Vehicular ad hoc network (VANET) is a special class of wireless mobile communication network. For vehicle-to-vehicle (V2V) communication, suitable routing protocols are needed. A routing metric combining hop counts and retransmission counts at MAC layer is proposed with consideration of link quality and delay reduction. Based on the new routing metric, a cross-layer ad hoc on-demand multipath distance vector with retransmission counts metric (R-AOMDV) routing protocol is designed to make use of advantages of multi-path routing protocol, such as decrease of route discovery frequency. Compared with AOMDV with minimum hop-count metric, simulation results show that R-AOMDV achieves better performance with Pareto On/Off distribution traffic model in urban VANET, no matter in sparse or dense scenarios.
