Efficient tracking of industrial equipments using a wi-fi based localization system

Wi-Fi localization system based on RSSI is the best candidate for indoor device-tracking in comparison with other systems based on GPS, RFID, infrared and image processing. This paper presents Wi-Fi localization system based on a Wi-Fi routers´ network for tracking the device position indoors such as buildings, university campus, skyscrapers and other places where Wi-Fi is present including shopping malls. Our system consistently collects the current location and status of the tracked devices and sends them periodically to the users´ central office for further processing and display. If there are any unexpected changes of the tracked device´s position, an immediate notification is sent via email to the administrator for security purposes. The system operates real-time with high accuracy. Contributions are made in software development and Wi-Fi tags attachments design.
