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.
