Abstract
This paper describes a method for localization of a mobile wireless LAN client such as a smart mobile phone, based on simplified measurement in a multistory building. The method uses the strength of received signal from wireless LAN access points. The method needs lots of data of the received signal strength at various positions in the building. The paper focuses on an estimation system for localization based on a simplified measurement of the signal strength and the measurement position in the building. We examine changes of the conditions of the signal strength based on the interval for request of the received signal strength to the wireless LAN client. Then, a simplified measurement of the signal strength using a motion sensor is proposed. Experimental results show the feasibility of the proposed method.
