摘　　要：AdHoc网络是一种由移动节点组成、拓扑结构动态变化的自组织网络。网络中没有固定的网络基础设施。由于移动主机的通信范围有限 ,相距较远的主机需要通过其他主机的“多跳”转发才能通信 ,因此网络中的主机同时也作为路由器为其他主机转发报文。目前设计的各种AdHoc路由协议大多数并没有具体的性能分析与比较。本文介绍几种典型的路由协议 :DSDV ,TORA ,DSR和AODV ,利用Ns 2进行仿真 。Ad Hoc network consists of a collection of wireless nodes, all of which may be mobile; dynamically create a self organizing network without using any network infrastructure or administrative support. Due to the limited transmission range of the mobile nodes, multiple network hops may be needed for the node to forward packets for other nodes in the network that may not be within direct wireless transmission range of each other. Therefore,each mobile node in the network operates not only as a host but also as a router. A number of routing protocols have been proposed for Ad Hoc network. This paper will introduce four typical protocols: DSDV, TORA, DSR and AODV briefly, model an Ad Hoc network in detail and present the result of the simulation.
