L'Internet des Objets (IdO) couvre peu à peu tous les aspects de notre vie. À mesure que ces systèmes deviennent plus répandus, le besoin de gérer cette infrastructure complexe comporte plusieurs défis. En effet, beaucoup de petits appareils interconnectés fournissent maintenant plus d'un service dans plusieurs aspects de notre vie quotidienne, qui doivent être adaptés à de nouveaux contextes sans l'interruption de tels services. Cependant, ce nouveau système informatique diffère des systèmes classiques principalement sur le type, la taille physique et l'accès des nœuds. Ainsi, des méthodes typiques pour gérer la couche logicielle sur de grands systèmes distribués comme on fait traditionnellement ne peuvent pas être employées dans ce contexte. En effet, cela est dû aux capacités très différentes dans la puissance de calcul et la connectivité réseau, qui sont très contraintes pour les appareils de l'IdO. De plus, la complexité qui était auparavant gérée par des experts de plusieurs domaines, tels que les systèmes embarqués et les réseaux de capteurs sans fil (WSN), est maintenant accrue par la plus grande quantité et hétérogénéité des logiciels et du matériel des nœuds. Par conséquent, nous avons besoin de méthodes efficaces pour gérer la couche logicielle de ces systèmes, en tenant compte les ressources très limitées. Cette infrastructure matérielle sous-jacente pose de nouveaux défis dans la manière dont nous administrons la couche logicielle de ces systèmes. Ces défis peuvent entre divisés en : Intra-nœud, sur lequel nous faisons face à la mémoire limitée et à la puissance de calcul des nœuds IdO, afin de gérer les mises à jour sur ces appareils ; Inter-noeud, sur lequel une nouvelle façon de distribuer les mises à jour est nécessaire, en raison de la topologie réseau différente et le coût en énergie pour les appareils alimentés par batterie ; En effet, la puissance de calcul limitée et la durée de vie de chaque nœud combiné à la nature très distribuée de ces systèmes, ajoute de la complexité à la gestion de la couche logicielle distribuée. La reconfiguration logicielle des nœuds dans l'Internet des objets est une préoccupation majeure dans plusieurs domaines d'application. En particulier, la distribution du code pour fournir des nouvelles fonctionnalités ou mettre à jour le logiciel déjà installé afin de l'adapter aux nouvelles exigences, a un impact énorme sur la consommation d'énergie. La plupart des algorithmes actuels de diffusion du code sur l'air (OTA) sont destinés à diffuser un microprogramme complet à travers de petits fragments, et sont souvent mis en œuvre dans la couche réseau, ignorant ainsi toutes les informations de guidage de la couche applicative. Première contribution : Un moteur de modèles en temps d'exécution représentant une application de l'IdO en cours d'exécution sur les nœuds à ressources limitées. La transformation du méta-modèle Kevoree en code C pour répondre aux contraintes de mémoire spécifiques d'un dispositif IdO a été réalisée, ainsi que la proposition des outils de modélisation pour manipuler un modèle en temps d'exécution. Deuxième contribution : découplage en composants d'un système IdO ainsi qu'un algorithme de distribution de composants efficace. Le découplage en composants d'une application dans le contexte de l'IdO facilite sa représentation sur le modèle en temps d'exécution, alors qu'il fournit un moyen de changer facilement son comportement en ajoutant/supprimant des composants et de modifier leurs paramètres. En outre, un mécanisme pour distribuer ces composants en utilisant un nouvel algorithme appelé Calpulli est proposé. / The Internet of Things (IoT) is covering little by little every aspect on our lives. As these systems become more pervasive, the need of managing this complex infrastructure comes with several challenges. Indeed, plenty of small interconnected devices are now providing more than a service in several aspects of our everyday life, which need to be adapted to new contexts without the interruption of such services. However, this new computing system differs from classical Internet systems mainly on the type, physical size and access of the nodes. Thus, typical methods to manage the distributed software layer on large distributed systems as usual cannot be employed on this context. Indeed, this is due to the very different capacities on computing power and network connectivity, which are very constrained for IoT devices. Moreover, the complexity which was before managed by experts on several fields, such as embedded systems and Wireless Sensor Networks (WSN), is now increased by the larger quantity and heterogeneity of the node’s software and hardware. Therefore, we need efficient methods to manage the software layer of these systems, taking into account the very limited resources. This underlying hardware infrastructure raises new challenges in the way we administrate the software layer of these systems. These challenges can be divided into: intra-node, on which we face the limited memory and CPU of IoT nodes, in order to manage the software layer and ; inter-node, on which a new way to distribute the updates is needed, due to the different network topology and cost in energy for battery powered devices. Indeed, the limited computing power and battery life of each node combined with the very distributed nature of these systems, greatly adds complexity to the distributed software layer management. Software reconfiguration of nodes in the Internet of Things is a major concern for various application fields. In particular, distributing the code of updated or new software features to their final node destination in order to adapt it to new requirements, has a huge impact on energy consumption. Most current algorithms for disseminating code over the air (OTA) are meant to disseminate a complete firmware through small chunks and are often implemented at the network layer, thus ignoring all guiding information from the application layer. First contribution: A models@runtime engine able to represent an IoT running application on resource constrained nodes. The transformation of the Kevoree meta-model into C code to meet the specific memory constraints of an IoT device was performed, as well as the proposition of modelling tools to manipulate a model@runtime. Second contribution: Component decoupling of an IoT system as well as an efficient component distribution algorithm. Components decoupling of an application in the context of the IoT facilitates its representation on the model@runtime, while it provides a way to easily change its behaviour by adding/removing components and changing their parameters. In addition, a mechanism to distribute such components using a new algorithm, called Calpulli is proposed.

Cyber-Physical Systems (CPS) have become one of the greatest research topics today; because they pose a new complex discipline, which addresses big existing and future systems as the Internet, the Internet of Things, sensors networks and smart grids. As a recent discipline, there are many possibilities to improve the state of the art, interoperability being one of the most relevant. Thus, this thesis has been created within the framework of interoperability for CPS, by using the SOS (Sensor Observation Service) standard, which belongs to the SWE (Sensor Web Enablement) framework of the OGC (Open Geospatial Consortium). It has been developed to give rise to a new line of research within the Distributed Real-Time Systems and Applications group (SATRD for its acronym in Spanish) from the Communications Department of the Polytechnic University of Valencia (UPV for its acronym in Valencian). The approach, with which the interoperability in the CPS has been addressed, is of synthetic type (from parts to whole), starting from a verifiable and workable solution for interoperability in sensor networks, one of the most significant CPSs because it is integrated in many other CPSs, next adapting and testing the solution in more complex CPS, such as the Internet of Things. In this way, an interoperability solution in sensor networks is proposed based on the SOS, but adapted to some requirements that makes of this mechanism a lighter version of the standard, which facilitates the deployment of future implementations due to the possibility of using limited devices for this purpose. This theoretical solution is brought to a first implementation, called SOSLite, which is tested to determine its characteristic behavior and to verify the fulfillment of its purpose. Analogously, and starting from the same theoretical solution, a second implementation is projected called SOSFul, which proposes an update to the SOS standard so that it is lighter, more efficient and easier to use. The SOSFul, has a more ambitious projection by addressing the Internet of Things, a more complex CPS than sensors networks. As in the case of the SOSLite, tests are performed and validation is made through a use case. So, both the SOSLite and the SOSFul are projected as interoperability solutions in the CPS. Both implementations are based on the theoretical proposal of a light SOS and are available for free and under open source licensing so that it can be used by the research community to continue its development and increase its use. / Los Sistemas Ciber-Físicos (CPS) se han convertido en uno de los temas de investigación con mayor proyección en la actualidad; debido a que plantean una nueva disciplina compleja, que aborda sistemas existentes y futuros de gran auge como: la Internet, la Internet de las Cosas, las redes de sensores y las redes eléctricas inteligentes. Como disciplina en gestación, existen muchas posibilidades para aportar al estado del arte, siendo la interoperabilidad uno de los más relevantes. Así, esta tesis se ha creado en el marco de la interoperabilidad para los CPS, mediante la utilización del estándar SOS (Sensor Observation Service) perteneciente al marco de trabajo SWE (Sensor Web Enablement) del OGC (Open Geospatial Consortium). Se ha desarrollado para dar surgimiento a una nueva línea de investigación dentro del grupo SATRD (Sistemas y Aplicaciones de Tiempo Real Distribuidos) del Departamento de Comunicaciones de la UPV (Universitat Politècnica de València). La aproximación con la cual se ha abordado la interoperabilidad en los CPS es de tipo sintética (pasar de las partes al todo), iniciando desde una solución, verificable y realizable, para la interoperabilidad en las redes de sensores, uno de los CPS más significativos debido a que se integra en muchos otros CPS, y pasando a adaptar y comprobar dicha solución en CPS de mayor complejidad, como la Internet de las Cosas. De esta forma, se propone una solución de interoperabilidad en las redes de sensores fundamentada en el SOS, pero adaptada a unos requerimientos que hacen de este mecanismo una versión más ligera del estándar, con lo que se facilita el despliegue de futuras implementaciones debido a la posibilidad de emplear dispositivos limitados para tal fin. Dicha solución teórica, se lleva a una primera implementación, denominada SOSLite, la cual se prueba para determinar su comportamiento característico y verificar el cumplimiento de su propósito. De forma análoga y partiendo de la misma solución teórica, se proyecta una segunda implementación, llamada SOSFul, la cual propone una actualización del estándar SOS de forma que sea más ligero, eficiente y fácil de emplear. El SOSFul, tiene una proyección más ambiciosa al abordar la Internet de las Cosas, un CPS más complejo que las redes de sensores. Como en el caso del SOSLite, se realizan pruebas y se valida mediante un caso de uso. Así, tanto el SOSLite como el SOSFul se proyectan como soluciones de interoperabilidad en los CPS. Ambas implementaciones parten de la propuesta teórica de SOS ligero y se encuentran disponibles de forma gratuita y bajo código libre, para ser empleados por la comunidad investigativa para continuar su desarrollo y aumentar su uso. / Els sistemes ciberfísics (CPS, Cyber-Physical Systems) s'han convertit en un dels temes de recerca amb major projecció en l'actualitat, a causa del fet que plantegen una nova disciplina complexa que aborda sistemes existents i futurs de gran auge, com ara: la Internet, la Internet de les Coses, les xarxes de sensors i les xarxes elèctriques intel·ligents. Com a disciplina en gestació, hi ha moltes possibilitats per a aportar a l'estat de la qüestió, sent la interoperabilitat una de les més rellevants. Així, aquesta tesi s'ha creat en el marc de la interoperabilitat per als CPS, mitjançant la utilització de l'estàndard SOS (Sensor Observation Service) pertanyent al marc de treball SWE (Sensor Web Enablement) de l'OGC (Open Geospatial Consortium). S'ha desenvolupat per a iniciar una nova línia de recerca dins del Grup de SATRD (Sistemes i Aplicacions de Temps Real Distribuïts) del Departament de Comunicacions de la UPV (Universitat Politècnica de València). L'aproximació amb la qual s'ha abordat la interoperabilitat en els CPS és de tipus sintètic (passar de les parts al tot), iniciant des d'una solució, verificable i realitzable, per a la interoperabilitat en les xarxes de sensors, un dels CPS més significatius pel fet que s'integra en molts altres CPS, i passant a adaptar i comprovar aquesta solució en CPS de major complexitat, com la Internet de les Coses. D'aquesta forma, es proposa una solució d'interoperabilitat en les xarxes de sensors fonamentada en el SOS, però adaptada a uns requeriments que fan d'aquest mecanisme una versió més lleugera de l'estàndard, amb la qual cosa es facilita el desplegament de futures implementacions per la possibilitat d'emprar dispositius limitats a aquest fi. Aquesta solució teòrica es porta a una primera implementació, denominada SOSLite, que es prova per a determinar el seu comportament característic i verificar el compliment del seu propòsit. De forma anàloga i partint de la mateixa solució teòrica, es projecta una segona implementació, anomenada SOSFul, que proposa una actualització de l'estàndard SOS de manera que siga més lleuger, eficient i fàcil d'emprar. El SOSFul té una projecció més ambiciosa quan aborda la Internet de les Coses, un CPS més complex que les xarxes de sensors. Com en el cas del SOSLite, es realitzen proves i es valida mitjançant un cas d'ús. Així, tant el SOSLite com el SOSFul, es projecten com a solucions d'interoperabilitat en els CPS. Ambdues implementacions parteixen de la proposta teòrica de SOS lleuger, i es troben disponibles de forma gratuïta i en codi lliure per a ser emprades per la comunitat investigadora a fi de continuar el seu desenvolupament i augmentar-ne l'ús. / Pradilla Ceron, JV.

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

This qualitative study evaluates what the Internet of Things (IoT) can bring to create benefits in municipal housing companies. Since 2014, there has been a guide from the Swedish Agency for Digital Administration regarding benefits realization that describes how organizations can work to implement IT projects and realize target images, by focusing on the underlying benefits. The issues that this study focuses on are benefits and expectations from completed IoT projects. To answer these questions, five interviews and a pilot study, based on a framework for benefit realization, were conducted with people representing a large number of municipalities in Sweden. The respondents have had good insight into how the operations work in the IoT technology area. The main conclusion of the study is that the work with benefits, has a small role in the organizations consulted. Many of the obstacles identified in the study show that active management is required to change the culture around IoT projects and that the business focuses on the benefits behind the IoT solutions rather than the artifacts themselves. Previous research has shown that IoT is a disruptive innovation, which requires new thinking and other types of skills. Most organizations have built up their own infrastructures with pre-packaged services that have been offered to the businesses in order to create interest and let the businesses themselves discover the benefits that the technology can bring. / I den här kvalitativa studien utvärderas vad Internet of Things (IoT) kan tillföra för att skapa nytta i kommunala bostadsbolag. Sedan 2014 finns det en guide från Myndigheten för digital förvaltning i nyttorealisering, som är ett stöd i hur organisationer kan arbeta för att genomföra IT-projekt och realisera målbilder, genom att fokusera på den bakomliggande nyttan. De frågor som denna studie fokuserar på är nyttor och förväntningar från genomförda IoT-projekt. För att besvara dessa frågor har fem intervjuer och en pilotstudie, utifrån ett ramverk för nyttorealisering, genomförts med personer som representerar ett stort antal kommuner i Sverige. Respondenterna har haft god insikt i hur verksamheterna arbetar inom teknikområdet IoT.   Studiens främsta slutsats är att arbetet med nyttor, har en liten roll i de organisationer som tillfrågats. Många av de hinder som identifierats i studien visar på att det krävs en aktiv styrning för att förändra dels kulturen kring IoT-projekt och dels att verksamheten fokuserar på nyttan bakom IoT-lösningarna snarare än själva artefakterna. Tidigare forskning har visat att IoT är en disruptiv innovation vilket kräver nytänkande och andra typer av kompetenser. De flesta organisationer har byggt upp egna infrastrukturer med färdigpaketerade tjänster som erbjudits verksamheterna i syfte att skapa intresse och låta verksamheterna själva upptäcka de nyttor som tekniken kan tillföra.

[pt] A ideia principal da Internet das Coisas (IoT) é conectar bilhões de coisas à Internet nos próximos anos, a exemplo de carros, roupas e comidas. Entretanto, muitos problemas precisam ser resolvidos antes que essa ideia possa ser concretizada. Alguns desses problemas estão relacionados à necessidade de construir sistemas para IoT que sejam auto-organizáveis e autoadaptativos. Este trabalho, portanto, apresenta a elaboração do Framework para Internet das Coisas (FIoT), que oferece suporte ao desenvolvimento de aplicações para IoT com essas características. Ele é baseado nos paradigmas de Sistemas Multiagente (SMA) e algumas técnicas abordadas em Aprendizado de Máquina, a exemplo de redes neurais e algoritmos evolutivos. Um agente pode ter algumas características, como autonomia e sociabilidade, que tornam SMAs compatíveis com sistemas que requerem auto-organização. Redes neurais e algoritmos de evolução vêm sendo comumente usados nos estudos de robótica, no intuito de prover autonomia e adaptação à agentes físicos (ex.: robôs, sensores). Para demonstrar o uso do FIoT, dois grupos de problemas em IoT serão instanciados: (i) Cidades Inteligentes e (ii) Quantificação de Coisas. / [en] The agreed fact about the Internet of Things (IoT) is that, within the coming years, billions of resources, such as cars, clothes and foods will be connected to the Internet. However, several challenging issues need to be addressed before the IoT vision becomes a reality. Some open problems are related to the need of building self-organizing and self-adaptive IoT systems. To create IoT applications with these features, this work presents a Framework for Internet of Things (FIoT). Our approach is based on concepts from Multi-Agent Systems (MAS) and Machine Learning Techniques, such as a neural network and evolutionary algorithms. An agent could have characteristics, such as autonomy and social ability, which makes MAS suitable for systems requiring self-organization (SO). Neural networks and algorithms of evolution have been commonly used in robotic studies to provide embodied agents (as robots and sensors) with autonomy and adaptive capabilities. To illustrate the use of FIoT, we derived two different instances from IoT applications: (i) Quantified Things and (ii) Smart Cities. We show how exible points of our framework are instantiated to generate an application.

Internet of things är idag en utveckling som starkt går framåt för att göra samhället mer tekniskt styrt, modernt och för att underlätta för människor. Det finns många branscher och arbetsområden för denna teknik och hissbranschen är en utav dessa. I denna rapport utreds de fördelar som finns med Internet of things inom hissövervakning. Företaget Safeline Sweden AB har tagit fram en produkt för att underlätta övervakningen av hissar på avstånd. En utredning av denna produkt och dess kostnadsfördelar togs fram, för att sedan kunna ta fram en affärsmodell för Safelines nya produkt IMS. Genom intervjuer med potentiella kunder kunde information tas fram angående dagens läge inställningen till ny teknik. Den informationen som kom fram under dessa intervjuer användes för att skapa en affärsmodell som ska användas som grund för en affärplan för Safeline.En affärsmodell skapades för Safeline Sweden AB och deras nya produkt IMS. I affärmodellen framgår det bland annat hur företaget bör lansera den nya produkten, hur kundrelationer ska skapas, utvecklas och behållas. Utifrån intervjuerna valdes det att IMS bör säljas som en systemlösning då det anses vara det bästa för att det ska vara attraktivt och prisvärt för kunderna. / Internet of things is today a development that is strongly moving forward to make society more con-trolled by technology, modern and it will be easier for many people. This technology can be used in many diffrent industries and work areas, such as elevator monitoring. This report evaluates the benefits with Internet of things within elevator monitoring. The company Safeline Sweden AB has developed a product that will make it easier to monitor elevators from a distance. An investigation of this product has been done and what their advantages were. After that, a buisness model was formed for Safelines new product IMS. By interviewing potential customers, the information about the sitaution today and the approach for new technology was discovered. The information from the interviews was then used to create a good and sustainable business model for Safeline.A buisness model was created for Safeline Sweden AB and the produkt IMS. The business model describes how the company should launch the new product, how the customer relations should be created, developed and retained. The information from the interviews made it clear that the IMS should be sold as a system solution because it is considered to be more attractive and be more valu-able for the customers.

As an essential and indispensable contributor to pollinating the world's crops and plants, the honey bee is key to the sustainability of humans' and our ecosystems' continued survival. Following in the footsteps of the companies TietoEvry and Beelabs project, this report also works towards monitoring bees during their daily activities. This project aims to investigate the feasibility of using wireless, battery-driven devices inside beehives to detect the sound of bees using machine learning for edge devices. Beelab has focused on measurements in and around the beehive regarding weight, temperature, barometric pressure and humidity. Sound analysis is still in its infancy with few finished working alternatives; therefore, this project will focus on the sound attribute by implementing machine learning and classification algorithms and applying it to a prototype—the progress is thoroughly documented in this report. The device records a snippet of sound and prepares to send it over a wireless transmission medium. By streamlining the code and optimizing the hardware, the device runs continuously for a month using a small, cheap battery.

With an increasing number of people currently living in urban areas, many cities around the globe are faced with issues such as increased pollution and traffic congestion. In an effort to tackle such challenges, governments and city councils are formulating new and innovative strategies. The integration of ICT with these strategies creates the concept of smart cities. The Internet of Things (IoT) is a key driver for smart city initiatives, making it necessary to have an IT infrastructure that can take advantage of the many benefits that IoT can provide. The Cloudlet is a new infrastructure model that offers cloud-computing capabilities at the edge of the mobile network. This environment is characterized by low latency and high bandwidth, constituting a novel ecosystem where network operators can open their network edge to third parties, allowing them to flexibly and rapidly deploy innovative applications and services towards mobile subscribers. In this thesis, we present a cloudlet architecture that leverages edge computing to provide a platform for IoT devices on top of which many smart city applications can be deployed. We first provide an overview of existing challenges and requirements in IoT systems development. Next, we analyse existing cloudlet solutions. Finally, we present our cloudlet architecture for IoT, including design and a prototype solution. For our cloudlet prototype, we focused on a micro-scale emission model to calculate the CO2 emissions per individual trip of a vehicle, and implemented the functionality that allows us to read CO2 data from CO2 sensors. The location data is obtained from an Android smartphone and is processed in the cloudlet. Finally, we conclude with a performance evaluation. / Med en befolkning som ökar i urbana områden, står många av världens städer inför utmaningar som ökande avgaser och trafikstockning. I ett försök att tackla sådana utmaningar, formulerar regeringar och stadsfullmäktige nya och innovativa strategier. Integrationen av ICT med dessa strategier bildar konceptet smart cities. Internet of Things (IoT) är en drivande faktor för smart city initiativ, vilket gör det nödvändigt för en IT infrastruktur som kan ta till vara på de många fördelar som IoT bidrar med. Cloudlet är en ny infrastrukturell modell som erbjuder datormolnskompetens i mobilnätverkets edge. Denna miljö karakteriseras av låg latens och hög bandbredd, utgörande ett nytt ekosystem där nätverksoperatörer kan hålla deras nätverks-edge öppet för utomstående, vilket tillåter att flexibelt och snabbt utveckla innovativa applikationer och tjänster för mobila subskribenter. I denna avhandling presenterar vi en cloudlet-arkitektur som framhäver edge computing, för att förse en plattform för IoT utrustning där många smart city applikationer kan utvecklas. Vi förser er först med en överblick av existerande utmaningar och krav i IoT systemutveckling. Sedan analyserar vi existerande cloudlet lösningar. Slutligen presenteras vår cloudlet arkitektur för IoT, inklusive design och en prototyplösning. För vår cloudlet-prototyp har vi fokuserat på en modell av mikroskala för att räkna ut CO2 emissioner per enskild resa med fordon, och implementerat en funktion som tillåter oss att läsa CO2 data från CO2 sensorer. Platsdata är inhämtad med hjälp av en Android smartphone och behandlas i cloudlet. Det hela sammanfattas med en prestandaevaluering.

Urbanization has been a growing trend in the past fifty years. Cities are now transforming into smart cities, spaces whose infrastructure comprises an embedded digital layer. Hardware collects real-time data in the urban environment and software elaborates it to improve all types of services, from traffic to waste management to well-being. One technology that is expected to use this digital layer to further change the urban environment is the autonomous car. The purpose of this dissertation is to explore what key design attributes future autonomous cars should possess if they have not only to co-exist with and be accepted by people in the landscape of tomorrow’s smart cities, but also what they should not possess in order not to cause any harm. In this sense, the dissertation recognizes calm technology to be necessary in the design of a future autonomous car to support a human-centered, as opposed to a car- or technology-centered, environment. A socio-technical and systemic lens is applied to the phenomenological investigation of nine companies carried out by means of twelve in-depth semi-structured interviews with experts working within the automotive sector, the smart city industry, and calm technology. Eight attributes (safety, on-demand, geo-tracking, sharing, multiple purposes, communication through smart devices, electrical care and IoT/connectedness) are identified as necessary for future autonomous cars to implement in order to take advantage of the smart city infrastructure and provide a human-centered experience. Additionally, six out of the eight calm technology principles recognized in literature are considered necessary when designing future autonomous cars.

L'Internet des Objets ou en anglais the Internet of Things (IoT) représente aujourd'hui une partie majeure de notre vie quotidienne. Des milliards d'objets intelligents et autonomes, à travers le monde sont connectés et communiquent entre eux. Ce paradigme révolutionnaire crée une nouvelle dimension qui enlèveles frontières entre le monde réel et le monde virtuel. Son succès est dû à l’évolution des équipements matériels et des technologies de communication notamment sans fil. L’IoT est le fruit du développement et de la combinaison de différentes technologies. Il englobe presque tous les domaines de la technologie d’information (Information Technology (IT)) actuels.Les réseaux de capteurs sans fil représentent une pièce maîtresse du succès de l'IoT. Car en utilisant des petits objets qui sont généralement limités en terme de capacité de calcul, de mémorisation et en énergie, des environnements industriels, médicaux, agricoles, et autres peuvent être couverts et gérés automatiquement.La grande puissance de l’IoT repose sur le fait que ses objets communiquent, analysent, traitent et gèrent des données d’une manière autonome et sans aucune intervention humaine. Cependant, les problèmes liés à la sécurité freinent considérablement l’évolution et le déploiement rapide de cette haute echnologie. L'usurpation d’identité, le vols d’information et la modification des données représentent un vrai danger pour ce système des systèmes.Le sujet de ma thèse consiste en la création d'un système de sécurité permettant d’assurer les services d’authentification des objets connectés, d’intégrité des données échangées entres ces derniers et de confidentialité des informations. Cette approche doit prendre en considération les contraintes des objets et des technologies de communication utilisées. / Internet of Things becomes a part of our everyday lives. Billions of smart and autonomous things around the world are connected and communicate with each other. This revolutionary paradigm creates a new dimension that removes boundaries between the real and the virtual worlds. Its success is due to the evolution of hardware and communication technologies, especially wireless ones. IoT is the result of the development and combination of different technologies. Today, it covers almost all areas of information technology (IT).Wireless sensor networks are a cornerstone of IoT's success. Using constrained things, industrial, medical, agricultural, and other environments can be automatically covered and managed.Things can communicate, analyze, process and manage data without any human intervention. However, security issues prevent the rapid evolution and deployment of this high technology. Identity usurpation, information theft, and data modification represent a real danger for this system of systems.The subject of my thesis is the creation of a security system that provides services for the authentication of connected things, the integrity of their exchanged data and the confidentiality of information. This approach must take into account the things and communication technologies constraints.
