Abstract Power control techniques for wireless sensor networks are significant for network connectivity, energy efficiency, network capacity, throughput, real time performance and etc. It is one of the supporting technologies for the deployment of wireless sensor networks. This paper proposes an Adaptive Power Control Strategy (APCS) fitted for wireless sensor networks. It is a distributed algorithm based on local information which can obtain an excellent target topology by adjusting the path loss exponent and the power control parameter. It still can satisfy applications of a higher real-time performance and fault tolerance capacity. In addition, the proposed algorithm adopts a dynamic power control strategy to maintain the network connectivity which prolongs the network life time. Simulation results show the effectiveness of the proposed method.
