Towards Multi-Access Edge based Vehicular Fog Computing Architecture

In this paper, we propose a multi-access edge based vehicular fog architecture. It is based on the integration of fog computing (FC) and multi-access edge computing (MEC) with the vehicular cloud. The aim of this architecture is the exploitation of unused vehicular resources and infrastructure equipment to bring the cloud at the proximity of users. The vehicular cloud serves as fog nodes that receive and process the users' requests. The control of the vehicular cloud and further processing are ensured by a MEC server. We describe the modules of the proposed architecture and the interaction between them in both cases static and mobile vehicular cloud. In order to optimize the access to the MEC server and to the conventional cloud, we suggest a fuzzy-based gateways' selection approach. It allows the selection of a set of vehicles that act as relays between the fog nodes (i.e. vehicles) and the cloud.
