Abstract

Indoor Localization that is based on received signal strength indication (RSSI) needs Log Path Loss Model for ranging. Parameters on the model should be optimal according to the environment. This paper will investigate Dual Log Path Loss Model that has practical parameters. The novel Indoor Localization algorithm based on WLAN and the method to determine the location of AP are proposed too. Two methods show lower distance error in general indoor environment.
