Energy Performance Analysis of LoRaWAN End Device with Autonomous Power Supply

In recent years, LoRaWAN (LongRange Wide area Network) has attracted the attention of the community dealing with sensor networks and communications and their application in the Internet of Things (IoT) and Industrial IoT. It is a key technology in building a Low-Power Wide Area Network (LPWAN) because it provides reliable low-power data transmission. An essential point and challenge in the application of this technology is ensuring maximum autonomy of LoRaWAN end devices by achieving the lowest possible energy consumption in sleep and active mode and the search for efficient power supply solutions. In this paper, a solution for autonomous powering of a LoRaWAN end device with a photovoltaic panel and optimization of energy consumption in different operating modes is proposed and investigated. A system has been developed for monitoring, analysis and visualization of end device consumption.
