摘　　要：针对DSR路由协议路由发现过程速度慢的不足,提出了一种可自扩展的DSR路由协议——IDSR协议,并与传统的DSR协议的性能指标进行了分析和比较。该协议通过限制DSR的路由请求过程中对全网络洪泛的机制,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,使其具有自扩展功能。仿真结果表明该协议的基本性能指标要好于传统DSR协议的。According to the DSR route protocol insufficiency： the slow speed in route discovery process. The expansion DSR route protocol--IDSR protocol is proposed. The performance index with the traditional DSR protocol is analyzed and compared. The protocol through limits DSR in the route request process to the entire network flooding mechanism, requested the route scope to limit in certain region, then cascade expansion request scope fi＇om the actual situation, enable it to have the expansion function. The simulation result indicated that the basic performance index of the protocol would be better then the traditional DSR protocol
