摘要: 随着终端设备智能化发展与设备到设备(D2D)通信技术的逐渐应用,终端设备可以通过直连链路进行资源共享.为提升网络边缘整体服务能力,提出了一种基于区块链的D2D辅助的多接入边缘计算资源共享架构(BD-MEC).在BD-MEC下,综合考虑时延、能耗和支付开销等因素,设计了一种基于博弈论的多用户卸载方案,以满足不同用户的服务需求.其次,针对拒绝服务或付款等恶意行为,提出了一种基于智能合约的资源共享协议与争议事件处理方法,利用区块链来强制共享双方遵守资源共享协议,以实现安全的资源共享.仿真结果表明,BD-MEC能有效地降低计算任务的时延、能耗和支付开销.

Abstract: With the intelligent development of terminal devices and the growing applications of device-to-device(D2D)communication technology,terminal devices can share resource through a direct link. To improve the overall service capabilities of the network edge,a blockchain-based D2D-assisted multi-access edge computing architecture(BD-MEC)for resource sharing is proposed. In BD-MEC,considering the factors of the delay,energy consumption,and payment overhead,an offload decision-making based on game theory for multi-user scenario is proposed to meet the needs of different users. Moreover,in view of the malicious behaviors such as denial of service or payment,a smart contract-based resource sharing protocol and dispute handling method are proposed, which uses the blockchain to force the sharing parties to comply with the resource sharing protocol to achieve safe resource sharing. Simulations show that BD-MEC can effectively the reduce delay,energy consumption,and payment of computing tasks.
