基于DSR的位置预测分簇算法

提出一种将动态源路由(DSR)协议与基于位置预测的分簇算法相结合的Ad hoc网络路由算法.算法中利用位置预测算法进行分簇,簇内成员无需路由功能,同时根据实际需要和应用环境做出合理的位置判断,针对动态变化的无线网络环境,进行归一化处理.算法中位置信息通过GPS或者自定位算法获取,簇头运行DSR协议充当路由转发器,使不同簇节点之间的通信依赖于各簇的簇头,大大减少了网络路由信息的冗余.模拟结果显示该算法性能具有良好的分组递交率和较低的平均端到端分组时延.

The Research on Clustering Algorithm of Position Forecast Based on DSR

A new Ad hoc routing algorithm combining the dynamic source routing(DSR) protocol with the position prediction-based clustering algorithm is presented in this paper.In the algorithm the prediction-based algorithm is used to detach the different clusters,and to pass a reasonable position judgment based on actual needs and implement environmental,the same treatment is done aimed at the dynamically wireless network environment,by the way,the members in clusters do not need the routing function.Location informa...
