摘要
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。
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.
