  Abstract

This paper proposes a relay UAV defect recovery scheme to minimize network communication gap time due to the occurrence of a relay UAV defect. The proposed scheme synchronizes the data of the relay UAV by placing the backup UAV within the coverage of the UAV mesh network. When a defect occurs in the relay UAV, the backup UAV moves to the defect relay UAV area and is disposed. The disposed backup UAV enables communication to be recovered by performing an existing defect relay UAV mission. In addition, it is intended to reduce energy consumption by adjusting the message communication interval between the relay UAV and the backup UAV. As a result of evaluating the performance of the recovery scheme in the simulated environment, it was confirmed that the packet loss was lower than that of the transmission power control technique through Hello messages. In addition, through interval control, the appropriate power saving mode time was confirmed by comparing the data throughput by time.
