Resource Allocation in C-V2X and DSRC Technologies: Analysis and Simulation-based Evaluation for V2V Direct Vehicular Communication

Abstract:

This article focuses on the analysis and evaluation of the 802.11p, LTE-V2X mode 4, and NR-V2X mode 2 technologies. The addressed problem is the need to assess the performance of these technologies in meeting the requirements of advanced V2X applications. A review of these technologies and radio resource allocation is performed. Subsequently, simulations are conducted to verify the performance of the technologies, specifically in terms of Packet Delivery Ratio (PDR) based on distance, in order to determine the coverage range for reliable transmission. The results show that 802.11p technology is more susceptible to variations in traffic density and an increase in the number of packets per second, whereas C-V2X technologies such as LTE-V2X and NR-V2X demonstrate better performance in various test scenarios involving changes in packet frequency and vehicular density. In conclusion, it is essential to consider performance, latency, and coverage range to meet the requirements of advanced V2X communication applications.
