基于区块链的频谱管理:综述与初步探讨

Blockchain-based spectrum management:survey and preliminary discussions

随着第五代移动通信(5G)的商用以及工业互联网、人工智能、增强现实/虚拟现实和车联网等新应用的快速发展,当前集中式的频谱管理模式将面临极大的挑战(频谱资源紧缺、安全性威胁、维护费用高等).区块链自身的去中心化、时序数据、集体维护和安全可信等特点对于解决当前频谱管理面临的问题具有天然优势.本文首先分析了当前集中式频谱管理方式中的诸多问题,归纳了区块链应用于频谱管理的优势,并总结了基于区块链的频谱管理研究现状.然后,对基于区块链的频谱管理模式和工作流程进行了初步探讨.最后,总结了基于区块链的新型频谱管理系统架构、频谱感知与频谱交易所涉及的一系列新问题.

With the commercialization of the fifth-Generation(5G)mobile communications and the rapid development of new applications such as industrial Internet of things,artificial intelligence,augmented reality/virtual reality and Internet of vehicles,the current centralized spectrum management encounters various challenges(e.g.,spectrum shortage,security threat,high maintenance cost).Blockchain embraces natural advantages to solve the problems in current spectrum management owing to its characteristics such as decentralization,time-series data,collective maintenance and high security.Firstly,this paper analyzed the problems in current centralized spectrum management and the advantages of the blockchain-based spectrum management,and then the research progress of blockchain-based spectrum management was summarized.Secondly,the blockchain-based spectrum management mode was discussed.Lastly,the problems and open issues in blockchain-based spectrum management architecture,spectrum sensing and spectrum trading were summarized.
