Strategy for dynamic blockchain construction and transmission in novel edge computing networks

Abstract

The distributed transmission of a dynamic blockchain in a cloud computing platform may cause network overload. To overcome this challenge, a novel idea for a network architecture that is suitable for blockchain transmission and storage is proposed. Emerging edge computing technology has been proven to improve the efficiency of blockchain construction and operation. In this paper, we focus on solving the problem of unbalanced resource allocation for blockchain construction and transmission in a novel edge computing network architecture. We propose the edge bandwidth and storage optimization (EBSO) algorithm to balance effective bandwidth allocation and storage space selection during dynamic blockchain processing. In addition, we build a dynamic blockchain based on a link bandwidth allocation analysis in an edge computing network environment. Subsequently, the reasonable value range of the tradeoff parameter γ between the link bandwidth and storage space during the transmission of the constructed dynamic blockchain is determined. Finally, we use version 2 of the network simulator (ns-2) to simulate the performance of the EBSO algorithm and compare it with other excellent algorithms in terms of transmission bandwidth efficiency (TBE), storage space efficiency (SSE), blockchain construction efficiency (BCE), average throughput, and average delay in the same network environment.
