Block Data Components' Effect on the Efficiency of a Blockchain-based VANET Using Hyperledger Fabric

PROJECT TITLE :

Impact of Block Data Components on the Performance of Blockchain-based VANET Implemented on Hyperledger Fabric

ABSTRACT:

The way in which we share, manage, and trade our data has shifted from a centralized to a decentralized architecture as a direct result of Blockchain technology, which is an important innovation in the modern era. In response to the growing demand for Blockchain technology, a variety of platforms have been developed to enable the implementation of public, private, consortium, permissioned, or permissionless Blockchain. Linux served as the hosting platform for Hyperledger, which is a permissioned, open-source, distributed ledger-based Blockchain. The Hyperledger Fabric Private Blockchain Network is investigated throughout this paper (HFPBN). The architecture of HFPBN, including all of its parts and the flow of transactions, is investigated in great detail. The Blockchain used by HFPBN is made up of multiple blocks, all of which are connected to one another. After an in-depth discussion of the block's constituent parts, including their types and dimensions, the total size of the block, which is contingent on a number of different parameters, is then determined. In addition, a case study of one application of Blockchain technology known as Vehicular Ad-hoc Networks (VANETs) is presented and discussed in this article. The Hyperledger Fabric platform is utilized in the implementation of the VANET application. For the VANET system, formulas are derived to show the dependency of various parameters, such as endorsement policy, number of transactions, and number of reads and writes, on block size. These formulas are then shown in their relationship with one another through a graph. Then, utilizing Hyperledger Caliper, an analysis of the impact of block size on a variety of performance parameters, such as throughput, latency, memory, and CPU utilization, for the VANET system is carried out. A Blockchain-based VANET has reached its goal of achieving an optimal required value of both throughput and latency. Additionally, the Hyperledger Fabric platform appears to be appropriate for a variety of applications due to the fact that it generates a distinct Blockchain for each application.
