Abstract: Dynamic source routing is not quick enough to adapt to fast-changing topology of the ad hoc network. To solve the problem, the paper gives the multipath protocol ideas, introduces a conception of adjacency information table, and presents a new protocol of Local Multi-Path Dynamic Source Routing(LMP-DSR). The protocol repairs the invalid route and shortens the detour route. Therefore, the packet loss rate and the average end-to-end delay are decreased. It is proved by the results of simulation experiment.

Key words: ad hoc network, dynamic source routing, adjacency information table, local multipath, network dynamic factor

摘要: 针对DSR协议在Ad Hoc网络拓扑结构频繁变化的情况下表现不佳的问题,借鉴多径路由协议思想,引入邻接信息表概念,改进DSR协议,给出一种局部多径动态源路由协议(LMP-DSR)。新协议能够及时修复失效路由,纠正路由绕远现象,从而降低了网络丢包率和平均端到端延迟。仿真结果表明,在节点快速移动的场景下,LMP-DSR协议的网络丢包率和平均端到端延迟明显低于DSR协议。
