Blockchain for Smart Vehicular Communications

Abstract

Blockchain’s appeal is expanding as additional application industries seek to profit from its immutability, security, costsavings, transparency, and processing speed. Blockchain has helped many industries improve their existing systems or complete system design shifts. For example, blockchain has enabled IoT systems to improve service quality while meeting security requirements. This technique is generating much academic interest in other domains, such as the Internet of Vehicles (IoVs). The study classifies blockchain-enabled systems generically as vehicular ad hoc networks (VANETs). The distributed ledger technology (DLT) paradigm has transformed VANET communication paradigms and practices. The study will also look for open concerns related to blockchain for opportunities. The concept of Internet of Vehicles (IoV) embraces the potential of blockchain technology to enhance security in electric vehicle (EV) transactions, enabling decentralized, transparent, and secure electricity trading. Moreover, the utilization of blockchain technology holds the promise of substantially improving energy efficiency, reducing management expenses, and ensuring the optimal utilization of energy resources. As a result, its implementation in the IoV idea enables EVs to trade energy in a secure, autonomous, and automatic manner. The purpose is to investigate existing IoV difficulties and demonstrate how blockchain properties might aid this new paradigm. The limitations and potential research paths of blockchain technology integration within the IoV are also emphasized. Systems for vehicle networks need to handle data storage effectively and ensure secure transactions and interference-free networks. The immutability and tamperproof nature of blockchain make it a promising alternative for 5G car network systems. Additionally, inherent security assessments have been conducted, uncovering various difficulties and challenges associated with implementing blockchain technology in 5G vehicular networks.
