Blockchain and timely auction mechanism-based spectrum management

The rapid development of 5G/B5G communication networks and the exponential growth of next-generation wireless devices require more advanced and dynamic spectrum management and control architecture. Dynamic spectrum management and control based on blockchain is efficient and robust, but the cost of traditional consensus mechanisms is too high. In this paper, we propose anew spectrum management and control architecture based on blockchain and deep reinforcement learning, which proposes anew energy-saving consensus mechanism called proof of hierarchy to encourage blockchain users to perform spectrum sensing and detect spectrum violations. Meanwhile, we propose a timely auction mechanism based on deep reinforcement learning for dynamic spectrum management, achieving secure, efficient, and dynamic allocation of spectrum resources. Through intelligent resource allocation and trusted transaction mechanism, efficient spectrum management is realized to improve spectrum utilization and alleviate the shortage of spectrum resources. The simulation verifies the effectiveness of the proposed architecture. We construct a spectrum management scenario and compare it with the traditional spectrum management method. The experimental results show that the proposed architecture can allocate spectrum resources more efficiently and provide a better user experience.
