A Centralized Multi-Floor Indoor Navigation System for a Large Mall

In this paper, a new Indoor Positioning System (IPS) is introduced. The IPS allows people to navigate in an indoor environment such as malls, public buildings, hospitals and airports where GPS cannot be used due to accuracy problem. The proposed system addresses the multiple floor localization, which is not addressed carefully by researches. The system can recognize the user place across multiple floors, using the Wi-Fi Received Signal Strength Indicator (RSSI) and a smartphone barometer sensor to build the indoor environment radio map. The system is to be implemented and tested at Seef mall Arad in the Kingdom of Bahrain. Such new applications will enrich the quality of life and help in converting our building and city to a smart one.
