Long-range data transmission on flying ubiquitous sensor networks (FUSN) by using LPWAN protocols

Abstract

Flying Ubiquitous Sensor Networks (FUSN) are one of the new Internet of Things applications. In such networks, Unmanned Aerial Vehicles (UAVs) are used to collect data from the wireless sensor nodes, located in hard to reach remote areas, and the subsequent data delivery to the Internet. For the stable operation, it is required to solve complex scientific problems, one of which is the choice of connectivity technologies for the data delivery from the sensor nodes to the gateway with the IP-network as well as the calculation of quality of service parameters. The paper considers the problem of data delivery with the terrestrial segment of the flying ubiquitous sensor network over long distances using repeater chain. As technology of interaction nodes terrestrial sensor network considered IEEE 802.15.4 (6LoWPAN protocol), and technology IEEE 802.15.4g is considered for UAV interaction (LoRaWAN protocol). In the study, analytical and simulation models of the flying ubiquitous sensor network have been developed. As a result of experiments with the simulation model, delay and packet loss were investigated, occurring in the all stations of transmission network at different data rates, and conclusions on the optimal data rate of the network were made.
