Many of safety applications in Vehicular Ad hoc Networks (VANETs) are based on broadcast. Designing a broadcast protocol that satisfies VANET applications' requirements is very crucial. In this paper, a reliable and efficient multi-hop broadcast routing protocol for VANET is proposed. The proposed protocol provides the strict reliability in various traffic conditions. This protocol also performs low overhead by means of reducing rebroadcast redundancy in a high-density network environment. They show the performance analysis of the proposed protocol by simulation with ns-2 in different conditions, and give the simulation results demonstrating effectiveness of the proposed protocol compared with a simple flooding scheme. In section 2, they give a brief description of the related work and elaborate the contribution. Next in section 3, it is given the detailed description of the proposed protocol. Simulation results are presented in section 4. Finally, the conclusions are presented in Section 5.
