Analysis of Wind Effect on Drone Relay Communications

Abstract

In this study, we realized a relay network using drones and analyzed the impact of the sway drone’s attitude on communication in a windy flight environment. Drones in flight act as y stations and communication among them is performed using radio equipment mounted In a windy environment, a directional antenna is used for relay communication among oid interference caused by the spread of radio waves in space and extend the relay distance. hen wind occurs during flight, the flying attitude of the drone inclines, which causes the e antenna to sway and the communication link to be disconnected, leading to a decrease nsmission speed. In this study, we statistically evaluated the pitch, yaw, and roll axes of a ugh wind tunnel experiments. Furthermore, the pattern of the swing angle of the drone ct to the wind speed was investigated using computer simulations to analyze the fluid nd theoretically analyze the swing of the drone. Based on these results, the transmission using a directional antenna was calculated. When the wind speed was 6.0 m/s, the deflection angle of the drone was 13◦ at maximum, and the average transmission speed by 33.3 Mbps. In this study, it was found that in communication between drones due to the wind, the transmission efficiency decreased depending on the sway angle of the aircraft.
