At the same time ,the entirely On-Demand property of DSR can significantly reduce the overhead of the routing protocol,save the energy of battery and decrease the probability of packets conflicting and the flooding of potential large-scale route re-fresh.

• 同时DSR协议完全按需(on-demand)的特性可以显著减少路由协议的开销,节省了电池能量,减少了分组冲突的概率并减少了潜在的大规模的路径更新信息的传播。
