Résumé en françaisL'objectif de cette thèse est de proposer une approche permettant de traiter le problème de l'hétérogénéité des technologies de réseaux sans fil et des protocoles associés dans un environnement pervasif. Les travaux à réaliser mettront plus particulièrement l'accent sur la conception d'un intergiciel dédié qui sera responsable à la fois de sa propre reconfiguration dynamique et de celle de la plate-forme matérielle sous-jacente (radio matérielle/logicielle reconfigurable), ceci afin de permettre le déploiement de nouveaux services.Description
The phenomenal growth of low-cost, lightweight, portable computers together with the advances in wireless networking technologies are making ubiquitous computing a reality. Network communication between heterogeneous entities is required in a wide range of embedded systems from various application domains such as building automation, assisted living and mobile personal computing. Unfortunately, however, the devices used in these domains are highly heterogeneous in terms of both hardware and software. Traditionally, because of their highly constrained resources embedded systems provide a limited set of wireless networking technologies and support few application protocols. This hardware and software heterogeneity limits communication capabilities of such devices and segregates an embedded system from the outside world, preventing it from capitalizing on existing services and devices. To overcome these issues, gateways distributed throughout a pervasive environment are needed to translate between the various protocols. However, the volatile and evolving nature of pervasive environments requires these gateways to be dynamically reconfigured according to the wireless networking technologies and protocols used by the devices available at a given time. Hardware reconfiguration of gateway becomes possible thanks to recent work on reconfigurable hardware systems and software defined radio technologies. However, a reconfigurable middleware is still required to dynamically update translation services and manage underlying hardware reconfiguration.The goal of this PhD is to propose an approach to address the problem of supporting the heterogeneity of wireless networking technologies and protocols in a pervasive environment. The research work will more specifically focus on the design of a dedicated middleware that will be responsible for dynamically reconfiguring itself and the underlying hardware platform according to the new service being deployed. Before performing its reconfiguration, the middleware will check that the new service being deployed is compatible (e.g., in hardware) with already deployed services and will not compromise overall performance of the system. Concrete applications will be explored in the context pervasive environments that require dynamic update of the services made available to networked devices.
