Abstract: Location service is the primary services in smart automated systems of Internet of Things (IOT). So accurate localization has become a key issue. A novel localization utilizes the neighbor relative received signal strength(NRSS) to build the fingerprint database and adopts a Markov chain prediction model to assist positioning called as novel localization method (LNM) .In the LNM, the history data of the pedestrianís locations are analyzed to further lower the unpredictable signal fluctuations in a smart building environment, meanwhile enabling calibration-free positioning for various devices The performance evaluation conducted in a realistic environment demonstrates superior localization performance compared with existing schemes, when the problems of device heterogeneity and WiFi signals fluctuation exist.

Keywords: Internet of Things (IOT), Novel localization method (LNM), Location Base Services (LBS).
