摘要
LAR是AdHoc网络中一种典型的利用地理位置信息的路由协议。文章首先对LAR做定性分析,然后利用Qualnet,分别对节点移动速度、源节点数、节点平均密度以及数据发送率对LAR的影响做了实验分析。分析表明,LAR路由协议适合于节点以中低速移动,节点平均密度稍高但网络负载不宜过高,报文发送率中高的环境。
LAR is a typical position based routing protocol. This paper make a qualitative analysis on LAR firstly, and then it makes an experiment on how LAR is influenced by the moving speed of the nodes, the number of source nodes, the average density of nodes and the sending rate. the experiment is based on Qualnet, the conclusion is that LAR works best in a condition that the nodes move with a low or medial speed, the node density is high with a small set of nodes sending data, and the sending rate is high.
