Modeling and Performance Analysis of mmWave and WiFi Transmissions for V2V Communications

Abstract

Vehicle-to-Vehicle (V2V) communications are revolutionizing the connectivity of transportation systems, ensuring safe and efficient road mobility. To meet the growing bandwidth needs of V2V services, the use of millimeter-wave (mmWave) and WiFi frequency bands has been proposed as a promising solution. However, communications at these frequencies are a challenging task due to the severe path-loss especially in a high-blocked environment. In this paper, we present a comparative study between mmWave and WiFi communication systems. In particular, realistic stochastic geometry tools have been used to accurately model and describe a typical V2V communication systems, where vehicles are randomly located. Accordingly, we derive the corresponding Successful Transmission Probability (STP) and Average Throughput (AT) expressions for both communication systems. In addition, Monte Carlo simulations have been performed and presented to confirm the analytical results, and to investigate the advantages and disadvantages of the mmWaves and WiFi systems, in different scenarios.
