Algorithm for ensuring the minimum power consumption of the end node in the LoRaWAN network

Abstract

The paper approves the relevance of the development of theoretically justified tools aimed at power consumption minimization in the data transmission network of the LoRa WAN standard. Such a network is used to monitor various objects in a distributed system of the Internet of things. LoRa WAN end nodes have autonomous power supplies, for which energy costs saving is important. The paper presents expressions for estimating the power consumption of a LoRa WAN end node. Based on the results of computational experiments, a database was formed containing signal attenuation values and their corresponding recommended values of transmitter power and spectrum spreading factor. This database is used in the algorithm for ensuring the minimum power consumption of the end node.
