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 ,并对仿真结果进行分析
AdHoc network is a self-organizing network composed of mobile nodes and dynamically changing topological structure. There is no fixed network infrastructure in the network. Because the communication range of mobile hosts is limited, hosts that are far away need to communicate through “multi-hop” forwarding of other hosts. Therefore, hosts on the network also serve as routers for forwarding messages to other hosts. Most current Ad Hoc routing protocols designed and no specific performance analysis and comparison. This article describes several typical routing protocols: DSDV, TORA, DSR and AODV, using Ns 2 for simulation, and the simulation results were analyzed
