A Remediable Broadcasting Protocol for Vehicular Ad hoc Network

In this paper, a novel cross-layer and distance-based broadcasting protocol called as Remediable Broadcasting Protocol (RBP) has been proposed to avoid the Broadcast Storm in Vehicular Ad hoc Network(VANET). In RBP, some potential forwarders greedily contend to retransmit the packets and the protocol elects the forwarders as quickly as possible without considering the redundant retransmission temporarily. When the winner sends the packet successfully, the retransmissions of other candidate forwarders will be cancelled or the packets which send to the sending queue by the candidate forwarders will be deleted to reduce the broadcast redundancy efficiently. Simulation results show that the protocol is better than others in reachability, saved rebroadcast, dissemination rate and single-hop packet reception ratio.
