In this paper, we assess the efficiency of developed application layer automatic repeat-request (AL-ARQ) algorithm in UAV-assisted ad hoc network. We emulate HD video streaming using Ubuntu Mate 16 virtual machines, B.A.T.M.A.N. routing protocol, and NS-3 simulation tool. We cope with congestions at the relay node using COPE-like network coding implemented in the routing protocol. The relay node could be stationary like a copter or moving in circle like a fixed-wing drone. AL-ARQ demonstrated packet loss ratio PLR _ave <; 0.01 for both scenarios for distances between nodes up to 400 meters. In both cases higher PLR _ave caused more retransmissions at the application layer and gave more opportunities for network coding to encode packets at the relay node.
