摘　　要：在目前节点调度方案中,节点的休眠时间在整个节点调度过程中都采用固定的休眠设置,这样会导致网络中部分节点的能量消耗过快,引起节点过早失效,无法实现应用监测。针对该问题,提出了动态调整休眠时间的方法,根据节点以及网络剩余能量延长或者缩短节点休眠时间,在此基础上设计出节点休眠时间动态调整的能量节约算法(STDA)。仿真结果表明,该算法不仅能缓解节点过早死亡的问题,并且有效地延长了网络的生存时间。In current node scheduling schemes, the sleep time of the node is fixed during the entire node scheduling process, this leads some of the nodes consume the energy very quickly and fail soon, and makes it unable to achieve the monitoring. To solve the problem, this paper proposed the method of dynamically adjust the sleep time of the node, extend or shorten the sleep time according to the surplus energy of the node, on the basis of this designed the sleep time dynamically adjustment the energy saving algorithm（STDA）. The simulation results show that the algorithm can not only relieve the problem of the death of nodes, but also extend the lifetime of the network effectively.
