Abstract:Utilizing BLE beacons and gateways to track assets can enable the optimization of logistical processes through data-driven insights. This research determines the positions and orientations of BLE gateways that ensure maximum coverage area when deployed in the aviation industry. We propose a Particle Swarm Optimization algorithm, called PSOP, to determine the optimal positions. PSOP maximizes the number of beacons in range of at least one gateway. A combination of the Link Budget and the Log Distance Path Loss model is used to determine the range of a gateway. We characterized the parameters used in these calculations via measurements. The path loss exponent is determined for various zones inside an airplane hangar. Besides, the antenna pattern, RSSI at one meter distance and minimum required RSSI for data trans- mission parameters have been determined. The algorithm uses these parameters to find the optimal BLE gateway positions. The algorithm was able to position the gateways for a specific setup such that 100% of the sensors were in range of at least one gateway.
