无线传感器网络LEACH协议的能耗研究

The Research for Energy Consumption of LEACH Protocol in Wireless Sensor Network

通过对无线传感器网络LEACH协议的分析研究,提出了一种最佳能量消耗算法,该算法采用簇的最佳能耗范围、基于能量的簇头选举法以及对簇的组建阶段的优化的方式改善了LEACH协议在簇头的产生、簇的范围等方面的一些缺陷。经仿真证明,该算法较LEACH具有有一定的优异性,能有效均衡节点能耗,延长网络生存期。

This paper presents an optimal energy consumption algorithm based on the analysis of energy consumption of LEACH protocol in WSN. This algorithm uses the optimal energy consumption range of the cluster, the energy-based cluster head election method and the optimization of the cluster formation stage to improve the LEACH protocol in the cluster head generation and cluster scope and other aspects of the defects. Compared with LEACH, this algorithm has some advantages. It can balance the energy consumption of nodes and prolong the network lifetime.
