摘要： 针对动态源路由(DSR)协议在Ad Hoc网络拓扑结构频繁变化时表现欠佳的问题，在DSR协议的基础上引入邻接信息表概念，提出基于邻接信息表的动态源路由协议AIT-DSR。该协议可以加速路由发现，纠正路由绕远，规避高负载节点，快速修复失效路由，降低网络丢包率和平均端到端延时。仿真结果表明，在节点快速移动的场景下，AIT-DSR协议的丢包率和平均端到端延时低于DSR协议。

Abstract: Dynamic Source Routing(DSR) protocol is not quick enough to adapt to fast-changing topology of Ad Hoc network. To solve the problem, this paper introduces a conception of adjacency information table, presents a new protocol of DSR based on Adjacency Information Table(AIT-DSR). The protocol accelerates the route discovering, shortens the route, repairs the invalid route and avoids the high-load node. The packet loss rate and the average end-to-end delay decrease. It is proved by the results of simulation experiment.
