Space Occupancy through BLE Dynamic Broadcasting

Internet of Things (IoT) merges different technologies to provide the needed infrastructure for an adequate inter-device connection and data exchange, with Bluetooth Low Energy (BLE) being one of the latest acquisitions. The use of BLE beacons offers a straightforward approach to broadcast information to any device being in the coverage zone and able to process such signal. Instead of this static solution, in this paper, we face an alternative approach that, combining both Wi-Fi and BLE beacon technologies, is able to dynamically adapt the information being broadcast depending on the particular devices in the coverage area. Taking advantage of the beacon device communications, we propose to monitor the space occupancy throughout the study area (typically inside a building) by following the beacon device data exchange. This information would be later used to improve space analysis. As a proof of concept, we have conducted an experiment inside a faculty to check the potentiality of the proposal, obtaining promising results.

Simulation of a Broadcasting Method Based on Busy Tone

When the receiving nodes are uncertain or the topology of the ad hoc network is high dynamic, broadcasting is an effective data dissemination method. In this research, a broadcasting method based on busy tone is modeled and implemented with the network simulation platform OPNET, and the performance of the broadcasting method is analyzed based on experimental results. Experimental results show that, in the network with various load, performance of the broadcasting method based on busy tone is good.
