| 摘 要： | 根据井下人员定位系统对定位方法的要求，提出了基于RSSI(Received Signal Strength Indicator)的加权质心定位算法，它综合了基于测距的定位和非测距的定位，并将固定锚节点之间的距离和信号强度信息考虑进来对固定锚节点的权值进行校正.实验结果证明，所提出的算法能够提高定位精度.

| Abstract: | For the requirement of underground localization,RSSI(Received Signal Strength Indicator) based centroid-weighted localization algorithm was proposed.The algorithm combined range-based and range-free localization methods and considered the information of distance and signal strength between fixed anchors to correct the weight coefficients.Simulation results demonstrate that the algorithm can improve the localization accuracy. |
