摘要
质心定位算法是WSN中一种典型的定位算法。首先对质心定位算法和自由空间传播模型进行分析，然后在网格中随机部署未知节点和锚节点，通过改变锚节点个数、节点通信半径等参数，研究其对节点定位误差的影响。实验结果表明，总节点数量一定时，锚节点数量和通信半径对定位精度存在较优值。
Abstract
Centroid localization algorithm is a typical algorithm in wireless sensor networks. Analyzes centroid localization algorithm and free space propagation model. Then distributes the unknown nodes and anchor nodes randomly in the grid, by changing the number of anchor nodes and communication range, analyzes the effects of the parameters like the number of anchor nodes and communication range on the posi-tioning error. The test results indicate that when the total number of nodes is fixed, anchor nodes and communication range would opti-mize the positioning accuracy.
