摘　　要：移动Ad hoc网络是移动节点动态临时组建的自组织网络,路由协议一直是Ad hoc网络研究的关键问题。本文使用网络模拟器NS-2,设定特定的仿真环境,在不同节点密度、节点移动性、网络负载条件下,对Ad hoc网络路由协议DSR、DSDV、AODV、TORA的分组投递率、路由负荷、端到端延时等性能进行了详细比较与分析,给出了性能曲线并阐明各协议的特性与适用环境。Mobile Ad hoe network is a self - organized network formed dynamically and temporarily by mobile nodes. Routing protocol is a key problem and critical to mobile Ad hoe network. Based on NS- 2, the simulation runs under different node density, node mobility and network load. The performances of DSR, DSDV, AODV, TORA are compared according to packet delivery ratio, end - to- end average delay, and normalized routing load. And performance curves are given in this paper, which show the corresponding network each protocol fits.
