摘要：
One of the major challenges for wireless sensor networks is to long network lifetime while maintaining desired sensing coverage. To solve this problem, we analyse the relation between the desired sensing coverage fraction and the minimum number of working sensors in the randomly deployed sensor networks. Based on the analytical results, an Energy Aware Partial Coverage protocol (EAPC) is proposed, which selects the minimum number of working sensors based on the nodes' residuary energy. Simulation and analysis study demonstrates that the EAPC can effectively reduce the network consumption and achieve the load-balance among all the sensors to meet the desired sensing coverage requirement.
