INDOOR LOCATION OF A MOBILE DEVICE BASED ON BLUETOOTH TECHNOLOGY

Abstract

Global Positioning System (GPS) is a commonly used system for controlling sensors and figuring out the location of devices in outdoor areas, and is very common. But because of reflections of the signals due to walls and furniture presence and various other factors causing signal attenuation within a house, it is not effective for indoor localization. WLAN, Bluetooth, RFID, Wi-Fi are therefore used to locate computer locations that are held inside a building by individuals. This paper introduces a new framework focused on Bluetooth technologies for the indoor positioning of a mobile device. For the positioning system and for accessing the network, Bluetooth network control points are used. The position is generated by means of the signal intensity obtained from certain points of entry. The signal energy is calculated by a mobile device and transmitted to a central server which calculates the position of the signal. Since the position is generated on a central server, some type of algorithm may be considered to approximate it. The positioning scheme also uses a prior study of the scene by considering a diagram of the signal strengths obtained.
