5G NR-V2X Mode 2 Simulation

This work studies the performance and efficiency of sidelink communication in self-organizing vehicular networks using ns-3 and MoRe-V2X simulation software packages. The evaluation is based on various criteria, including message delivery success, collision loss rate, signal attenuation rate, average peak age of information, and average age of information. The main purpose and novelty of this work is to study how the persistence parameter, a probabilistic indicator for the redistribution of radio resources, affects semi-persistent scheduling (hereinafter referred to as SPS) at the media access control level in the network. This dependence has not yet been studied. The SPS algorithm is a standard method for allocating resources in a machine-to-everything communication system, providing users with "free" and immediate uplink access. This reduces scheduling frequency and system complexity by assigning users the same wireless channels without having to consume wireless resources and wait for scheduling decisions. The purpose of the study is to study key performance indicators in conditions of asynchronous traffic when messages from different network nodes are generated at different speeds. The results of this study provide valuable information on the dependence of key performance metrics of self-organizing 5G NR V2X vehicular networks under aperiodic traffic conditions on the probability of persistence, as well as the number of vehicles. An important feature is the study of the influence of the above-described quantities on the age of information.
