介绍了移动自组织网络中典型的路由协议——按需路由协议AODV以及AODV的改进协议AODV_BD。此外还介绍了一个实用的移动模型,使仿真实验更加接近实际应用。在Linux下使用网络仿真工具NS2对这两个协议进行仿真,并用分组交付率和端到端延时对仿真结果进行分析比较和性能评价。由此得出,AODV_BD协议与AODV协议相比,在一定程度上减少了分组时延。
介紹瞭移動自組織網絡中典型的路由協議——按需路由協議AODV以及AODV的改進協議AODV_BD。此外還介紹瞭一箇實用的移動模型,使倣真實驗更加接近實際應用。在Linux下使用網絡倣真工具NS2對這兩箇協議進行倣真,併用分組交付率和耑到耑延時對倣真結果進行分析比較和性能評價。由此得齣,AODV_BD協議與AODV協議相比,在一定程度上減少瞭分組時延。

The paper presents the typical muting protocols: the Ad hoe on-demand muting protocol(AODV) in mobile Ad hoe networks and the improved protocol AODV_BD for protocol AODV; also presents a practical mobility model that enables the simulation experiment more veritable. Then it uses network simulation tool (NS2) to simulate the two routing protocols in Ad hoe networks based on Linux and then compares and analyses the simulation results and do performance evolution with packet delivery ratio and end-to-end relay. We can infer that AODV_BD muting protocol reduces the packet delay to a certain extent compared with AODV routing protocol.
