Real Time Asset Tracking using BLE Beacons

Abstract

BLE Beacon stands for Bluetooth Low Energy Beacon. Often used for asset tracking and indoor positioning, the beacons can communicate with receivers and the user through Bluetooth. The system designed utilizes BLE beacons to primarily measure Random Signal Strength (RSSI) values of the beacon with respect to the receiver. These values can further be used to calculate the approximate distance of the beacon from the receiver. The RSSI values are communicated to the computational interface from the receiver using the MQTT protocol. The distance is calculated via a formula derived using linear regression. The approximate position of the beacon in a given space is calculated using a hybrid version of the algorithm of trilateration.
