摘　　要：基于车载通信网的运动规律,提出一种车载通信网中基于分群机制的常驻代理网络拓扑发现策略(VCBRP),并给出了相应的分群算法.计算机仿真实验表明,VCBRP算法具有更强的负载均衡特性,在高速环境下具有更低的时延和路由请求次数,包的提交率也有一定程度的提高.The authors analyzed the movement characteristics of vehicular communication network;proposed a cluster-based network topology discovery strategy with resident agent in vehicular communications network（VCBRP）;and provided the corresponding clustering algorithm.The proposed VCBRP protocol was compared with CBRP and DSR protocols through computer simulations.Simulation results show that VCBRP algorithm has better performance in terms of load balancing,with lower end to end transmission delay and less route request times in high-speed environment,and the packet delivery rate has improved to some extent.
