Abstract— Sensing, processing and communication can consume energy in wireless sensor network. The lifetime of wireless sensor network can be extended by efficient power management. One efficient method to extend the network lifetime is to divide the set of all deployed sensors into non disjoint subsets or sensor covers so that each sensor cover can monitor the entire targets. Adjusting the sen...
