摘　　要：覆盖质量与能量均衡是制约无线传感器网络规模与生存时间的重要因素。针对大规模无线传感器网络中,如何满足一定覆盖率条件的同时,延长网络生存时间这一问题,在LDAS基础上引入基于容忍覆盖区域的感知模型,提出了一种冗余节点的状态调度方法。该方法加入基于剩余能量的冗余判别因素,并通过预休眠节点选举机制,避免了相邻节点同时休眠或工作的情况发生,提高了覆盖效率。仿真实验证明了该方法的有效性,该方法在覆盖质量和能量均衡方面都有较好的表现。Sensor coverage quality and energy balance are important factors to restrict wireless sensor network scale and survival time.As for a concern question that how to extend network survival time on the large-scale wireless sensor network with enough coverage rate,this paper introduced a tolerance coverage model based on LDAS,proposed a sensor node state scheduling method for redundant sensor nodes.The method appended a redundancy distinguish factor based on remaining energy,improved the coverage efficiency by means of a“sleeping vote”mechanism,which avoided the occurrence of adjacent pre-slee-ping nodes turn to sleep or work at the same time.Simulation results prove the effectiveness of the algorithm,it has a good performance on coverage quality and energy balance.
