We propose a phased waking three dimensional coverage scheme based on hibernation of redundant nodes for the limited energy of nodes and redundancy in wireless sensor networks. A large number of sensor nodes are randomly deployed in the monitoring region and the redundant nodes can hibernate which will be waken by phases after the on-duty nodes are exhausted. Each node¿s state can be determined at any moment until all of the nodes in the entire sensor network are exhausted. The simulation results show that our method improves the network performance. Besides, the phased waking strategy outperforms the one not by stages, and waking the nodes after hibernation achieves higher network performance than directly waking in turn with the same number of nodes deployed in the 3D monitoring region.
