in’ scripts to function, layers of which – including the competences, skill sets, and preferred uses – become sedimented and help to facilitate the introduction, normalization, and domestication of novel technologies. By understanding how these built-in scripts have worked in technologized homes since 1906, this dissertation is an important step toward a sociological account of the next emerging trend in domestic technologies: those concerned with environmental sustainability.

Abstract:

La ricerca affronta il tema delle tecnologie digitali, con particolare attenzione alle tecnologie della connettività, considerandole una risorsa per l’attività progettuale. La profonda penetrazione delle ICT all’interno della nostra società ha consentito un massivo accesso all’informazione e alla comunicazione e, allo stesso tempo, ha contribuito a rendere meno netti i confini delle dinamiche che la animano. La ricerca si posiziona nell’ambito di indagine che il nuovo programma di ricerca europeo Horizon 2020 identifica come “Internet del futuro”, concentrandosi sull’Internet of Things ossia su ciò che riguarda gli oggetti intelligenti connessi. Attraverso la lente del design, focalizziamo l’attenzione sullo scenario applicativo domestico e personale. Prendiamo in considerazione aspetti che riguardano, soprattutto, l’esperienza della persona (benessere fisico, legami affettivi, legame con ‘l’esterno’, la gestione delle proprie risorse, ecc.) in relazione ad un ambiente domestico fortemente caratterizzato dalla presenza della rete. La ricerca ha come obiettivo generale quello di indagare il tema di come la diffusione delle tecnologie della connettività condiziona il progetto di artefatti e sistemi e, di conseguenza, come questo condiziona il lavoro del designer. Il nostro contributo, mediante l’impostazione di un framework progettuale, è teso alla promozione di una progettualità ‘consapevole’, che tenga in considerazione le peculiarità di questo ambito di lavoro, al fine di sviluppare soluzioni significative e sostenibili per le persone. La parte conclusiva della ricerca è orientata alla definizione dello scenario meta-progettuale “Linked-Home”, con l’intento di offrire possibili stimoli alle imprese che operano nei settori relativi alla casa. Il design ha allargato molto la propria area di attività, di studio e di influenza, così, riteniamo che, soprattutto nel caso del design di prodotto, i contenuti proposti possono stimolare designer e ricercatori a una riflessione sull’identità stessa di questo ambito della disciplina; la quale si sta arricchendo di nuovi significati, dovuti alla convergenza tra mondo fisico e digitale, al rapporto con l’elettronica, ai contenuti immateriali, all’importanza del servizio. The research deals with the issue of digital technologies, with a focus on technologies of connectivity, considering them an asset for design activity. The deep penetration of ICT, within our society, has given a massive access to information and communication but, at the same time, has contributed to blur the boundaries of the dynamics that animate the society itself. The contribution of this work is positioned in a research area, which the new european program Horizon 2020 identifies as “Future Internet”. We focus on the Internet of Things, actually on what concerns smart and connected objects. The research, through the lens of design, focuses on the last of these areas, dealing with aspects that concern, above all, the experience of the person (physical well-being, emotional bonds, connection to the ‘outside’, management of its own resources, and so on) in relation to a domestic environment strongly characterized by the presence of the network. The research has the overall aim to understand how to take advantage of the technology of connectivity: to guide the designer’s work and to offer a contribution (through new inputs) to the house’ sector companies. The aim of our contribution, through the setting of a design framework, is promoting an ‘aware’ kind of planning, which takes into consideration the features of this field of work, in order to develop meaningful and sustainable solutions for people. The concluding part of the research is aimed at defining the meta-design scenario “Linked-Home”. Through the scenario we attempt to offer a contribution (through new inputs) to the house’ sector companies, triggering actions of innovation. Design extended their own area of activity, study and influence, so, we think that, especially in the case of product design, the proposed contents can stimulate designers and researchers to reflect on the identity of this area of the discipline. This area, in fact, is being enriched with new meanings, due to the convergence of physical and digital worlds, the relationship with the electronics, the intangible elements and the importance of services.

Dissertação de Mestrado em Engenharia Electrotécnica e de Computadores
A evolução da banda larga e a introdução de novos equipamentos especializados em determinado tipo de serviço exigem a adopção de soluções inovadoras que permitam uma gestão e configuração rápida e flexível de acordo com as necessidades específicas de cada equipamento e cliente. A recente convergência de diversos serviços (voz, dados, wireless e televisão) num mesmo canal de acesso (Triple Play e Quadruple Play) e a profusão de aplicações têm dificultado a gestão, segurança e garantia do QoS (Quality of Service) nas redes, provocando assim a procura de novas soluções. Garantir a configuração, integridade e despiste de casos de avaria, são nesta altura grandes desafios para os sistemas de suporte à operação dos operadores. A PT Inovação dispõe de um sistema, o Network Activator, que é responsável pela mediação entre os sistemas de suporte à operação e os equipamentos da rede. Este trabalho apresenta um módulo de gestão de equipamentos baseado no recente protocolo de gestão remoto CWMP (CPE WAN Management Protocol), com o objectivo de um dia vir a ser integrado à plataforma da PT Inovação.

Abstract:

Home healthcare has been a growing sector of the economy over the last three decades with roughly 23,000 companies now doing business in the U.S. producing over $56 billion in combined annual revenue. As a highly fragmented market, profitability of individual companies depends on effective management and efficient operations. This dissertation aims at reducing costs and improving productivity for home healthcare companies. The first part of the research involves the development of a new formulation for the therapist routing and scheduling problem as a mixed integer program. Given the time horizon, a set of therapists and a group of geographically dispersed patients, the objective of the model is to minimize the total cost of providing service by assigning patients to therapists while satisfying a host of constraints concerning time windows, labor regulations and contractual agreements. This problem is NP-hard and proved to be beyond the capability of commercial solvers like CPLEX. To obtain good solutions quickly, three approaches have been developed that include two heuristics and a decomposition algorithm. The first approach is a parallel GRASP that assigns patients to multiple routes in a series of rounds. During the first round, the procedure optimizes the patient distribution among the available therapists, thus trying to reach a local optimum with respect to the combined cost of the routes. Computational results show that the parallel GRASP can reduce costs by 14.54% on average for real datasets, and works efficiently on randomly generated datasets. The second approach is a sequential GRASP that constructs one route at a time. When building a route, the procedure tracks the amount of time used by the therapists each day, giving it tight control over the treatment time distribution within a route. Computational results show that the sequential GRASP provides a cost savings of 18.09% on average for the same real datasets, but gets much better solutions with significantly less CPU for the same randomly generated datasets. The third approach is a branch and price algorithm, which is designed to find exact optima within an acceptable amount of time. By decomposing the full problem by therapist, we obtain a series of constrained shortest path problems, which, by comparison are relatively easy to solve. Computational results show that, this approach is not efficient here because: 1) convergence of Dantzig-Wolfe decomposition is not fast enough; and 2) subproblem is strongly NP-hard and cannot be solved efficiently. The last part of this research studies a simpler case in which all patients have fixed appointment times. The model takes the form of a large-scale mixed-integer program, and has different computational complexity when different features are considered. With the piece-wise linear cost structure, the problem is strongly NP-hard and not solvable with CPLEX for instances of realistic size. Subsequently, a rolling horizon algorithm, two relaxed mixed-integer models and a branch-and-price algorithm were developed. Computational results show that, both the rolling horizon algorithm and two relaxed mixed-integer models can solve the problem efficiently; the branch-and-price algorithm, however, is not practical again because the convergence of Dantzig-Wolfe decomposition is slow even when stabilization techniques are applied.
