Blockchain‐based internet of vehicles ( BIoV ): A systematic review of surveys and reviews

Abstract

The Internet of vehicles (IoV) has appeared as an effective method of obtaining an intelligent transportation system able to deliver various innovative solutions and enable several applications as a replacement for vehicular ad‐hoc networks (VANETs). To help IoV contexts, enormous quantities of information are created and transmitted between various communication components wirelessly across multiple channels, which may entice attackers and put the network at risk. Security is one of the vital concerns and critical issues in VANETs and IoV networks. Blockchain is employed to create a distributed and secure IoV to overcome some centralized concerns and enhance the network architecture. This article presents a systematic and detailed review by selecting 28 review articles from 2018 to 2022 on blockchain‐based IoV (BIoV). We investigate the latest review and survey articles regarding their aspects, contributions, findings, limitations, and strong points to address unsolved problems of BIoV. In this article, the review/survey articles are systematically reviewed to resolve taxonomy aspects intended for BIoV. We provide a new taxonomy and discuss security concerns, open issues, and future directions so that researchers in this field can quickly and easily access recent content and do not need to read numerous review articles.
