Research on Zone Routing Protocol Based on Bus Backbone Network
摘要
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.
