An Intelligent Transaction Migration Scheme for RAFT-based Private Blockchain in Internet of Things Applications
This addresses latency issues for IoT applications using blockchain in edge computing, but it is incremental as it builds on existing RAFT and MEC frameworks.
The paper tackles the challenge of high latency in storing data on a RAFT-based private blockchain for IoT applications, especially during anomaly-triggered data flows, by proposing an intelligent transaction migration scheme that moves transactions from busy to idle areas, resulting in reduced latency in high data flow circumstances.
The integration of multi-access edge computing (MEC) and RAFT consensus makes it feasible to deploy blockchain on trustful base stations and gateways to provide efficient and tamper-proof edge data services for Internet of Things (IoT) applications. However, reducing the latency of storing data on blockchain remains a challenge, especially when an anomalytriggered data flow in a certain area exceeds the block generation speed. This letter proposes an intelligent transaction migration scheme for RAFT-based private blockchain in IoT applications to migrate transactions in busy areas to idle regions intelligently. Simulation results show that the proposed scheme can apparently reduce the latency in high data flow circumstances.
