摘　　要：本文提出了一种基于区块链和博弈论的频谱共享方案。与使用集中式平台的传统频谱共享方法不同,该方案利用区块链的去中心化和高度信任优势,让运营商共享自由频谱并提高利用率。该频谱共享系统建立在联盟区块链上,运营商可以在其中直接交易频谱。联盟区块链用于认证等待加入的成员,记录所有的交易信息,并确保其不会被篡改。此外,该方案建立了博弈模型,运营商可使用博弈论在彼此之间实现共享频谱的纳什均衡,达到最优的共享策略。仿真结果表明,该方案可以有效提高运营商的频谱利用率,增加运营商的收入。A spectrum sharing scheme based on blockchain and game theory was proposed.Different from the traditional spectrum sharing method using centralized platform,this scheme made use of the advantages of decentralization and high trust of blockchain to enable operators to share free spectrum and improve utilization.The spectrum sharing system was built on the alliance blockchain,where operators could directly trade spectrum.The federated blockchain was used to authenticate members waiting to join,record all transaction information,and ensureed that they will not be tampered.In addition,a game model was established.Operators could use game theory to achieve the Nash equilibrium of sharing spectrum between each other to achieve the optimal sharing strategy.The simulation results showed that the scheme could effectively improve the spectrum utilization of operators and increase their revenue.
