![]() However, their work does not consider energy-related performance parameters. ![]() provide an overview on Bluetooth Mesh and a thorough investigation of the Round Trip Time (RTT) in this technology, which is carried out both analytically and also experimentally. We also discuss the applicability and limitations of Bluetooth Mesh as an IoT technology, considering the power supply requirements that stem from the Bluetooth Mesh architectural design.īaert et al. We have found that a BM-LPN running on a simple 235 mAh battery, and sending a data message every 10 s, can achieve a lifetime of up to 15.6 months with the considered hardware platform, whereas the asymptotic lifetime is 21.4 months. Our models, which are derived from measurements performed on real hardware, allow us to quantify the impact of critical Bluetooth Mesh parameters, the BM-LPN data message rate, and the frame loss rate, on BM-LPN energy performance. We develop analytical models for three important energy performance parameters: the BM-LPN average current consumption, the theoretical lifetime of a battery-operated BM-LPN, and the energy consumed per each user data bit delivered by the BM-LPN. We call such a device a Bluetooth Mesh-Low Power Node (BM-LPN). In this paper, we model the energy performance of a low power device (more specifically, a battery-operated sensor) that makes use of the energy saving feature provided by Bluetooth Mesh.
