摘要
通过对无线传感器网络节点通信子系统能耗的分析,采用动态竞争算法,在区域内竞争出集群主从两类节点,提出一种节省能耗的新策略。该策略可以有效减少系统对能耗和通信带宽的要求,从而延长无线传感器网络中节点的生命周期。
A new strategy with Dynamic Competition Algorithm - DSA for energy - saving was proposed based on the analysis of energy consumption during the period of communication in sensor nodes, which decide two types of sensor nodes ： the cluster master and the slave. This approach reduces both power consumption and communication bandwidth requirements. It prolongs the lifetime of sensor nodes in WSNs.
