Driven by advanced 5G cellular systems, mobile edge computing (MEC) has emerged as a promising technology that can meet the energy efficiency and latency requirements of IoT applications. Edge service migration in the MEC environment plays an important role in ensuring user service quality and enhancing terminal computing capabilities. Application services on the edge side should be migrated from different edge servers to edge nodes closer to users, so that services follow users and ensure high-quality services. In addition, during the migration process, edge services face security challenges in an edge network environment without centralized management. To tackle this challenge, this paper innovatively proposes a blockchain-based security edge service migration framework, Falcon, which uses mobile agents different from VM and container as edge service carriers, making migration more flexible. Furthermore, we considered the dependencies between agents and designed a service migration algorithm to maximize the migration benefits and obtain better service quality. In order to ensure the migration of edge services in a safe and reliable environment, Falcon maintains an immutable alliance chain among multiple edge clouds. Finally, the experimental results show that “Falcon” has lower energy consumption and higher service quality.

Falcon：MEC中基于区块链的边缘服务迁移框架

在先进的5G蜂窝系统的推动下，移动边缘计算（MEC）已成为一种有前途的技术，可以满足IoT应用的能效和延迟要求。MEC环境中的边缘服务迁移在确保用户服务质量和增强终端计算能力方面起着重要作用。边缘端的应用程序服务应从不同的边缘服务器迁移到更靠近用户的边缘节点，以使服务跟随用户并确保高质量的服务。此外，在迁移过程中，边缘服务在没有集中管理的情况下在边缘网络环境中面临安全挑战。为了应对这一挑战，本文创新性地提出了基于区块链的安全边缘服务迁移框架Falcon，它使用不同于VM和容器的移动代理作为边缘服务载体，从而使迁移更加灵活。此外，我们考虑了代理之间的依赖关系，并设计了一种服务迁移算法以最大化迁移收益并获得更好的服务质量。为了确保在安全可靠的环境中迁移边缘服务，Falcon在多个边缘云之间维护了一个不变的联盟链。最后，实验结果表明“猎鹰”具有较低的能耗和较高的服务质量。猎鹰在多个边缘云之间保持不变的联盟链。最后，实验结果表明“猎鹰”具有较低的能耗和较高的服务质量。猎鹰在多个边缘云之间保持不变的联盟链。最后，实验结果表明“猎鹰”具有较低的能耗和较高的服务质量。
