Wireless Tracking Analysis in Location Fingerprinting

Free registration required

Executive Summary

Wireless tracking analysis is useful for deploying the efficient indoor positioning system. Location Fingerprinting (LF) method uses a training dataset of Wi-Fi Received Signal Strength (RSS) at different location to track the target. Fuzzy logic modeling can be applied to evaluate the behavior of wireless Received Signal Strength (RSS). Previous analytical models based on LF are not sufficient for modeling spatial factors of wireless coverage. Spatial analytical model is useful for analysis of how the wireless infrastructure affecting the accuracy of positioning. The main concept of fuzzy logic is to reflect the reality of the people world of experience, which is uncertain and fuzzy. In this paper, the authors develop a multi-layer fuzzy modeling for the wireless coverage in the huge and open area.
