WSN中节点发射距离自适应调整算法研究*

On the basis of analyzing the characteristics of date and energy consumption for sensor nodes, this paper proposed two transmission range adjustment algorithms as improved methods of DTA algorithm in order to avoid energy hole in wireless sensor networks. The optimization goal of the two proposed algorithms were the sum of absolute value of energy consumption difference for sensor nodes between neighboring layers and energy consumption variance respectively. The simulation results show that both of the improved algorithms are better than DTA algorithm, for algorithm 1 and algorithm 2 extends the network lifetime about 44% and 56% respectively.
