In vehicular ad hoc network (VANET), a single-hop transmission is usually unable to cover all the intended receivers due to the limited radio range. Therefore, multi-hop broadcast services should be supported and then the next hop selection becomes a critical problem. However, conventional broadcast routing schemes cannot promise a good enough reliability and efficiency for VANET. In this paper, we propose a reliable broadcast routing scheme based on mobility prediction (RB-MP) to achieve an efficient multi-hop broadcast. This scheme selects the reliable and efficient rebroadcast nodes, according to the prediction holding time provided by position and relative velocity. Our proposed scheme is analyzed in several scenarios compared with other broadcast routing protocols. Finally, the simulation results show that the proposed scheme has better performance in terms of the packet delay and efficiency percentage.
