Radio access technologies, such as Cellular vehicleto-everything (C-V2X) and dedicated short range communications (DSRC), have been used to support robust communication in connected vehicles’ scenarios. However, existing studies mostly dealt with homogenous vehicular networks, where coexistence of different radio access technologies in vehicles are not considered. More precisely, such multi radio interface environments burden communications among vehicles. In this paper, we first review DSRC and C-V2X radio access technologies and existing packet relaying mechanisms that are specifically designed for homogenous or heterogeneous vehicular environments. We then present quality of service aware relaying algorithm (QR) that incorporates multi metric to prioritize dual interface vehicles (DVs) and provide robust communications among vehicles that are equipped with different radio access technologies. The simulation results confirm the superiority of the proposed QR in terms of message reception and relaying count as compared to the standard protocols.
