中文摘要：
提出一种冗余节点休眠调度算法来延长网络生命周期.调度过程中重点考虑两方面问题：一是采取策略防止大量节点同时从工作状态转入休眠状态以防止大量盲区同时产生;二是根据邻居表中节点的工作邻居数量,判定节点是否处于网络边界,对边界节点和内部节点采用不同的调度策略,防止边界收缩.仿真结果表明,算法能有效延长无线传感器网络的生命周期.
英文摘要：
A scheduling algorithm for redundant nodes is proposed to effectively prolong the lifetime of WSN. The algo-rithm focuses on two problems. One is to prevent a large number of nodes shifting at the same time from working stateinto sleeping state to avoid the appearance of blind areas, the other is to employ different scheduling strategies on bordernodes and internal nodes to avoid contraction of the network boundary by judging whether a node is on the networkboundary according to the number of working nodes in its neighbor table. The simulation results show that the algorithmcan effectively prolong the lifetime of WSN.
