区块链无线接入网:面向未来移动通信的新架构

Blockchain radio access network:a new architecture for future mobile communications

移动通信技术的快速发展与移动网络的持续扩张使得各类无线资源日趋紧张,下一代移动通信系统设计亟需引入新思路、新构架。区块链无线接入网是一种基于区块链的新型分布式网络架构。作为区块链使能的新一代无线接入网,区块链无线接入网将区块链底层技术与移动通信系统进行了深度融合,面向未来移动通信进行了全新的模式探索。简要介绍了区块链无线接入网的设计原理与工作流程,给出了区块链无线接入网在多类场景和需求驱动下的技术方案,并进一步分析了区块链无线接入网的核心安全指标性能。还为区块链无线接入网设计了专有框架,并实现了核心模块,实际测试验证了区块链无线接入网系统的运行性能。测试表明,区块链无线接入网在多子网融合环境下具有显著的吞吐量优势,相比于一般区块链架构,区块链无线接入网还拥有更低的服务部署时延,并能通过动态参数调整在安全指标与服务时延间取得良好平衡。

With the rapid development of mobile communications and continuous network expansion,wireless resources become increasingly scarce.Based on the blockchain,the blockchain radio access network(B-RAN)has recently emerged as a promising architecture for the next generation mobile communication system.Via in-depth merging of blockchain and wireless communication technologies,the B-RAN presents a new paradigm to design future mobile networks.This paper briefly introduces the basic concept and workflow of the B-RAN,and provides several technical solutions for the B-RAN in order to satisfy different scenarios and needs.Furthermore,the security performance of the B-RAN is theoretically analyzed.This paper also designs a dedicated framework of the B-RAN and implements its core modules to test its practical performance.The test results show that the B-RAN has a noteworthy advantage in throughput under the scenario of multiple subnetworks.Compared with other blockchain architectures,the B-RAN has a significantly lower latency of service deployment and is able to achieve the balance dynamically between its security level and service latency.
