摘要
运用NS2网络仿真模拟软件对Ad hoc移动自组网络三种典型路由协议DSDV、DSR、AODV在不同网络拓扑复杂度环境下进行仿真模拟,提取部分仿真数据进行分析,从数据包发送率、端到端延时、路由开销三个方面综合比较Ad hoc网络三种典型路由协议的优缺点;引入NS2节点能量模型,分析仿真过程中节点能量变化。仿真结果表明,随着网络拓扑复杂性的增加,AODV路由协议较其它两种路由协议更具可行性与有效性。
Analyzes and compares three tipical routing protocols： DSDV,DSR and AODV for Ad hoc network,and then simulates the results with NS2 in different net topology complexity,and shows the performances of them in recv/send rate of node,end-toend delay and routing overhead by analyzing part of simulation data.Finally,analyzes the change about energy of nodes in simulation by energy model in NS2.The simulation results that the on-demand protocol AODV provides better feasibility and effectivity when the net topology becomes complex.
