无线自组网路由协议仿真

The routing Protocol simulation in wireless Ad hoc network

根据特定海上作战通信指挥想定模型进行通信网络性能仿真,以期在特定战场环境下设计和优化网络配置。首先建立了海上通信指挥想定模型,包括节点模型和指挥业务模型,根据所建模型,利用GloMoSim工具对无线自组网四种典型的路由协议进行了仿真分析。仿真结果表明在特定作战想定背景下,网络带宽对网络性能(分组成功递交率、平均吞吐量、平均端到端时延)影响明显,而节点运动速度对网络性能影响并不明显,这与小覆盖范围下的商用网络有很大不同。

This paper carries out the performance simulation of communication network based on the maritime operation communication command scenario model, in order to design and optimize the configuration of network in special battlefield environment. We first establish the maritime communication command scenario model, which includes node model and command service model. According to these models, the paper conducts simulation analysis on four typical routing protocols of Wireless Ad hoc Network by the tool of GloMoSim. The simulation results show that, under specific background, network bandwidth has a significant influence on the perfonnance of network （such as packet delivery ratio, average throughput, average end-to-end delay）, and the influence of the node＇s velocity is not obvious on the performance of network, which are greatly different from the little-scale commercial network.
