    An indoor Wi-Fi access points localization algorithm based on improved path loss model parameter calculation method and recursive partition by Wenyan Liu, Xiangyang Luo, Qing Mu, Yimin Liu, Fenlin Liu

    Published 2019-05-01
    “…The algorithm recursively partitions the region where the target Wi-Fi access points are located according to the idea of quadtree partition, and partitions it into same sub-grids, which is sequentially performed until the sub-grids are smaller than the set threshold. The detection device is used at the detection location of the grids to measure the received signal strength, which is from the detection points to the target access point, the grid center point is used as the location of the candidate target access point, the parameters in the path loss model are calculated by using the signal strength differences between the detection points, and then the distances between the detection points and the target access point are calculated by using the signal strength values from the detection points to the target access point. …”
