Three-Dimensional Positioning Algorithm via Particle Swarm Optimization Based on Wireless Sensor Network

设计了一套基于粒子群算法的ZigBee无线传感网络3D定位算法。采用ZigBee节点JN5148进行测距,并对测距效果和误差进行分析。在设计粒子群算法目标函数时,根据测距距离远近赋予数据不同权重。仿真实验证明,本文定位算法性能良好。

In this paper, a three-dimensional positioning algorithm based on ZigBee is designed. We analyze the error of ranging data measured by JN5148. To improve positioning accuracy, we assign different weights to the ranging data when we obtain the optimal solu-tion of the target function. Finally, the simulation results show that this algorithm has good performance.
