“…Though Global Positioning System (GPS) can provide accurate and reliable position information for location services, it cannot be used effectively under indoor environment [1]. To overcome this limitation, researchers have proposed many creative localization technologies such as sensor network, RFID, and Wi-Fi [2, 3]. Among them, Wi-Fi positioning technology has attracted extensive attention because it is built upon mobile phones, which are used widely all over the world [4].…”

With the development of the wireless communication technology and intelligent mobile phone, the positioning services based on Wi-Fi and mobile phone are increasingly demanded. In this paper, a Wi-Fi fingerprint localization method is proposed on the basis of important access points (IAP). For the Wi-Fi fingerprint, Wi-Fi access point with the highest received signal strength (RSS) is denoted as the important access point. At the localization stage, the fingerprints are chosen with the same IAP as the estimated fingerprint from the database. Then, the distance and the AP repetition of the fingerprints are used to calculate the similarity degree. The location of the fingerprint which matches the estimated fingerprint well can be regarded as the estimated location. Experimental results show that the proposed algorithm can achieve high accuracy in indoor environment.
