Abstract

In this paper, a multi-hop broadcast scheme called LDMB (Link-based Distributed Multi-hop Broadcast) is proposed to broadcast emergency messages efficiently in VANET (Vehicular Ad Hoc Network). The forwarding scheme in LDMB is completely distributed, where each vehicle who receives the emergency message estimates its link status firstly and then computes the waiting time before forwarding this message. LDMB does not need any handshakes and there may be several candidates to forward the message which guarantees the reliability of the multi-hop broadcast. Simulation results show that LDMB can have close performance in reliability but offer lower latency compared with other multi-hop broadcast protocols.
