Research of the Performance of Software-Defined Infrastructure in VANET Networks Based on Models of Hybrid Data Transmission Devices

The development of new generation networks based on software-defied networks and their inclusion in the 5G stack requires new approaches to studying the operation of such networks. Most researchers trust frameworks for all low-level work, focusing on higher-level metrics. However, most simulation tools have a very limited ability to study software-defied hardware, especially packet latency. There is also insufficient attention paid to the models of virtual network devices, which behave differently from physical hardware and have different performance parameters and dependencies on external factors. All this led to the writing of this article, the purpose of which is to study the internal structure of the network equipment of the OmNET ++ modeling system, as well as create alternative models that take into account all the features of various software-defined equipment implementations. As a result of the study of the created models, an improvement in the simulation accuracy in terms of packet processing delay parameters is shown compared to the traditionally used building blocks of network equipment models
