Une architecture de contrôle de mobilité pour le routage de messages dans un réseau ad hoc de grande taille

Abstract : Ad hoc networks present the next great challenge for distributed systems research. Protocols that support communication in ad hoc networks have to take into account the mobility of the participants and the variation in the connectivity between associated parties. In fact, most research on routing algorithms in an ad hoc network is mainly based on algorithms dedicated to completely connected networks in which the node mobility is not used. In this thesis, we are interested on solutions which use mobility to improve routing performances. Some critical issues of routing in a large size ad hoc network are: inaccurate routing information about remote nodes, the connectivity and the protocol overhead. This thesis proposes a control mobility architecture to improve performances of the routing protocols in a large scale ad hoc network. We think that the node mobility represents an opportunity: if nodes move in an appropriate fashion, then routing algorithms can take advantage. Thus, our architecture with its rendez-vous mechanism try to reduce mobility and routing overhead. The use of the rendez-vous mechanism reduces energy consuption and node bandwidth, because the node transmission range can be reduced. We also present two algorithms, one fault tolerant in conjuction with simulations, tests and performances mesures. We also proved the feasibility of our solution by an implementation using real rebots.
