基于NS2的Ad-Hoc网络典型路由协议的研究与仿真

无线自组织网络是一种完全由无线节点或终端自主构成的通信网络,常用于需要紧急或临时搭建网络环境下应用,具有独立于固定基础设施、带宽有限和拓扑结构易变等特点.本文以Ad-HOC网络为研究内容,重点介绍了Ad-HOC网络的组网关键技术——路由协议,以网络仿真器NS2作为仿真平台,对比在不同移动节点数目和节点不同停留时间两种情况下,DSDV、DSR和AODV这三种路由协议的性能差别,对Ad-HOC的组网具有指导意义.

Research and simulation of typical routing protocol of Ad-Hoc network based on NS2

Ad-Hoc network is a communication network constituted by wireless nodes or terminals independently. With the characteristics of fixed-infrastructure-independent structures, limited bandwidth and mutable topological structure, Ad.Hoc network is often used for practical application in emergency or temporary situation. In this paper, Ad-Hoc network is researched and the key r technology of networking --routing protocol is introduced. With network simuiator NS2 as the simulation platform, the performance difference of DSDV, DSR and AODV are compared in the condition of different mobile node number and pause time. The research has guiding significance for Ad-Hoc networking;
