Abstract EN
The rapid growth of mobile communication and the proliferation of smartphones have drawn significant attention to location-based services (LBSs).
One of the most important factors in the vitalization of LBSs is the accurate position estimation of a mobile device.
The Wi-Fi positioning system (WPS) is a new positioning method that measures received signal strength indication (RSSI) data from all Wi-Fi access points (APs) and stores them in a large database as a form of radio fingerprint map.
Because of the millions of APs in urban areas, radio fingerprints are seriously contaminated and confused.
Moreover, the algorithmic advances for positioning face computational limitation.
Therefore, we present a novel irregular grid structure and data analytics for efficient fingerprint map management.
The usefulness of the proposed methodology is presented using the actual radio fingerprint measurements taken throughout Seoul, Korea.
