摘要

The vehicular wireless ad hoc network (VANET), a specialised wireless sensor network, is booming to provide safety and comfort for passengers. Special features of VANET, such as high mobility nodes and large scale node population, make the quality of service (QoS) task extremely challenging. To provision quality of service (QoS) to traffic safety and entertainment applications in VANET, we propose a routing protocol which improves QoS of VANET in terms of delay, response time and throughput. The proposed scheme disseminates packets among the links which has longer expiration time calculated by using relative velocity vectors. The optimal routing path and a backup routing path are selected by balancing stability, cost and delay. Besides, the proposed scheme gracefully switches to a new optimal routing path before the current routing path broken. Simulation results indicate that the proposed protocol improves the bandwidth, routing duration, and response time.
