| 摘 要： | 为了研究移动自组网中多播路由协议在不同移动模型下的性能,选取随机路点移动模型、高斯马尔科夫移动模型和参考点组移动模型,将三种移动模型的移动场景加入到NS2中,对基于部分网络编码的实时多播协议PNCRM进行仿真.结果表明,PNCRM协议在随机路点移动模型和高斯马尔科夫移动模型中的数据包投递率明显高于参考点组移动模型,但是参考点组移动模型的总开销和端到端延时是最优的.这样我们就可以根据不同的性能指标要求选择合适的移动模型.

| Abstract: | In order to study the performance of multicast routing protocol in mobile ad-hoc network under different mobility models, we made simulations to get the performance of Partial Network Coding based Real-time Muhicast （PNCRM） protocol in NS2 under the random waypoint mobility model, Gauss-Markov mobility model and reference point group mobility model. The results show that the packet delivery ratio of PNCRM in random waypoint mobility model and Gauss-Markov mobility model is much better than that in reference point group mobility model, but the total overhead and delay of PNCRM in reference point group mobility model is the best. Thus we can select the appropriate mobility model according to the performance requirements. |
