Location-based service is a value-added service through mobile communication networks and geospatial information technologies. In existing positioning systems, Global Positioning System (GPS) is the most widely used system; however, it is not applicable in an indoor environment. Therefore indoor localization systems have continually been proposing. How to build an indoor localization system via an infrastructure of wireless sensor networks is the focus of this paper. Additionally, a test bed was built in order to evaluate and analyze the performance of the system.
