Abstract:The vehicular ad hoc networks(VANETs) presents the uneven node density, fast moving speed,dynamic topology change etc.In order to improve the reliability of VANETs in information broadcasting, and reduce the redundancy of multi-hop broadcast, a protocol based on the clustering position-competition of vehicular ad hoc networks is proposed. Furthermore the concept of connectivity-stability is introduced.In the paper, The road is divided into segment model and intersection model.The cluster head and the optimal nodes in the cluster are chose as a radio relay nodes, which reduces the broadcast redundancy and improves the broadcast efficiency.At the same time, for the isolated nodes in the network ,carry-forwarding method is taken ,which improves the broadcast reliability in sparse areas and in "hole" areas.Finally, we use the NS2 simulation tool to.The simulation results show that the proposed routing protocol has a better comprehensive performance in delivery success rate, average broadcast time delay and the broadcast overhead. | |||
