| 摘 要： | 分析了现有动态源路由(dynamic source routing,DSR)协议机制以及在车载通信网路由发现中存在的问题,提出一种基于DSR分层机制的移动代理路由策略(cluster mobile agent-dynamic source routing,CM-DSR),并对设计的算法进行仿真实验。结果表明,所提出的CM-DSR协议与DSR路由协议相比较,较大幅度地降低了端到端的传输延迟,减少了路由请求次数,包的提交率也有一定程度的提高。

| Abstract: | In this paper,we analyzed the existing mechanisms of DSR routing protocol and the routing discovery problem especially existed in Vehicle Communication Network.Moreover,we proposed a mobile agent routing strategy(Cluster Mobile agent-Dynamic Source Routing,CM-DSR)based on DSR stratification mechanism,we also conducted a simulation experiment on our algorithm.Extensive simulation results showed that the proposed CM-DSR protocol compared to DSR routing protocol can reduce significantly the end to end transmis... |
