The popularity of WLAN and mobile devices makes the development and widely use of location-aware systems and services possible. Since the Received Signal Strength Indication (RSSI) can be obtained by most mobile devices, the fingerprinting method based on RSSI becomes a simple and efficient method of Indoor Location (IL). This method needs to use the empirical measurements, propagation modeling or...
This paper develops a simple and efficient position method based on relative signal-strength prediction, which can be got from an inversion propagation model in cellular networks. The inversion propagation model can predict the propagation loss between any two points along the virtual propagation path from the base-station to mobile-station, which precision has been presented in. So the user's location...
