Considering the uncertainty of the forwarding delay of deterministic transmission services in UAV (Unmanned Aerial Vehicle) networks caused by the dynamic change of wireless channel in UAV cluster network, a deterministic transmission services scheduling scheme for UAV cluster networks is proposed. Firstly, a channel fading loss model in a highly dynamic UAV cluster network is established; Secondly, based on this model, the network is partitioned into several segments of stable network from the time domain; Finally, an optimization objective function model with minimum average jitter is constructed to ensure the deterministic transmission services scheduling in the UAV cluster network, and is solved by an optimization genetic algorithm. Simulation results show that, compared with other schemes, the average jitter of the proposed scheme is not higher than 60µs, which can effectively provide transmission jitter certainty for deterministic transmission.
