Nowadays, Internet of Things (IoT) is one of the most current trends in the development of telecommunications. So many technologies have appeared with the aim of providing communication between the IoT devices. In this area, one of the newest technologies is LoRa, which represents the features of long-range transmission and energy savings. This article discusses the main characteristics of LoRa technology and based on which the method of organization mesh topology is proposed for the interaction of IoT devices. The proposed method is implemented on a complex hardware platform and the route search time depending on the number of nodes in the network is estimated.
