Abstract:The electromagnetic spectrum is a strategic resource and currently the most optimal medium for information transmission, serving as the bridge that supports the integration of physical and digital realms thereby fostering swarm intelligence. However, in view of the core challenges such as the dynamic complexity of the electromagnetic spectrum space environment, partial unobservability and high heterogeneity of group users, future electromagnetic information systems need to be more efficient and intelligent. This paper proposes the concept of swarm spectrum intelligence and the swarm spectrum intelligence cognitive paradigm oriented towards group integration, coordination and inspiration. On the one hand, by integrating swarm intelligence algorithms, cooperative control technologies, and service application systems, the swarm spectrum intelligence framework aims to harness the swarm wisdom, the boost efficiency through quantitative measures, and the leverage emergent effects as fundamental technological principles. On the other hand, by addressing issues of perception, utilization, and control within the swarm electromagnetic spectrum, the proposed framework ultimately strives to achieve precise spectrum sensing, efficient spectrum utilization, and dynamic spectrum management. These advancements are poised to lay a solid foundation for the development of interconnected, secure, and efficient smart cities.
