摘要
DSR路由协议中很多相邻节点的"路由应答"无法到达源节点,因此向这些节点广播"路由请求"产生了不必要的耗费。如果选择相对于源节点移动性较弱的相邻节点进行"路由请求",则可比较稳定地获得"路由应答"。仿真结果显示,改进后的DSR(M-DSR)路由协议在路由发现时间、路由长度、路由错误、传播路由请求、路由应答等方面的性能较DSR路由协议有明显的改进。
Many routing responses of the contiguous nodes in the DSR routing protocol can not arrive at the resource nodes. So many unnecessary consumptions are produced when the source nodes broadcast routing requests to the contiguous nodes. Relatively steady routing responses can be acquired if the contiguous nodes, with less mobility than source nodes, are chosen to start the routing request. The simulation result shows that the modified DSR routing protocol has more improvement than DSR routing protocol in terms of route discovery time, routing length, routing error, propagating requests and route replies.
