Till nowadays, V2X communication has been based primarily based on ETSI ITS-G5 using the IEEE 802.11p standard for dedicated, short-range, ad-hoc vehicular communication. It basically means that the data exchange between vehicle On-board Units (OBUs) and Road-side Units (RSUs) deployed in the road infrastructure is performed through direct Wi-Fi-like communication. However, trends show that this is set to change. Cellular V2X (C-V2X) standards (today 4G LTE/LTE-A, later 5G) are emerging for the new line of V2X communications. In the near future it will be possible to involve the widest scale of road users (e.g. not only vehicles but also pedestrians, cyclists, etc.) in the cooperative  processes of intelligent transport systems (ITS) in the form of C-V2X communication between devices. The task of the student is to study the existing "artery" V2X simulation  framework implemented in OMNeT++ (https://github.com/riebl/artery), then desing, implement and evaluate hybrid V2X scenarios where different V2X access technologies are available for integrating more systems, different road users, and services into the V2X ecosystem. Required programming skill: C++, Git.
