Abstract
The dissemination of information is the main application of vehicular networks. The cost of network data transmission is significantly increased and the overall performance of the network routing protocol is deteriorated obviously in the vehicle networks without cluster. In order to ensure the reliability and timeliness of information transmission in VANET, it is necessary to cluster the network in most cases. The existed clustering protocols cannot solve the problem of the stability of the cluster due to the high dynamic mobility in VANET. In this work, we improve a clustering protocol based on the optimization of number of cluster heads, the distance from cluster head to cluster members, and the relative velocity of vehicles within the cluster. The optimized cost function contains three weighting factors for adjusting the specific gravity. The weighting factors can be decided with different demand. Simulation results show that our improved clustering protocol has very good performance for the stability of the cluster. It can provide a good support for the future network routing protocol.
