Comparison and Optimization of DSRC and C-V2X Technologies: Current Status, Challenges, and Future Prospects

DSRC (Dedicated Short-Range Communication) and C-V2X (Cellular Vehicle-to-Everything) have emerged as two key communication technologies for vehicular networks. However, both technologies face challenges in terms of communication performance and integration. This paper presents a detailed comparison and optimization study of DSRC and C-V2X, focusing on their status, technical challenges, and future development trends. The study reviews recent advancements in enhancing the throughput, communication range, and resource allocation of both technologies. Moreover, we explore the potential of AI and 5G technologies in addressing the limitations of DSRC and C-V2X, offering insights into their integration in next-generation vehicular communication systems. Finally, this paper discusses the technical challenges and possible future directions for the convergence of these two technologies, aiming to enhance vehicular network efficiency and support advanced V2X applications.
