摘要： 移动Ad Hoc网络(MANET)是由一组无线移动主机组成的一个没有任何事先建立好的基础设施或集中管理设备的临时网络，其特点是网络拓扑易变，带宽、能源有限及容易受到攻击等。该文对AODV, DSR, DSDV这几种典型的路由协议进行分析比较，指出它们的优缺点及适用场合。通过2个场景的配置，从路由开销、分组投递率、端到端的平均时延3个方面进行实验。仿真结果表明，按需路由协议在3个方面都表现出较好的性能。

Abstract: Mobile Ad Hoc Networks(MANET) are collections of wireless mobile nodes, constructed dynamically without the use of any existing network infrastructure or centralized administration. MANET are characterized by limited power resource, high mobility and limited bandwidth, so on. This paper compares the performance of two prominent on-demand reactive routing protocols for MANET: DSR and AODV, along with the traditional proactive DSDV protocol. An experiment is carried out by using two scene configuration and three facets: routing load, packet delivery fraction, average end-to-end delay of data packets, and the result proves that on-demand routing performance better on packet delivery fraction, average end-to-end delay of data packets, normalized routing load.
