摘要:

针对表驱动路由协议应用于城市交通环境时所造成的网络拥塞问题,提出一种改进的区域路由协议。根据公交车运行线路固定和速度稳定的特点,构建以公交车节点作为簇头节点、普通车节点作为簇内节点的簇,在此基础上将区域路由协议引入到公交车骨干网中,通过主动路由和按需路由方式促进车辆节点的数据传输。仿真结果表明,与无线自组网按需平面距离矢量路由协议、目的序号距离矢量协议相比,该路由协议具有更低的传输时延、丢包率及路由开销。

Abstract:

For the problem of network congestion caused by using table driven routing protocol in urban traffic,this paper proposes a modified Zone Routing Protocol(ZRP).It takes bus’s characteristics of constant speed and fixed rate into consideration,builds cluster by the rule that considering bus node as the head node of the cluster and ordinary car node as the intra-node of the cluster.On the basis,it establishes bus backbone network,and uses ZRP to promote the communication among the vehicle nodes by using active routing mode and on-demand routing mode.Simulation results show,compared with Ad Hoc On-demand Distance Vector Routing(AODV) protocol and Destination-sequenced Distance Vector(DSDV) protocol,the routing protocol has great improvement in transmission delay,packet loss rate and routing overhead.

Key words: Vehicular Ad Hoc Network(VANET), bus backbone network, Zone Routing Protocol(ZRP), transmission delay, packet loss ate, routing overhead
