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.

1. A method comprising: joining a vehicular access network (VAN) in a location, the VAN facilitating communication between a plurality of on-board units (OBU) in respective vehicles;scanning the VAN for coverage of at least one infrastructure access point (IAP), wherein the at least one IAP operates on a control channel in a radio access tree (RAT) comprising a plurality of cells;receiving channel allocation information from the at least one IAP, wherein the channel allocation information comprises at least one request for a mobile cell gateway (MCG) at a nominal location in the RAT; andsending a candidacy message to the at least one IAP to become an MCG. 2. The method of claim 1, further comprising: performing functions of the at least one IAP and establishing the control channel in the RAT if the coverage cannot be identified. 3. The method of claim 1, wherein at least one OBU in the plurality of OBUs is mobile. 4. The method of claim 1, wherein the at least one IAP is a roadside unit (RSU) operating on at least one short-range wireless channel. 5. The method of claim 4, wherein at least two cells in the plurality of cells overlap with each other. 6. The method of claim 1, wherein the nominal location is at an edge between two cells in the plurality of cells. 7. The method of claim 1, wherein the plurality of cells are covered by at least two non-overlapping channels. 8. The method of claim 1, further comprising: locating in a first cell in the plurality of cells, a first MCG that aggregates a first traffic from at least one node in the first cell;locating the IAP in a second cell; andtransmitting the first traffic to the IAP. 9. The method of claim 8, further comprising: locating in a third cell a second MCG that aggregates a second traffic from at least one node in the third cell;transmitting the first traffic to the second MCG; andtransmitting the first traffic and the second traffic to the IAP. 10. The method of claim 8, further comprising: locating a vehicular mobile router (VMR) in the first cell that aggregates end-node traffic from end nodes; andtransmitting the end-node traffic to the first MCG. 11. The method of claim 10, wherein the VMR is an OBU in the plurality of OBUs and performs functions of a femtocell. 12. The method of claim 1, wherein the location is a highway. 13.
