NS-2随机路点模型在松散网络中节点分布研究

Study on Node Distribution of NS-2 Random Waypoint Model in Loose Network

路由协议是Ad hoc网络关键技术之一,也是影响网络性能的重要因素。研究松散网络中,随机路点模型下不同路由协议的节点分布。通过对几种路由协议的仿真,从分组投递率的仿真结果分析节点在松散网络中的分布。根据仿真结果,当节点运动速率低,节点分布不均匀,分组投递率的结果浮动很大。当节点运动速率提高,节点分布趋向均匀,分组投递率结果较稳定。

Routing protocol is one of the key techniques in Ad hoc network, as well as a significan.t factor on the performance of the networks, the distribution of nodes in different routing protocols with random waypoint model in loose networks is focused on. By simulating several routing protocols, the node distribution of loose networks with the packet delivery ratios is analyzed. According to the simulation results, when nodes moved slowly, they distribu- ted unevenly, and the packet delivery ratio results were volatile. As the nodes＇ speed increased, they tended to distributed uniformly, and the packet delivery ratio results had small fluctuations.
