中文摘要：

针对无线传感器网络节点能量有限的问题，设计一种中继节点自适应休眠方法，对网络节点的工作时间进行优化调度。在路由链路建立中，根据网络中节点的地理位置、剩余能量选择中继节点的方法进行节点休眠调度。网络工作时通过计算下一跳最佳节点位置，选取其附近区域内剩余能量多的节点作为下一跳的转发节点，设计出中继节点自适应选择的节点休眠机制。仿真结果表明，所设计的休眠机制提高了节点能量利用效率、延长了网络工作时间。

英文摘要：

According to the characteristic that the node energy in the wireless sensor networks is limited, a self-adapting sleeping method of relay node is designed to optimize and dispatch the operational time of network nodes. In the routing link es- tablishment, the method is to select relay node according to the geographical location and dump energy of the nodes in wireless sensor network to conduct the node sleeping scheduling. As the network is working, the next optimal node location is calculated and the nearby node with more dump energy is chosen as the next transmitted node. The simulation result indicates that the pro- posed sleeping mechanism has improved the energy efficiency of the nodes and extended working time of the network.
