Reducing the site survey using fingerprint refinement for cost-efficient indoor location

Recently, RSS fingerprint-based location has been considered as a low-complexity solution for indoor localization. However, constructing a fingerprint map requires a great amount of manual effort to achieve a high location accuracy. In this paper, we present a refinement method to reduce the necessary manual effort without degrading the location accuracy. This method transforms a coarse-gained fingerprint map containing only a small number of...
