Résumé

The increasing interest in vehicular communications draws attention to scalability and network congestion problems and therefore on techniques to offload the traffic, typically carried through the infrastructure, to the Vehicle-to-vehicle (V2V) network. Floating content (FC) represents a promising paradigm to share ephemeral content without direct support from infrastructure. It is based on constraining geographically within the Anchor Zone (AZ), the opportunistic replication of a given content among vehicles, in a way that strikes a balance between minimization of resource usage and content availability to users within the AZ. This paper constitutes a first attempt at addressing the issue of how to control FC performance in a realistic vehicular setting. It proposes a set of strategies for tuning the size of the AZ, based on the estimation of some key mobility parameters and of target FC performance.
