The Internet of Things paradigm establishes interaction and communication with a huge amount of actors. The concept is not a new-from-scratch one; actually, it combines a vast number of technologies and protocols and surely adaptations of pre-existing elements to offer new services and applications. One of the key technologies of the Internet of Things is the Radio Frequency Identification just abbreviated RFID. This technology proposes a set of solutions that allow tracking and tracing persons, animals and practically any item wirelessly. Considering the Internet of Things concept, multiple technologies need to be linked in order to provide interactions that lead to the implementation of services and applications. The challenge is that these technologies are not necessarily compatible and designed to work with other technologies. Within this context, the main objective of this thesis is to design a heterogeneous framework that will permit the interaction of diverse devices such as RFID, sensors and actuators in order to provide new applications and services. For this purpose in this work, our first contribution is the design and analysis of an integration architecture for heterogeneous devices. In the second contribution, we propose an evaluation model for RFID topologies and an optimization tool that assists in the RFID network planning process. Finally, in our last contribution, we implemented a simplified version of the framework by using embedded hardware and performance metrics are provided as well as the detailed configuration of the test platform

Le paradigme de l'Internet des choses établit l'interaction et la communication avec une énorme quantité d'acteurs. Le concept combine un grand nombre de technologies et de protocoles et des adaptations des éléments préexistants pour offrir de nouveaux services et applications. Une des technologies clés de l'Internet des objets est l'identification par radiofréquence abrégée en anglais RFID («Radio Frequency Identification»). Elle propose un ensemble de solutions qui permettent le suivi et la traçabilité des personnes, des animaux et pratiquement n'importe quel objet en utilisant des liaisons sans fil. En considérant le concept de l'Internet des choses, plusieurs technologies doivent être liées afin de fournir des interactions qui conduisent à la mise en œuvre de services et d'applications. Le défi est que ces technologies ne sont pas nécessairement compatibles et conçues pour fonctionner ensemble. Dans ce contexte, l'objectif principal de cette thèse est de concevoir un « framework » hétérogène qui permettra l'interaction de divers dispositifs tels que la RFID, des capteurs et des actionneurs afin de fournir de nouvelles applications et de services. À cet effet, notre première contribution est la conception et l'analyse d'une architecture d'intégration pour les dispositifs hétérogènes. Dans la seconde contribution, nous proposons un modèle d'évaluation de la topologie RFID et un outil d'optimisation pour la planification de réseaux de cette technologie. Enfin, nous avons implémenté une version simplifiée du framework en utilisant du matériel embarqué et indicateurs de performance sont fournis ainsi que la configuration détaillée de la plateforme de test / The Internet of Things paradigm establishes interaction and communication with a huge amount of actors.
