摘要： 提出一种基于遗传算法的无线传感器网络节点自定位技术，在算法的第1阶段利用采样方法对节点初始位置进行初步估计，在 第2阶段采用遗传算法对节点初始位置进行求精。仿真实验结果表明，该算法在锚节点比例较低的情况下仍然能够对未知节点进行准确定位，且定位精度更高。

Abstract: A novel localization algorithm based on Genetic Algorithm(GA) is presented. The algorithm is divided into two stages. The sampling method is used to obtain initial location and the initial location is refined based on GA. Simulation experimental results show this algorithm is effective for Wireless Sensor Network(WSN). Its location accuracy is better.
