Internet of Vehicles: Architecture, Protocols, and Security

TLDR

The growing connectivity of vehicles to the Internet of Things drives the need for seamless, secure, robust, and scalable information exchange among vehicles, humans, and roadside infrastructure, prompting the evolution of vehicular ad‑hoc networks into the Internet of Vehicles (IoV). This paper outlines the benefits of IoV, reviews recent industry standards that facilitate its adoption, and identifies future research directions that the vehicular community should pursue. We present recently proposed communication protocols designed to enable seamless integration and operation within the IoV ecosystem.

Abstract

Today, vehicles are increasingly being connected to the Internet of Things which enable them to provide ubiquitous access to information to drivers and passengers while on the move. However, as the number of connected vehicles keeps increasing, new requirements (such as seamless, secure, robust, scalable information exchange among vehicles, humans, and roadside infrastructures) of vehicular networks are emerging. In this context, the original concept of vehicular ad-hoc networks is being transformed into a new concept called the Internet of Vehicles (IoV). We discuss the benefits of IoV along with recent industry standards developed to promote its implementation. We further present recently proposed communication protocols to enable the seamless integration and operation of the IoV. Finally, we present future research directions of IoV that require further consideration from the vehicular research community.
