Abstract
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.
Highlights
With the rapid development of mobile Internet and Internet of ings technologies, various new services have been continuously emerging, making mobile communication traffic experience explosive growth in the past few years
Make the following changes: (1) Modification of the checkpoint protocol: this paper clears the certificate based on the timestamp of the best block in the blockchain. e improvement we propose is to clear the block from the timestamp of the best block in the blockchain. e blockchain is connected in the form of a linked list according to the generation time of the block, so a certificate before a block timestamp has been verified, and the relevant status of the node has been broadcast and can be cleared
Falcon uses blockchain technology in an edge cloud environment that lacks centralized management of different heterogeneous hardware, which can make the migration of edge services in a dynamic, open, and collaborative mobile edge computing (MEC) network environment more secure and reliable. e Falcon framework we proposed is safer in the absence of a trusted third-party environment and is more suitable for practical applications
Summary
With the rapid development of mobile Internet and Internet of ings technologies, various new services have been continuously emerging, making mobile communication traffic experience explosive growth in the past few years. The VM overlay is not easy to maintain which limits the application in industry and academia These studies did not consider the migration trust of edge services in different edge clouds. Falcon uses a more flexible and portable mobile agent as the carrier of edge services and uses blockchain technology to jointly maintain a trusted alliance chain to solve the trust problem of service migration in multiple edge clouds. Seek the migration strategy with the greatest benefit through the migration decision algorithm and guarantee higher user service quality We deployed this framework in a computing cluster to evaluate its performance.
