Ad Hoc网络中一种基于传输功率的分簇算法

摘要

Nodes in Ad Hoc network move without rule, so the problems of routing protocol and QoS guarantee face new difficulties. Architecture of grade is applied widely in Ad Hoe networks to reduce the route cost, and satisfies the request of network extending. A clustering algorithm based on transmission power is given. Comparing the performance of the algorithm with three other clustering algorithms in terms of renffiliation frequency and dominant set update, it is proved validity in respect of cluster architecture stability through simulation experiments.%Ad Hoc网络中无线节点无规律的移动使网络的路由选择、OoS保障等问题面临新的难题.分层结构在Ad Hoc网络中被广泛应用以减少路由开销,满足网络规模扩充的需要.由此提出一种基于传输功率的分簇算法,通过模拟实验对该分簇算法与其他3种分簇算法进行重入簇和统治集更新方面的性能比较,证明该方法有效提高了簇结构的稳定性.
