Abstract: Objective Considering the problem of estimating the location of wireless access points,an algorithm,using RSS-based ranging techniques,which does not need ranging model parameters,is proposed.Itfirstly eliminates the ranging model parameter related to the transmit power for the wireless accesspoint through the ratio relationships between the distances;and then it searches the best path loss in-dex based on the principle of least squares to determine the location of a wireless access point.Simula-tion results show that the algorithm can overcome the shortcomings of the existing location estimationalgorithms for wireless access points,and has better estimation accuracy.
