摘    要:通过分析无线传感器网络的电路模型和能量消耗情况,结合LEACH算法,提出一种基于最小能耗的无线传感器网络路由算法。网络运行时首先将其划分为若干个子区域,再进行簇首节点的选取,这样取代了传统LEACH算法对整片网络随机选取簇首节点的做法,使得簇首节点分布更加均匀。同时,在选取簇首节点之前对每个节点的剩余能量进行判断,低于阈值的采取休眠处理,这样保证了簇首节点选取的有效性。以上两点措施使区域内节点负载分配更加合理,有效地提升了整个网络的生存时间。

关 键 词:无线传感器网络  能耗  簇首节点  阈值

Abstract:Based on analyzing the circuit model and energy consumption of wireless sensor network,a routing algorithm about minimized power for wireless sensor network is proposed combining with LEACH algorithm.When the network began to run,it was divided into several sub-regions,and the cluster head nodes were selected.This way replaced the traditional LEACH algorithm which could randomly select cluster head nodes in the entire piece of network and made the distribution of cluster head nodes more average.Meanwhile,th...
Keywords:wireless sensor networks  energy consumption  cluster-head node  threshold value
