Wireless sensor networks is a multi-hop self-organizing networks system that consist with vast majority of low-cost node arrayed in the monitor area and formed by wireless technology. This paper is oriented to the demand of preferential energy efficiency and brings forward related control algorithm solution to the heated questions about decreasing network energy-consumption and realizing energy-balance. Based on general probability perceptive model, two coverage control algorithms are put forward respectively. The main idea of algorithm is to make use of a few of higher energy left nodes to buildup network coverage sets and connectivity coverage sets. Reset the cycle of next coverage sets until last sets expire. Use different nodes to form the coverage sets as much as possible to in every new cycle to decrease and balance the energy-consumption.
