摘    要:针对无线传感器网络节点负载不均衡的问题,提出了一种应用相对变换的无线传感器网络分簇算法(RTCH)。在成簇阶段,节点将簇头剩余能量、簇头与节点和簇头与基站的传输能耗等参数利用该模型先进行相对变换,再计算簇头适宜度来选择加入簇头成簇,并通过簇头的反馈信息来控制簇的规模来优化网络性能。仿真实验结果表明,RTCH算法能更有效地均衡网络中的能量消耗,延长网络生命周期。

关 键 词:无线传感器网络  相对变换  分簇  负载均衡  能耗

Abstract:To solve the load balance problemin thewireless sensor networks(WSNs),a clustering hierarchy arithmetic based on relative transformation(RTCH) is presented.In the stage to form clusters,the node transforms rest energy of cluster-head,transport energy cost from the node to cluster-head and it between cluster-head to base station used by the model which is presented,and select the optimum cluster-head through calculating.The feedback information from cluster-head control the extent of cluster to improve netwo...
Keywords:wireless sensor networks  relative transformation  clustering routing  load balance  energy cost
