为了研究Ad Hoc网络中的按需路由协议的性能，基于NS2仿真平台，研究分析了移动速度对两种典型按需路由协议AODV和DSR的性能影响，并对DSR协议进行了改进。性能参数包括分组投递率、端到端的平均时延、路由发起率、归一化路由开销等性能。仿真结果表明，DSR协议在移动环境下的性能较好，并且改进后的DSR协议在分组投递率、端到端时延方面均优于原DSR协议。

In order to study the effect of the speed on the performance of the on-demand routing protocols in Ad Hoc network, two typical routing protocols AODV and DSR are simulated in NS-2 simulation platform and an improved DSR is proposed. The performance parameters include packet delivery ratio, average end-to-end de-lay, routing rate, and normalized routing overhead. Simulation results demonstrate that DSR has a better perfor-mance and that the improved DSR is superior to the original on packet delivery ratio and average end-to-end delay.
