The edge clouds in mobile edge computing networks are isolate which may belong to different companies or organizations, and hence the communication, computation, and storage resources are not efficiently utilized. To solve this problem, we propose the resource-sharing model of edge clouds which is based on blockchain technology and auction game. In this model, the blockchain platform is regarded as the bridge of the resource sharing, composed of edge clouds, clouds, third-party spectrum and computation management, identity authentication institutions, etc. It is used to record the users’ transaction information and broadcast the intelligent terminals’ resource requirements to all edge clouds in the blockchain platform through smart contracts. Then, an optimization problem of the joint allocation of communication and computation resources is formulated to maximize the utility of intelligent terminals. And an efficient improved sealed second-price auction game is proposed to allocate communication and computation resources and determine the optimal price of resources under the intelligent terminals’ QoS constraints. Simulation results show that the model can effectively improve the system resources utilization and the successful transaction rate.

移动边缘计算网络中的边缘云是孤立的，可能属于不同的公司或组织，因此通信、计算和存储资源没有得到有效利用。为了解决这个问题，我们提出了基于区块链技术和拍卖博弈的边缘云资源共享模型。在该模型中，区块链平台被视为资源共享的桥梁，由边缘云、云、第三方频谱和计算管理、身份认证机构等组成，用于记录用户的交易信息和广播智能终端通过智能合约对区块链平台中所有边缘云的资源需求。然后，提出了通信和计算资源联合分配的优化问题，以最大化智能终端的效用。并提出了一种高效改进的密封次价拍卖博弈来分配通信和计算资源，并在智能终端的QoS约束下确定资源的最优价格。仿真结果表明，该模型能有效提高系统资源利用率和交易成功率。
