摘　　要：近年来,无线自组网因其完全分布式以及灵活组网等特性受到学术界和产业界的广泛关注。将自组网投入实际应用前,仿真分析其性能是必不可少的一个环节。而路由是自组网关键问题之一,路由协议的性能直接影响整个系统的性能。文中分别从分组递交率、平均时延、平均跳数以及路由开销四个方面比较了目前最具代表性的四个路由协议——AODV、DS-DV、DSR和TORA的性能,分析了拓扑变化和网络负载对各协议性能的影响。In recent years, the Ad Hoc network has attracted much more researchers＇ attention because of its completely distributed character. Before we apply it, we should analyse its performance through simulation. Routing, as an important part of Ad Hoc network, its performance has a vital effect on the system. In this paper, we compare the performance of four Ad Hoc network＇ s routing protocols--AODV, DSDV, DSR, TORA, and analyze the effect on the performance of each protocol when changing the nodes＇ speeds and the sending rate.
