Maritime Multi-relay Communications based on UAV Trajectory Adjustment and Dual Q-learning

The 6G has the potential to make a leap in the quality of marine networks. Based on the characteristics of 6G, this paper designs a system of marine wireless communication network. This system uses multiple unmanned aerial vehicles as relay nodes. Using a UAV trajectory adjustment algorithm based on dual Q-learning, the UAVs can improve network performance by adjusting their flight stereo-attitude in real time. The experiment is carried out on a prototype with trace file. The numerical results show our system and UAV trajectory adjustment algorithm can achieve an advantage in terms of realtime data rate and adaptability of marine environment.
