节点的定位是用于应用无线传感器网络的关键技术。通过分析无范围的质心定位算法（CLA）的模型，本文提出了一种新的定位算法，该算法可以称为高级质心定位算法（ACLA）。当随机放置锚节点时，ACLA可以处理CLA的本地化精度劣势。 ACLA的计算是样本，ACLA的通信开销较少。模拟结果表明，与CLA相比，ACLA的定位精度有明显的改善。
Localization of nodes is a key technology for application of wireless sensor network. By analyzing the model of the range-free Centroid Localization Algorithm (CLA), this paper presents a new localization algorithm, which can be called Advanced Centroid Localization Algorithm (ACLA). ACLA can deal with the localization precision disadvantage of CLA when the anchor-nodes are placed randomly. The calculation of ACLA is sample, ACLA has less communication overhead. The simulation results indicate that the ACLA has an obvious improvement in localization precision than CLA.
