在深入分析战术互联网特点的基础上,选取适合战术互联网节点移动特点的参考点群组移动模型,选择了几种具有代表性的无线路由协议,基于ns2网络模拟平台,以参考点群组移动模型生成移动场景文件,应用层使用CBR数据流量,对这几种协议在不同参数条件下的性能进行了模拟测试。通过对测试结果数据的分析,总结出了几种路由协议在战术互联网条件下端到端延迟、报文交付率和路由负载三个方面的特点。为进一步在战术互联网下作相关研究提供参考。
In this paper,several representative wireless routing protocols were simulated based on ns2 network simulation platform with different parameters.The simulation scene was generated based on reference point group mobility model and data flow is CBR flow.The reference point group mobility model was selected as the tactical Internet mobility model after a deep analysis of tactical Internet features.The features of routing protocols in terms of end-to-end delay,packet delivery ratio and routing overhead were concluded under tactical Internet environment.Our work is useful for further study about tactical Internet.
