The field of unmanned aerial vehicle (UAV)-assisted networking and spectrum management is witnessing significant developments, driven by the need for efficient and reliable data transport in dynamic environments. Researchers are exploring innovative approaches to optimize data routing, resource allocation, and interference management in UAV-based networks. Notably, the integration of machine learning and optimization techniques is enabling the development of more efficient and adaptive algorithms for spectrum allocation and UAV trajectory planning. Furthermore, the use of Lyapunov optimization and diffusion-based reinforcement learning is improving the performance of UAV-assisted vehicular networks. The application of beamforming and integrated sensing and communication (ISAC) technology is also being investigated for multi-UAV networking and emergency communication scenarios. Additionally, novel UAV swarm-based phased array antenna systems are being designed and experimentally validated, offering a practical and scalable platform for next-generation airborne communications and remote sensing applications.
