In this paper, the authors present a two-stage Fingerprint Filtering (FF) approach for the Received Signal Strength (RSS) based location matching in Wi-Fi area. With the popularity of ubiquitous computing and location-based services in a recent decade, the Wi-Fi RSS-based location matching has been one of the most widely recognized methods to locate users' positions due to its low cost of deployment and maintenance. However, the indoor or urban wireless channel is characterized by time varying, non-line-of-sight, and multi-path interference. The efficiency of fingerprints is significantly deteriorated.
