Abstract
Next-generation vehicle-to-everything (V2X) networks are envisioned as communication platforms, which not only aim to improve road safety and drastically increase traffic efficiency but also introduce a plethora of innovative applications that mostly require ultrareliable low-latency communications. Motivated by such new applications and its accompanying services, future vehicular networks can easily switch from current connected vehicles, mostly vehicle-to-vehicle, to fully heterogeneous V2X networks that support autonomous driving. Toward this target, the deep integration between artificial intelligence (AI) and fog computing (FC) technologies within the future V2X networks is a step whose time has come. In this survey, we address a novel and practical AI-enabled vehicular network architecture with FC in its core. Moreover, we present AI-enabled, fog-assisted V2X use cases that accommodate important FC capabilities and exploit the power of AI for enabling the desired evolution of vehicular networks. Finally, some potential issues of AI in FC-based V2X networks for future work are discussed.
