UAV and IoT Integration: A Flying Gateway This paper introduces a new approach for Internet of Things. This approach is based on the integration of IoT and Unmanned Aerial Vehicles (UAVs) to establish a flying gateway that allows the extension of coverage of terrestrial IoT gateways. The approach is based on using several hardware devices as Arduino, Raspberry Pi boards and RAK 2445 board offering LoRa connectivity. This LoRabased gateway is deployed on board of a drone flying over IoT nodes to gather and transmit data to a LoRa server. This system will extend the coverage of the terrestrial LoRa gateways allowing to reach remote and rural areas.

Improving the Energy Efficiency of a LoRaWAN by a UAVbased Gateway The Internet of Things (IoT) devices and applications are spreading all over around us to become the cardiovascular infrastructure for the data of the cyberphysical systems of the future. The implementation of a reliable collection of telemetry data within various application domains, including medicine, safety, and security, industry, smart cities, or environmental monitoring, to name just a few, is among the major challenges still to be solved. Importantly, many of the use cases imply a huge geographic area span or operation in remote areas with limited infrastructure availability and poor reachability. To address these scenarios in this paper, we propose a combination of the two technologies the Low Power Wide Area Network (LPWAN) and the Unmanned Aerial Vehicles (UAVs). Specifically, we study the energy utility and the communication performance of introducing a UAVbased GW into an LPWAN based on the LoRaWAN technology. The results of our simulations show that a UAVbased GW enables to reduce the mean energy consumption for communication in the network by up to 59%. Depending on the UAV speed, the communication performance in terms of the packet delivery ratio can either increase or decrease by several percentage points.
