【Abstract】The evolution of the Industrial Internet of Things (IIoTs) greatly increases the volume of data generated by the connected IIoT devices. IIoT data are playing an increasingly important role in various industrial sectors. IIoT data sharing helps enterprises make better production decisions and respond to market changes timely. However, the distrust among IIoT entities and IIoT entities' distrust of data-sharing platforms may hinder the realization of data sharing. In this article, a decentralized IIoT data-sharing scheme based on blockchain and edge computing is proposed. A Proof of Storage and Transmission (PoST) consensus mechanism is proposed to meet data storage and transmission requirements of data owners in IIoT data-sharing networks. Based on the manufacture ties of data owners, shared data request probabilities are derived. The IIoT data sharing interactions between data owners and edge devices are modeled as a multiple-leader and multiple-follower Stackelberg game. The alternating direction method of multipliers (ADMMs) algorithm is used to obtain the optimal IIoT data sharing solutions in a distributed manner. Simulation results show that compared with the cooperative scheme, the total profit of edge devices is maximally increased by 59%, and the total utility of data owners is maximally increased by 52%.

【标题】基于区块链的 IIoT 数据共享：一种多领导者多跟随者 Stackelberg 博弈方法
【摘要】工业物联网 (IIoT) 的发展极大地增加了连接的 IIoT 设备生成的数据量。 IIoT 数据在各个工业领域发挥着越来越重要的作用。 IIoT数据共享帮助企业做出更好的生产决策，及时响应市场变化。然而，IIoT 实体之间的不信任以及 IIoT 实体对数据共享平台的不信任可能会阻碍数据共享的实现。本文提出了一种基于区块链和边缘计算的去中心化工业物联网数据共享方案。为了满足 IIoT 数据共享网络中数据所有者的数据存储和传输需求，提出了一种存储和传输证明 (PoST) 共识机制。基于数据所有者的制造关系，推导出共享数据请求概率。数据所有者和边缘设备之间的 IIoT 数据共享交互被建模为多领导者和多跟随者 Stackelberg 博弈。乘法器交替方向法 (ADMMs) 算法用于以分布式方式获得最优的 IIoT 数据共享解决方案。仿真结果表明，与合作方案相比，边缘设备的总利润最大提高了59%，数据所有者的总效用最大提高了52%。
