Indoor Positioning and Monitoring System: Using Smartphone Sensors, Virtual Map and WLAN

The inspiration of this work is to build hybrid indoor positioning and monitoring system that integrates smartphone sensors and Wi-Fi fingerprinting to achieve reliable, flexible and accurate indoor positioning system. The most influential factor that is affected by such a system is the presenting of the floor real map to the system which is very tedious, time consuming, complex processing task to be presented on a smartphone. This study has suggested and adopted an idea of virtual map which is generated automatically inside the smartphone. Then a mechanism that combines the APs fingerprint together with smartphone sensors, accelerometer, magnetometer and barometer readings, has been created to accurately determine the user position inside the floor map relative to well-known landmarks in the floor. In addition, the proposed mechanism lets the user watching her/himself moving on the virtual map that reflects the real floor map. Also the proposed system offers a monitoring activity which lets the administrator to watch and locate certain user inside the building.
