Abstract
The recent publication of the Bluetooth Mesh standard is a remarkable milestone in the evolution of Bluetooth Low Energy (BLE). As a new technology in the Internet of Things (IoT) market, it is crucial to investigate the performance of Bluetooth Mesh. However, while a fundamental feature of Bluetooth Mesh is its suitability for energy-constrained devices, this aspect has not yet been properly considered in the literature. In this paper, we model the current consumption, lifetime and energy cost per delivered bit of a battery-operated Bluetooth Mesh sensor node. The model is based on measurements performed on a real hardware platform. Evaluation results quantify the impact of crucial Bluetooth Mesh parameters. Among others, we have found that a sensor device 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, whereas the asymptotic lifetime is 21.4 months.
Highlights
Bluetooth Low Energy (BLE) is a low-power wireless technology that has become a cornerstone for the Internet of Things (IoT) [1,2]
We have presented analytical models on important energy performance parameters of a battery-operated Bluetooth Mesh-Low Power Node (BM-LPN), such as current consumption, lifetime and energy consumed per delivered bit
The models take into account the influence of Bluetooth Mesh parameters, such as ReceiveWindow and PollTimeout, as well as the data message rate
Summary
Bluetooth Low Energy (BLE) is a low-power wireless technology that has become a cornerstone for the Internet of Things (IoT) [1,2]. BLE was originally designed to create star-topology networks, where devices with significant resource constraints are connected via a direct link to a potentially less constrained central device An example of this paradigm is a set of battery-operated sensors that provide their readings to a smartphone that centralizes sensor data collection. We model the energy performance of a low power device (a battery-operated sensor) that makes use of the energy saving feature provided by Bluetooth Mesh. We call such a device a Bluetooth Mesh-Low Power Node (BM-LPN).
