摘　　要：针对无线传感器网络中map-growing算法的定位能耗高和定位精度低的特点，提出一种新的改进算法。并从不同的信标节点比例、节点通信半径等方面比较map—growing，APIT算法和改进算法的性能。仿真实验结果表明，改进算法后的map-growing＋比改进前的算法在定位精度上有明显提高。Wireless sensor networks map-growing localization algorithm for high energy consumption and the characteristics of the low positioning accuracy,a new improved algorithm.And from a different ratio of beacon node,the node communication radius and so more map-growing,APIT algorithm and the improved performance of the algorithm.Simulation results show that the improved algorithm after the map-growing ＋ in front of more than improving the accuracy in positioning algorithm has improved markedly.
