Abstract

the importance of location based service has been addressed frequently in various fields and the interest about core technique of various positioning scheme for indoor has been increased. The positioning scheme based on Wi-Fi is widely used because the infrastructure is already set up in many indoor spaces. The fingerprinting and the lateration schemes are typical techniques for Wi-Fi based positioning. However, these schemes have some problems for actual execution, such as hard-works for building data base and the time-varying characteristics of wireless signal. In this paper, a novel received signal strength (RSS)-ratio based positioning is proposed to mitigate the problems of conventional schemes. The performance of proposed scheme is evaluated in normal office environment according to various number of selection APs. According to the experiment results, the positioning error of proposed scheme is reduced about 82% than that of conventional RSS lateration scheme.
