The fifth generation (5G) wireless networks are on the way to be deployed around the world. The 5G technologies target to support diverse vertical applications by connecting heterogeneous devices and machines with drastic improvements in terms of high quality of service, increased network capacity and enhanced system throughput. However, 5G systems still remain a number of security challenges that have been mentioned by researchers and organizations, including decentralization, transparency, risks of data interoperability, and network privacy vulnerabilities. Furthermore, the conventional techniques may not be sufficient to deal with the security requirements of 5G. As 5G is generally deployed in heterogeneous networks with massive ubiquitous devices, it is quite necessary to provide secure and decentralized solutions. Motivated from these facts, in this paper we provide a state-of-the-art survey on the integration of blockchain with 5G networks and beyond. In this detailed survey, our primary focus is on the extensive discussions on the potential of blockchain for enabling key 5G technologies, including cloud computing, edge computing, Network Function Virtualization, Network Slicing, and D2D communications. We then explore and analyse the opportunities that blockchain potentially empowers important 5G services, ranging from spectrum management, data sharing, network virtualization, resource management to interference management, federated learning, privacy and security provision. The recent advances in the applications of blockchain in 5G Internet of Things are also surveyed in a wide range of popular use-case domains, such as smart healthcare, smart city, smart transportation, smart grid and UAVs. The main findings derived from the comprehensive survey on the cooperated blockchain-5G networks and services are then summarized, and possible research challenges with open issues are also identified. Lastly, we complete this survey by shedding new light on future directions of research on this newly emerging area.

适用于5G和其他网络的区块链:最新调查

第五代(5G)无线网络正在全球范围内部署。5G技术旨在通过连接异构设备和机器来支持多样化的垂直应用,这些服务在服务质量,增加的网络容量和增强的系统吞吐量方面都得到了显着改善。然而,5G系统仍然是研究人员和组织提到的许多安全挑战,包括分散,透明,数据互操作性风险和网络隐私漏洞。此外,传统技术可能不足以满足5G的安全要求。由于5G通常部署在具有大量无所不在设备的异构网络中,因此非常有必要提供安全且分散的解决方案。基于这些事实,在本文中,我们提供了有关将区块链与5G网络及其他网络集成的最新技术调查。在这份详细调查中,我们的主要重点是就区块链在支持关键5G技术(包括云计算,边缘计算,网络功能虚拟化,网络切片和D2D通信)中的潜力进行的广泛讨论。然后,我们探索并分析区块链可能为重要5G服务提供支持的机会,从频谱管理,数据共享,网络虚拟化,资源管理到干扰管理,联合学习,隐私和安全性提供。区块链在5G物联网中的最新应用也得到了广泛的使用案例领域的调查,例如智能医疗保健,智能城市,智能交通,智能电网和无人机。然后总结了对合作的区块链5G网络和服务进行的全面调查得出的主要发现,并确定了存在开放性问题的可能研究挑战。最后,我们通过阐明这一新兴领域的未来研究方向来完成本调查。
