摘要
针对DSR路由协议中路由发现速度慢、网络冗余信息过多的不足,文中对现有DSR路由协议进行改进,使其限制了DSR路由请求过程中对全网络不必要的洪泛,并根据小世界理论模型把路由请求的范围限制在了一定的区域内,然后根据实际情况逐层扩大请求范围.在N S2平台下对该改进后的协议进行了仿真实验并与传统的DSR协议的性能进行了分析和比较,仿真结果表明该协议的基本性能指标要优于传统DSR协议.
The insufficiency of the DSR Protocol is the slow speed in Route Discovery Process and overabundance of redundant information. The DSR Protocol is improved by limiting DSR in the Route Request process to the entire network Flooding mechanism, and requesting the route scope to limit in certain region, then cascading expansion request scope from the actual situation according to the mode of Small World. At last, simulation is carried out for the improved protocol on the NS2. The simulation result indicates that the basic performance index of the protocol is better than the traditional DSR Protocol.
