Hierarchical spectrum sharing method and system for uav swarm

Abstract

This invention discloses a hierarchical spectrum sharing method and system for unmanned aerial vehicle (UAV) swarms, relating to the field of electromagnetic spectrum management technology. The method includes: constructing the available spectrum space for each UAV swarm network and determining the frequency demand information for each UAV swarm network; modeling the spectrum planning problem as a bilateral matching problem of spectrum resource block supply and demand; calculating the preference sequence of each spectrum resource block and the preference sequence of each UAV swarm network based on the bilateral matching problem and the available spectrum space of each UAV swarm network; and determining the spectrum resource block matched to each UAV swarm network according to the hierarchical spectrum resource sharing strategy and the preference sequence, ensuring that the UAV swarm network can obtain suitable spectrum resources in different spectrum environments, achieving efficient spectrum sharing and utilization of the UAV swarm network spectrum. This method can be widely applied to electromagnetic spectrum management, UAV swarm network spectrum resource planning, and other scenarios.
