The paper approves the relevance of the development of theoretically justified tools aimed at power con-sumption 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 au-tonomous 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 exper-iments, 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 ensur-ing the minimum power consumption of the end node.
