A method includes joining a vehicular access network (VAN) comprising cooperative communication between a plurality of on-board units (OBU) in respective vehicles, scanning the VAN to pick up a coverage of at least one infrastructure access point (IAP), which operates on a control channel in a radio access tree (RAT) comprising a plurality of cells, listening to a channel allocation information from the IAP that includes a request for a mobile cell gateway (MCG) at a nominal location in the RAT, and sending a candidacy message to the at least one IAP to become an MCG. Certain embodiments include establishing the VAN in a highway, and in urban areas, aggregating traffic in a cell and transmitting to the IAP via the MCG, and other features.
