Abstract: Existing positioning systems do not provide the required positioning accuracy for navigation systems in indoor environments. Novel system approaches are based on fingerprinting and triangulation techniques. Thus, they suffer on low positioning accuracy due to multipath propagation and different sending power of the considered access points. Other approaches are based on tagged WLAN (Wireless Local Area Network) access points or GSM (Global System for Mobile Communication) base stations with their corresponding position stored in a central tag directory. This would cause high communication costs for a mobile device that queries the directory frequently. In this paper we present a filtering technique for access points to determine the closest ones to the mobile device. The geographical position of the mobile device is calculated from the geo tags broadcasted by the access points in the mobile device’s vicinity. Systems based on this approach will provide the same accuracy as directory-b ased positioning systems at a low cost. (More)
