Internet of Vehicle (IoV) Applications in Expediting the Implementation of Smart Highway of Autonomous Vehicle: A Survey

Abstract

As the main pillar of the Smart City, Smart Highway manifests the centralized connectivity concept between the self-driving vehicles. Internet of Vehicle (IoV) is identified as the solution for an improved connectivity between the driverless vehicles. IoV allows the vehicle to share data in the form of sensory data, risk data, environmental perception data as well as localization data, among many others. In addition, IoV can facilitate the interaction of the vehicles with the environment, pedestrians as well as other vehicles sensory information through the means of vehicle-to-x (V2X). This can aid the autonomous vehicle in preventing unwanted collisions, improving its localization aspects as well as its other modules, such as path planning and motion guidance. The use of IoV can also yield a better in-vehicle entertainment experience during the long journeys. In addition, the incorporation of the IoV can help in reducing the traffic jam by allowing the traffic information to be obtained by the vehicle instantaneously, prompting a new path replanning action by the AV. However, most of the works still suggest an early stage of IoV development. Thus, not many surveys have been performed to study the current progress of IoV application. In this work, the authors write the overview of IoV, e.g. its emergence history, its importance to the vehicle connectivity as well as the current application of IoV in the autonomous vehicle. In addition, several issues of the IoV which involve connectivity between the environment, the requirement of wide coverage of 5G Internet as well as security concerns are concisely highlighted. To verify the importance of IoV, a case study via the means of computational simulation is done by integrating the collision avoidance system of the AV with IoV. Several future work opportunities and research ideas in the IoV field are enlisted for a comprehensive AV navigation in the smart cities’ highway. This work is beneficial to give an overview of the IoV applications in expediting the development of a Smart Highway for driverless vehicles. As this work is intended as a general survey of IoV aimed for the reading of researchers and industrialists from the multi-field background, the detailed technical specifications of the IoV are hence omitted.
