摘　　要：文章介绍了常用的基于距离的无线传感器网络自定位机制,在建立定位算法求解数学模型和定位性能描述的基础上,提出了一种新的基于智能估算的节点自定位算法.该算法对所得解进行一次甚至多次的选择优化,以提高定位精度.仿真结果表明,新算法与较常用的极大似然估计定位算法相比能够显著提高节点定位精度.As an important support technology, the localization in wireless sensor networks （WSNs） is well worth studying. In this paper, mechanisms of some commonly used self-localization networks were introduced, and a new localization algorithm was proposed based on the analysis of a mathematical model and position performance. The new algorithm worked to enhance the localization accuracy by optimizing localization results circularly. The simulation showed that the new algorithm has a more satisfying localization precision compared with other localization algorithms.
