基于LEACH的无线传感器网络节能算法

Energy saving algorithm on wireless sensor network based on LEACH

为了最大限度地延长无线传感器网络的生命周期,结合已有的研究,提出了一种基于LEACH的节能算法。所有节点分为固定的聚类,聚类内节点自动轮换担任聚类首领;同时尽可能少地进行控制信号传输,以减少网络通信流量。仿真实验结果证明,该算法在延长网络生命周期方面要优于基于LEACH的固定聚类算法。

To prolong wireless sensor network＇s lifecycle as far as possible, an energy-saving algorithm on the basis of the obtained results was proposed. All sensors were divided by base station into several static clusters, in which each sensor became cluster-head by turn. Thus, transport control signals were as little as possible reduced in the network communication. The simulation results show that this algorithm excells the traditional energy-saving algorithm based on Low-Energy Adaptive Clustering Hierarchy （LEACH） in prolonging network＇s lifecycle.
