摘要： 结合无线传感器网络中的最小跳数路由协议，根据功能的不同将传感器节点分为只进行数据采集的终端节点和既进行数据采集又要转发数据的中间节点两类；提出一种节点休眠算法，对前述两种节点采取不同的休眠/唤醒策略以降低能耗。理论分析和仿真结果表明：所提节点休眠算法节约了节点能量，延长了无线传感器网络的寿命。

Abstract: Network nodes are divided into terminal nodes and intermediate nodes according to the different functions which are based on the minimum hop routing protocol in wireless sensor networks. Terminal nodes only collect data, while intermediate nodes not only collect data but also forward them. A node sleeping algorithm that has different sleep/wake-up strategy for the two kinds of nodes is proposed to reduce energy consumption. Theoretical analysis and simulation results show that our proposed node sleeping algorithm can reduce the energy consumption of node and extend the life of wireless sensor networks.
