The demand for frequency is continuously increasing owing to the growth of wireless communication devices and the development of network technology. To share frequency effectively in a limited frequency resource environment, studies to develop spectrum-sharing technology should be conducted. In this study, a blockchain-based spectrum- sharing system, in which various types of users can efficiently share spectrum in dense networks, is proposed. Furthermore, a method to apply game theory to obtain cooperation from users who do not participate in the spectrum-sharing system is studied. When the simulation was conducted based on game theory, the proposed blockchain-based spectrum-sharing technique was simulated by using the tit-for-tat (TFT) strategy, in which the system cooperates with the users if the users collaborate and the system does not cooperate with the users if the users do not collaborate. Simulations show that there are more than a certain percentage of users who use the TFT strategy, and if users are encouraged to change their sharing strategy on a regular basis, they can provide more efficient spectrum sharing than traditional centralized methods. It was confirmed that this technique can improve spectrum sharing by 55.1% or more through optimization.
