Emerging Technologies for V2X Communication and Vehicular Edge Computing in the 6G era: Challenges and Opportunities for Sustainable IoV

This paper presents a comprehensive review of emerging technologies in V2X communication and Vehicular Edge Computing (VEC) for sustainable Internet of Vehicles (IoV) in the 6G era. The paper employs the PRISMA method to systematically identify, screen, select, synthesize, and report relevant literature. The objective is to identify and discuss key technologies, assess challenges and opportunities, analyze potential impacts on energy efficiency and environmental sustainability, and provide recommendations for future research directions. Challenges analysed include both technical and non-technical challenges and oppportunities include both societal benefits as well as industry opportunities. Finally and based on these findings, future research directions are proposed for striving towards sustainable IoV.
