对DSR路由协议的路由选择和缓存策略进行分析,并针对它的不足,提出通过引入时间参数对路由的选择进行限制,采用自适应路由缩短机制的改进协议。新笨略不但提高了缓冲器中路由的质量,而且充分利用了路由缓冲器的空间。利用NS2进行仿真,结果显示对DSR路由协议进行优化后,比较明显地改进了DSR路由协议的性能。
This paper analyzes the strategies of choosing and caching in DSR and presents the improved protocol which uses the parameter of time to limit the choosing of routing and adopt the adaptive automation route shorting, The new strategies not only can use the buffer volume more efficient, but also improve the quality of route. Simulation results by NS2 show that the proposed techniques improve the performance of DSR obviously.
