A low-complexity floor determination method based on WiFi for multi-floor buildings

초록

Floor determination has become an extremely urgent issue to resolve because many applications require accurate information on floor numbers to provide better localization services. This paper presents a Wi-Fi based, lowcomplexity floor determination method for multi-floor buildings. In this paper, the Multi-Wall-Floor (MWF) model is used in the simulation and the analysis. Simulation results show that the floor determination accuracy is nearly 100% if the deployment density of Wireless Access Points (WAPs) is sufficiently high on each floor. It is also shown that the proposed method provides a good estimation of floor determination even when only a few WAPs are implemented on each floor. In our scheme, detailed information on the WAP coordinates is not needed, except floor ID and Received Signal Strength (RSS) of each WAP. The novelty of the proposed method is that it can work in extreme conditions, where there are no WAPs on the floor. Copyright © 2013 IARIA.
