In this paper, we propose a distributed mobility transparent broadcast (DMTB) protocol to achieve efficient and effective broadcasts in vehicle-to-vehicle networks. The protocol is fully distributed and highly adaptive to node mobility. Although distributed, DMTB does not suffer from the performance degradation induced by the unavailability of global information. The protocol's performance is proven to be within a constant of the optimum. A detailed analysis regarding the protocol's performance is presented. The simulation results clearly verify that the protocol maintains its performance under high node mobility.
