—In this paper, we proposed a RSSI-Probability transformation algorithm for radio map construction that improves positioning accuracy and AP (Access Point) weight clustering that reduces the computational burden. To verify the performance, we developed a positioning system called LocNeedle. The experimental results show that our algorithm achieves good localization accuracy and reduces computational burden of online phase.
—Wi-Fi fingerprint localization, RSSI probability distribution, AP weight clustering.
