This paper explores the role of wireless network technologies in enhancing the efficiency, safety, and traffic management of smart cities. The primary goal is to ensure that smart cities operate with the utmost efficiency and minimal transportation congestion, even in the presence of self-driving cars, which currently exhibit instability and susceptibility to errors. Existing research gaps in the domain of Vehicular Ad-Hoc Networks and Vehicle-to-Everything studies revolve around concerns related to privacy and security, signal interference, message propagation, and mobility management. To address these gaps, our project conducts a comprehensive investigation using wireless sensor networks, vehicle-to-vehicle networks, and vehicle-to-infrastructure networks. This study sheds light on issues pertaining to privacy and security, signal interference, the dynamics of message propagation, and challenges related to mobility management that currently impede V2X-based systems from realizing their full potential. By seamlessly integrating state-of-the-art wireless technology, notably Visible Light Communication, this framework aims to mitigate traffic congestion, minimize accidents, and streamline traffic-related operations. VLC technology plays a crucial role in facilitating communication between vehicles and infrastructure, enabling real-time data transmission and enhancing traffic management, accident prevention, and congestion alleviation. The paper serves as a roadmap for the development of smarter, safer, and more resilient smart cities, set to revolutionize urban mobility through the utilization of cutting-edge wireless technology, particularly VLC technology.
