摘要
为了进一步完善ZigBee定位技术,减少多径效应对室内定位的影响,在接收信号强度指示算法(RSSI)的基础上,提出了一种自适应动态区域误差因子算法,通过将最小二乘法与自适应动态区域误差因子相结合的方法,来计算盲节点的位置坐标,以达到提高定位精度的效果。Matlab中的仿真结果证明,在节点处于静态和动态两种情况下,该算法在定位精度上都有显著的提升。
In order to further improve the ZigBee positioning technology and reduce the muhipath effects on indoor positioning, an adaptive dynamic regional error factor algorithm is proposed on the basis of received signal strength indicator. This algorithm, by combining the least square method with adaptive dynamic area error factor, calculates the coordinates of the blind nodes and thus improves the positioning accuracy. The simulation with Matlab indicates that both the complexity and the positioning accuracy of the algorithm could be significantly improved.
