Cognitive Satellite Spectrum Management Scheme Based on the Cooperative Solidarity Values

With the rapid development of satellite services, the requirement for improving satellite spectrum efficiency has become significant, and attracted great attention from researchers and industry practitioners. Recently, cognitive satellite communication mechanism dynamically accesses idle bands of licensed spectrum while enabling spectrum sharing among satellite and terrestrial agents. In this paper, we propose a new spectrum management scheme for cognitive satellite communications. To effectively improve spectrum efficiency, the concepts of cooperative Solidarity values are adopted by compromising between productivity and solidarity principles. Based on two Solidarity values - Solidarity and Solidarity with size $p$ values, our two-step interactive game approach can leverage the full synergy that gives mutual advantage. The main novelty of our proposed scheme is to ensure the trade-off between marginalism and egalitarianism. Therefore, we can take various benefits in a rational way to reach a fair-efficient agreement under the dynamic changing satellite network environments. Finally, numerical results are provided to confirm the validity of our proposed approach, as well as quantitatively analyze the performance improvement by comparing with the existing protocols.
