CoFFee: Cooperative and inFrastructure-Free peer-to-peer system for VANET

Peer-to-peer systems in vehicular ad hoc networks are the scope of intensive research in last few years. Several proposed content sharing systems in the literature are based on a hybrid infrastructure containing static gateways that manage the file sharing between the vehicles. In this paper, we present CoFFee, a Cooperative and inFrastructure-Free peer-to-peer system, where the network do not rely on a preexisting infrastructure. The cooperative behavior of the nodes during the file sharing process is the main contribution of CoFFee. We evaluated CoFFee using OMNET++ simulation environment. The first simulation results when applying our content distribution algorithm are very promising.
