Vehicle-to-everything (V2X) communication is the next innovative technology to transform the automotive industry. It implements the power of Internet of things (IoTs) connectivity and processing to improve the efficiency, performance, and safety of future vehicles. V2X enables vehicles to have a high awareness of the surrounding environmental factors, infrastructures, and other vehicles through the advanced sensing and communication technologies in place. Current communication platforms in place are not able to fully support the transmission of high priority safety critical data required to provide these services. Individually, the two main V2X architectures (DSRC and C-V2X) have limitations which inhibit them from fully supporting the V2X platform. As such, this chapter proposes the integration of 5G technology, which supports all types of communication technologies through the integration of reconfigurable devices and offers higher data rates and bandwidths than any preceding platform. The architecture proposed in the chapter is composed of three layers: DSR V2X for direct short-range communication; cellular V2X layer which will combine 5G cellular platform to provide backup communication when DSR V2X layer fails and multimedia capabilities; and satellite (SAT)-V2X which provides extra backhaul connectivity when both DSR and cellular V2X is unavailable. The system design, modeling, and simulation results yield a more reliable and sustainable V2X capacity for critical real-time vehicular communication applications.
