  The development of intelligent transportation systems raises many
requirements to the current vehicular networks. For instance, to ensure secure
communications between vehicles, low latency, high connectivity and high data
rate are required for vehicular networks. To meet such requirements, the 5G
communication systems for vehicular networks should be improved accordingly.
This article proposes a communication scheme for 5G vehicular networks, in
which moving access points are deployed on vehicles to facilitate the access of
vehicle users. Moreover, the adjacent vehicle-installed moving access points
may cooperatively communicate with the vehicle users by joint transmissions and
receptions. In this way, the vehicle users communicate with one or more
unspecified cooperative access points in a cell-less manner instead of being
associated to a single access point. To manage such cell-less networks, local
moving software-defined cloudlets are adopted to perform transmission and
scheduling management. Simulation results show that the proposed scheme
significantly reduces the latency, while improving the connectivity of the
vehicular networks, and can be considered as a research direction for the
solution to 5G vehicular networks.
