Distributed Location Estimation System Using WLAN Received Signal Strength Fingerprints

Free registration required

Executive Summary

Location Estimation has become important for many applications of indoor wireless networks. Received Signal Strength (RSS) fingerprinting methods have been widely used for location estimation. The accuracy and response time of estimation are critical issue in location estimation system. Most of the location estimation system suffers with the problem of scalability and unavailability of all the access points at all the location for large site. In this paper, the authors have proposed a distributed location estimation method, which divide the location estimation system into subsystems. Their method partition the input signal space and output location space into clusters on the basis of visibility of access points at various locations of the site area.
