The recent decade has witnessed a rapid growth in wireless communications technology. This study presents a location management scheme for integrated wireless networks and a signal-based positioning algorithm for WLAN. The proposed location management scheme provides location information to obtain from a hierarchical location database to mobile users and LBS providers. Additionally, a signal-based positioning algorithm is developed for indoor positioning based on WLAN received signal strength indication (RSSI). Approximated distribution modeling is applied to calculate the probability of users appearing in training points. This mechanism not only locates a mobile client precisely, but also reduces the cost of locating. A performance evaluation is performed to indicate the effectiveness of the proposed location management method, and provide suitable parameter settings.
