Particle Filter Based WiFi Positioning System Implementation Using WiFiSLAM Radio Map

Abstract

In this paper, we present the particle filter based WiFi positioning system (WPS) implementation using WiFiSLAM radio map. To make the radio map for WPS, we apply two methods. In case that map data is given, dynamic search (DS) is applied to construct the radio map. If the map data does not exist, the WiFiSLAM is used to make the radio map. To demonstrate the performance of WiFiSLAM radio map, we estimate the position of user using WiFiSLAM radio map. The experimental results show the positioning error from WiFiSLAM radio map is similar with the positioning error from the DS radio map.
