A study of indoor positioning algorithm to secure WLAN RSSI reliability

Abstract

This study has obtained the results of practical positioning using IEEE802.11-based WLAN which makes it possible to get access to a mobile network anytime and anywhere as it becomes more common in public buildings, colleges and airports and has been used in diverse sectors thanks to mobility, portability and convenience and analyzed indoor positioning methods. Based on the results of the indoor and outdoor positioning experiments, the characteristics of WLAN signals in indoor environment were analyzed. In addition, this study has examined a plan to secure RSSI reliability and indoor positioning algorithm which enhances accuracy in a candidate group for measurement of positioning spots. Then, this study has attempted to figure out the applicability of WLAN positioning system in indoor environment through an experiment. © 2012 Springer Science+Business Media.
