面向区块链无线接入网络的建模与分析OA
Blockchain-enabled radio access network:modeling and analysis
区块链无线接入网络(B-RAN)是一种面向可信移动通信的分布式网络架构,通过将区块链与无线网络深度融合,突破网络间信任壁垒,以安全可信的方式实现无线资源共享、移动设备接入与跨网络负载均衡.针对B-RAN架构与工作流程,系统性梳理了刻画B-RAN的接入模型与分析方法.首先,通过排队论建立了基于区块链的无线接入模型,并总结不同排队模型的差异与内在关联.然后,针对B-RAN的快速可信接入方法,建立博弈模型,并深入分析无线信道不确定性对博弈合作条件的影响;针对B-RAN的免授权哈希接入机制,基于马尔可夫模型分析其性能,并探讨了基于区块链的跨网络负载均衡.最后,仿真结果展示了B-RAN在不同场景下的性能,并验证了对应数学模型的有效性.
Blockchain radio access network(B-RAN)is a distributed network architecture for trustworthy telecommuni-cations.By integrating blockchain with wireless networks and breaking trust barriers,B-RAN enables secure and trust-worthy wireless resource sharing,mobile device access,and cross-network load balancing.With a focus on the architec-ture and workflow of B-RAN,the access models and analysis methods used to characterize B-RAN were systematically reviewed.First,blockchain-enabled wireless access model was established via queuing theory,and the relations and dif-ferences among various queuing models were summarized.Then,for B-RAN's fast trustworthy access method,the game model was established,and the impact of wireless channel uncertainty on the game cooperation conditions was analyzed.For B-RAN's grant-free hash access mechanism,the Markov model was used to analyze its performance,and blockchain-enabled cross-network load balancing was discussed.Finally,simulation results demonstrate the performance of B-RAN across different scenarios and validate the effectiveness of the corresponding mathematical models.
