Abstract

With the increasing of vehicular wireless communication, vehicle Ad hoc networks(VANETs) have become an important part of the intelligent transportation system. Based on the multi-channel MAC protocol in VANETs, this paper proposed a backoff algorithm for different nodes considering fairness of network. By comparing the successful sending traffic throughput of the node and the average traffic throughput for its neighbors, the node determined backoff windows so that to improve the fairness in accessing process. In order to improve the fairness of network, the algorithm sacrificed amount of traffic throughput. Noticed that the service channels were not saturated, this paper also proposed an algorithm to adjust the length of service reservation period based on node density. The algorithm improved the utilization of service channels and the throughput of network. Simulation results indicated that comparing with the BEB algorithm and the MILD algorithm, the proposed backoff algorithm can effectively improve fairness of network by 2.3 times and 2.05 times, respectively. Meanwhile, the adjusting algorithm can significantly improve the network throughput by 16%.
