Modern vehicular communication systems are facing significant challenges since the rapid development of intelligent transportation systems and the ever-growing vehicular applications have activated intense information exchange among vehicles, infrastructures, and pedestrians. Without the support of powerful communication, many vehicular services will just stay in conceptual phase and cannot be put into practice. To provide low-latency services to vehicles on roads, vehicular fog computing (VFC) is recently introduced as a promising solution, which utilizes enormous vehicles on roads as communication and computation resources and extends cloud computing service to an edge network. On the other hand, the publish/subscribe (pub/sub) paradigm provides a loosely coupled and scalable communication which can facilitate flexible and dynamic vehicular network services. Motivated by the merits of these two research fields, in this paper, we propose a novel joint design of pub/sub communication model based on VFC architecture, which employs fog nodes as the data platform for messages aggregation. Specifically, we describe a method to measure vehicle mobility and construct a stable VFC on roads. Then, a message dissemination approach is designed based on our communication model. Finally, the experimental results confirm the efficiency of our proposed model in various urban scenarios.
