Integrated Spectrum Management Architecture Based on Spatial Spectrum Map in Multi-UAVs Networks

To solve the issue of the difficulty in spectrum management to meet the requirements of large-scale unmanned aerial vehicles (UAVs) networks, an integrated architecture for intelligent spectrum management of multi-UAVs networks based on spatial spectrum map is proposed, which innovatively separate the control link and the information transmission link. A new spectrum guarantee mode that combines static spectrum planning and dynamic spectrum allocation is adopted in spectrum management architecture. It can achieve a closed-loop process of spectrum management, sensing, and decision-making through integrated design of spectrum map updating, joint planning of task and spectrum, and spectrum sharing and collaboration. In the proposed mode, the planned spectrum will be used for the telemetry and remote-control links by the static spectrum allocation. The business link is allocated the spectrum by a dynamic spectrum sharing that jointly plans the task and spectrum of UAVs, which can expand the spectrum capacity of UAVs. Then the joint planning method of task and spectrum, and the spectrum sharing and collaboration are presented based on spatial spectrum map. Simulation results show that these proposed methods can obtain better performance.
