A reference framework for social-enhanced Vehicle-to-Everything communications in 5G scenarios

In this paper we speculate on how the social dimension can be leveraged in future fifth generation (5G) V2X systems. Specifically, we propose a novel social-enhanced 5G-V2X framework which leverages mobile edge computing (MEC) and software-defined networking (SDN) technologies with the aim to exploit social relationships between V2X entities and facilitate data delivery in this context. Early results are provided to showcase the viability of the proposal in a representative scenario, i.e., safety alert dissemination, and demonstrate its benefits compared to a legacy cellular-aided data dissemination approach.
