摘要：In this paper, we consider problem of positioning of mobile phones, different approaches were produced for these targets using GPS, WiFi, GSM, UMTS and other sensors, which exist in today smart phone sensors. Location awareness in gen-eral is emerging a tremendous interest in different fields and scopes. Position is the key element of context awareness. How-ever GPS produces an accurate position, it requires open sky and does not work indoors. We produce an innovative robust tech-nique for positioning which could be applied on terminal-based or network-based architecture. It depends only on Received Sig-nal Strength (RSS) and location of Base Transceiver Station (BTS). This work has been completely tested and analyzed in Egypt1 roads using realistic data and commercial android smart phone. In general, all performance evaluation results were good. Mean positioning error was about 120 m in urban and 394 m in rural.
