This work focuses on the evolution of connected vehicles communication technologies and performance evaluation of vehicular communication systems, specifically in the context of Cellular Vehicle-to-Everything (C-V2X) technology and the Third Generation Partnership Project (3GPP) specifications. The dissertation also discusses the evolution of vehicle communication systems from Dedicated Short-Range Communication (DSRC) through 5G technologies. It examines the motivation for this shift, which are the growing demand for transportation safety, low latency, high data rate, low energy use, and seamless inter connectivity. The research delves into the greater capabilities and improved performance that 5G offers for direct V2V communications by analyzing the gains made by 5G technology, particularly the introduction of the C-V2X radio access technology and the sidelink PC5 interface. The research intends to investigate the challenges in direct vehicle-to-vehicle (V2V) connections using the sidelink PC5 interface for resource allocation optimization and communication reliability. Thus, this study investigates the effects of several parameters, including vehicle density, speeds, and distance settings, on the performance of direct V2V communications. The findings enable the creation of effective and dependable communication systems for congested and interference-prone situations, as well as the improvement of resource allocation algorithms. The research's ultimate goal is to increase the security, dependability, and efficacy of vehicular communication systems, supporting the development of safer and more effective transportation networks for the next generation of Intelligent Transportation Systems (ITS) in the connected and autonomous vehicles' era.
