  Abstract

In this paper, we propose a method to improve a positioning accuracy considering an indoor wireless channel environment in estimating the location of a mobile device using a signal strength of Wi-Fi communication. Since the indoor channel environment is very complicated and several path loss models are overlapped, it is difficult to apply the conventional localization algorithm. In particular, since the channel varies depending on the number of walls existing in the path, the path loss models among the APs connected to the device at a specific moment could be different from each other. In this paper, we propose a channel modeling about multi - channel environment and positioning method selecting path loss models for links to minimize positioning error. Based on the data measured in the actual indoor space, we made channel model and the performance of the proposed algorithm is verified through simulation and evaluation using real data.
