Partage d’informations dans les réseaux de communication inter-véhiculaire

Abstract : This thesis is interested in the information sharing in inter-vehicle communication networks. Today, thanks to the positioning systems and to the wireless communication capacities, vehicles can exchange data relating different kind of events (emergency brake, traffic jam, available parking spot, etc.) in order to provide new assistance systems for the drivers. In this work, we focused on vehicle-to-vehicle communication (V2V). The absence of any fixed communication infrastructure and the high nodes' mobility (i.e. vehicles) in the network raise particularly interesting problems in term of data management, for example, in term of relevance estimation in these particularly dynamic environments. In this context, our main contributions concern : the proposal of mechanisms, based on the computation of an encounter probability, allowing to estimate the relevance of information exchanged between vehicles ; mechanisms of continuous query processing in decentralized environments allowing to keep information updated ; a dissemination protocol, exploiting our encounter probability, allowing to route data to vehicles potentially interested. Our proposals were evaluated in the VESPA (Vehicular Event Sharing with a mobile Peer-to-peer Architecture) system as well as through numerous simulations.
