Research on Power Control in Wireless Sensor Networks

Power control is one of the most fundamental problems in research of wireless sensor networks. It is of great importance to prolonging the lifetime of networks,reducing the interference of communications,improving the efficiency of MAC and routing protocols,among other things. In this paper,we make a general introduction to the advances of power control,and propose a new proximity-graph-based algorithm. Our theoretical analysis and simulation results show that it has a good performance.
