摘要: 无线电资源交易发生在MTC网关(MTC Gateway MTCG)和LTE用户之间.根据基于联盟区块链的空闲无线电资源交易来建立MTCG之间的信用度.在多个授权的本地基站(Base Station BS)上建立了一个联盟区块链,用于公开审计和共享交易记录.资源交易记录在加密后上传到BS.在交易记录通过审查和共识过程之后,新区块被存储在BS上,并且可以由MTCG,LTE用户和连接到联盟区块链的BS进行公开访问.为了最大化系统的利益,支持频繁的资源交易,提出了一种基于信用贷款的支付方案,并给出了相应的最优定价策略.

Abstract: The radio resources trading happened between the MTCGs and the LTE users.The credit degrees are built among the MTCGs according to the free radio resources trading based on the consortium blockchain.A consortium blockchain has been established on the BSs for publicly auditing and sharing of transaction records without depending on the trusted third parties.The resource transaction records are uploaded to the BS after encryption.After the transaction records pass the review and consensus process,the new blocks are stored on the BSs that can be accessed publicly by MTCGs,LTE users and the BSs connected to the consortium blockchain.In order to maximize the benefits of the system and support frequent resource transactions,a credit-based payment scheme and the corresponding optimal pricing strategy are proposed.

Key words: consortium blockchain, credit loan, credit radio resources trading, credit degrees
