Abstract: Nowadays, many investigators have examined the effects of Bluetooth low energy (BLE) for a wide range of applications due to its low-cost and low-power characteristics. Hence, performance improvement during the discovery process has become one of major concerns. In BLE networks, advertisement interval of advertiser directly influences the performance, such as discovery latency and energy consumption. Frequent transmissions of advertising packet may result in collisions and serious energy consumption. On the contrary, larger advertisement interval may lead to delayed device discovery. In this paper we propose an algorithm to dynamically adjust its advertisement interval considering the network conditions based on a carrier sensing (CS) scheme. Simulation results show that the proposed algorithm has outstanding performance compared with basic CS scheme and BLE standard in crowded BLE networks.

Keywords: BLE; Bluetooth low energy; device discovery; IoT; internet of things; dynamic advertisement interval.
