Socially-Aware V2X QoS for NOMA Dual-Connectivity

Vehicle-to-everything (V2X) is one of the core technologies associated with 5G. It enables vehicles to communicate with other vehicles, networks, and infrastructure. Despite the promise V2X offers, i.e. ubiquitous vehicular connectivity, an often overlooked aspect of V2X is the impact bursty data, such as that encountered when a vehicle accident occurs, has on the network's Quality of Service (QoS). In this work, we study both 4G V2X and 5G V2X utilizing Evolved Universal Terrestrial Radio Access New Radio (E-UTRA-NR) Dual Connectivity (en-DC) Road Side Units (RSUs). By using social groups to determine QoS, versus statically defining QoS, we find that we can leverage 5G RSUs to minimize the impact of localized bursty traffic events on the overall network's QoS, while at the same time enabling regional awareness of localized road traffic conditions via a socially-aware Road Condition Warning Systems (RCWS). We demonstrate that our proposed socially-aware QoS management methodology outperforms legacy socially-unaware 4G V2X and can prove beneficial for 5G V2X and beyond.
