摘要： 降低能耗可延长网络生存时间，在传感器节点高密度部署的环境中，在保证网络性能的前提下，将最少量的节点投入活跃工作状态，而将其余节点投入低功耗的睡眠状态。在满足上述覆盖性和连通性要求的基础上，讨论如何选择最少数量的工作节点，以及如何计算同时满足覆盖要求和连通性要求的问题。

Abstract: Reducing the energy consuming can prolong the survival of the networks. In the high density deployment of sensor nodes, under the precondition of the network capability, this paper takes the least nodes into the active state, and makes the other nodes into the low energy consumption of the sleep state. Under the precondition of coverage and connectedness mentioned above, it provides a way in how to select the least working nodes and to compute both meet to the coverage request and connectivity request.

Key words: Wireless Sensor Networks(WSN), coverage, connectivity
