An Intelligent Transaction Migration Scheme for RAFT-based Private Blockchain in Internet of Things Applications
Abstract : 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 anomaly-triggered 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.
? The consensus algorithm is used to achieve consensus between nodes for alteration or modification of existing ledgers, only to append them into a new block at the end of the chain within the Blockchain.
? But this method of distributed network would be efficient in converting existing webs to be decentralized and allow legacy centralized networks to exists in a decentralized manner.
? There are no existing communication standards for IoT between different types of smart devices.
? CCN is able to improve the existing method of routing and forwarding from TCP/IP due to the named data.
? A few works focus on addressing issues in blockchain network with RAFT consensus.
? To the best of our knowledge, none of the literature has addressed the issue of how to reduce latency for IoT applications in RAFT-based private blockchain network .
? This includes the need for minimal cost hardware implementation, minimal power usage, and minimal latency. In response to these problems, lightweight cryptographic primitives have been proposed in this model.
? To address this problem, we propose that peer networks can elect other nodes as their blockchain server.
• With the current trend of pursuing the decentralized Internet, many methods have been proposed to achieve decentralization considering different aspects of the current Internet model ranging from infrastructure and protocols to services and applications.
• While there are several current works proposed to adapt and apply Blockchain based architecture for IoT, and interconnected devices on edge networks, there is a considerable lack of research to propose and apply Blockchain for the core networks of Internet and its protocols, applications and services.
• Some decentralization approaches have already proposed in current literature to resolve Internet flaws originated from centralization.
? The random scheme provides the average performance for all the possible schemes since each action of this scheme can be selected with equal probability after training enough times.
? It proves that static schemes cannot help improve the performance, even if they can migrate transactions from busy areas.
? There are quite a few consensus algorithms available for blockchain that support high throughput; however, they require extremely high-performance for the network.
? The framework describes the implementation, design and performance of Hyperledger Fabric blockchain for smart hospitals.
? Raft based consensus algorithms have high throughput but low network scalability, and therefore, it has extremely high-performance requirements for the network.
