LoRaWAN End Nodes: Security and Energy Efficiency Analysis.

With the development of electronics and communication techniques, the interest in realizing sensor networks with a large number of end nodes is growing. The main idea is to install devices in remote locations without direct supervision, which requires an uninterrupted power supply and secure communication to the rest of the network. In this paper, an experimental comparative analysis of popular practical LoraWAN end nodes (WisNode RAK811 and Seeeduino SX1301) regarding energy consumption in different security modes, spreading factors, energy consumption in sleep/idle mode as well as the security keys extraction from memory was performed.
