摘要:
提出了一个 3 层的物联网边缘计算的区块链云架构以及基于区块链技术的分布式云服务模型,构建了低成本、安全、按需访问的 IoT 智能计算基础框架。边缘计算节点使用 SDN 控制器,将计算资源边缘化,降低网络中的数据流量,并在物联网设备之间实现最小的端到端延迟和最优的计算资源利用。同时,提出了此架构下的云端数据保护机制,使用移动代理技术将分布式虚拟机代理模型部署在云中,让多租户相互协作以确保数据的完整性验证。虚拟机代理模型与默克尔哈希树生成文件相对应的唯一哈希值,通过区块链上的智能合约来实时监视数据变化,遇异常时向用户发出数据篡改警告消息,并用“质询 响应”模式构建云数据完整性验证方案。最后,在某电网公司的数字化基建( BIM )环境下部署了所提的区块链分布式云架构,通过实验分析了延迟、客户端响应时间和文件操作性能。实验结果表明,与集中云架构比较起来,所提方法具有更快的响应时间、更高的吞吐量和更小的文件操作开销。
Abstract:
A three-layer blockchain cloud architecture for IoT edge computing is proposed.Then a distributed cloud service model based on blockchain , and a low-cost , secure , on-demand accessing IoT intelligent computing framework are constructed.We use SDN controllers for the edge computing nodes to marginalize computing resources , reduce data traffic in the network , and achieve the minimum end to end delay and optimal utilization of computing resource among IoT devices.At the same time , a cloud data protection mechanism under this architecture is also proposed , which uses mobile agent technology to deploy the distributed virtual machine agent model in the cloud , so that multi-tenants can cooperate with each other to ensure data integrity verification.The unique hash value on the blockchain corresponding to the file which is generated by the virtual machine and Merkel hash tree monitors the data changes in real time through the smart contract on the blockchain , sends a warning message of data tampering to the user in case of exceptions , and builds a cloud data integrity verification scheme with the “ query response ” mode.Finally , the proposed model is deployed in the building information modeling ( BIM ) environment of a power grid company , and the latency , response time and file operation performance are analyzed by some experiments.The experimental results show that the proposed method has less response time , higher throughput and lower file operation cost than the centralized cloud architecture.
