摘要
在研究移动自组网移动模型和无线路由协议的基础上,选取移动自组网中具有代表性的参考点群移动模型,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OLSR无线路由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详细分析,总结得出了OLSR无线路由协议在参考点群移动模型下端到端时延、报文交付率和路由负载三个方面的特点。为进一步研究移动自组网下基于OLSR协议的各种应用提供参考。
Based on study of the mobility model of MANET and wireless routing protocols , OLSR wireless routing protocol was 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 is selected as mobile ad hoc network mobility model . The features of the OLSR routing protocol in terms of end-to-end delay, packet delivery ratio and routing overhead are concluded under reference point group mobility model. The work is useful for further study about variety applications based on OLSR wireless routing protocol in mobile ad hoc network.
