Since the conflict among coverage, number of work hot spots and energy balancing of wireless network, this paper mainly discuss network communications optimization and the network lifetime extending. In order to select the optimal coverage hot spot set, considering the balanced energy consumption characteristics of the network area, this paper proposes a covering algorithm of hot spot scheduling based on the sleep energy balance. The paper builds the network of probability sensing model, calculates the actual energy consumption of the hot spots, and add these two results to the control algorithm to optimize coverage and the number of work hot spots and network equalizer coefficients of energy consumption. Furthermore, the paper realizes hot spot sleep and work scheduling using energy-related scheduling algorithm. Experimental results show that the coverage control strategy can achieve higher coverage, reduce energy consumption and ensure the network energy balance, thus extend the network lifetime.
