A discovery scheme based on carrier sensing in self-organizing Bluetooth Low Energy networks

Bluetooth Low Energy (BLE) gets lots of attention from researchers as one of the most prominent solutions for short range communications. But, the BLE still has many challenging issues which must be resolved before deploying it for the technologies. In this paper, an enhanced discovery mechanism is proposed for BLE devices to avoid collisions during advertisement process, so as to achieve lower latency as well as energy consumption. The proposed scheme is modeled and validated via analytical and simulation methods. The proposed mechanism has shown its effectiveness in avoiding unexpected long latency and much energy consumption by carrier sensing during discovery process in crowded BLE networks.
