WPCS Coverage Strategy for Wireless Sensor Network
无线传感器网络的WPCS覆盖策略

An effective approach for extending wireless sensor network lifetime is scheduling sleep intervals for extraneous nodes. But most of the existing coverage protocols are based on the circular sensing module. So, how to combine consideration of coverage and connectivity maintenance in a single activity scheduling is discussed in this paper, when the sensing module is not circular. The Well-Proportioned Coverage Strategy (WPCS) is presented which extends the lifetime of sensor network by minimizing the overlap area. Simulations show that WPCS outperforms Coverage Configuration Protocol (CCP) and is suitable for various situations. It effectively reduces the number of activity nodes and extends the lifetime of sensor network.
