无线Ad hoc网络中DSR协议的多路探测和定时算法改进

An Observation of Multi-way and Improvement of Calculating with Setting Time of DSR Agreement of at Wireless Ad Hoc of Net

无线Ad hoc网络拓扑结构频繁变化导致DSR缓存中的路由信息过期,过期路由的使用导致信息传输的失败。文章在动态源路由协议(Dynamic Source Routing,简称DSR)的基础上提出了多路探测和定时机制的路由协议(Multi-Probing and Time-out Dynamic Source Routing,MPTDSR),该协议通过定时地主动探测路径的有效性从而清除缓存中的过期路由,主动更新缓存。实验结果表明,在数据的传输率、传输延时、路由开销等方面均优于基于路由缓存的DSR协议。

the information is expired with changing of complex topological structure of wireless ad hoc.The paper motioned the Multi-Probing and Time-out Dynamic Source Routing based on Dynamic Source Routing for updating assuasive store. The results of experiment also proofed.
