Abstract

One of the promising techniques used to allow Intelligent Transportation System (ITS) is to make vehicles communicate with each other without the need for base station infrastructure. This will enhance the reliability of the network and makes transferring data from one vehicle to another more easy and fast. Autonomous communication faces some challenges which are the resources management process between vehicles, the data rate of the communication link, and the latency of a centralized controlling network. Cellular Vehicle-to-Everything (C-V2x) communication is a promising technology to overcome these challenges due to several advantages that it gives. It uses cellular communication which provides a high data rate compared to the IEEE 802.11p network when using mmwave bands. It allows using distributed management of resources which allows decreasing latency of the communication and enhancing the self-management process of the available resources. In this paper, the use of the C-V2x mode 4 links between vehicles traveling at middle speed in an urban scenario is used and evaluated concerning Packet Delivery Ratio (PDR). Simulation is performed concerning the distance between vehicles, the frequency band used, the error probability of the communication concerning all error types, and the density of vehicles on the proposed road. Simulation results show that the PDR decreases as the frequency increase because of the need for short-range communication and also show that the error probability increases as the density of vehicles increases.
