Game-Theoretic Incentive Mechanism for Spectrum Sharing in UAV Swarms: An Innovative Hybrid Access Model

In order to alleviate the shortage of spectrum resourceswe proposed an incentive mechanism for spectrum sharing among Unmanned Aerial Vehicle (UAV) swarms, leveraging the Stackelberg game theoretical framework. The UAV-to-Base Station (U2B) links, act as the leaders, share spectrum resources with the UAV-to-UAV (U2U) links, who act as followers. In this paper, we designed a hybrid overlay-underlay spectrum access mode, effectively tackling the intricate problem of inter-user interference. Finally, we introduce a utility-maximizing matching scheme. The simulation results indicate that our method can effectively enhance system utility and achieve more efficient spectrum sharing.
