스마트 폰의 GPS 정보를 이용한 무선랜 접속점 위치 측정 방법

In this article, we propose a new method for precise WLAN (Wireless Area Network) AP (Access Point) localization using GPS information measured in the smart phone. The idea is that the possible area of WLAN AP location, called AP_Area, is first determined by measuring GPS information and the received signal strength in the smart phones. As the number of measurements from the smart phones increases, the AP_Area are successively narrowed down to the actual AP location. We have performed the simulation to evaluate the proposed algorithm. The simulation results show that the proposed algorithm can detect the Wi-Fi AP localization within 5 m (probability over than 90%).
