Hierarchical floating car data network
First Claim
1. A vehicle data network comprising:
- a central server that transmits signals;
an egress point network, comprising a plurality of egress points, in communication with said central server wherein the plurality of egress points include fixed egress points and mobile egress points and further, wherein the plurality of egress points each receives the signals transmitted by the central server, anda participating vehicle network, comprising a plurality of participating vehicles, in communication with the egress point network and wherein the plurality of participating vehicles are in direct communication with each other for vehicle-to-vehicle communications and each mobile egress point in the egress point network corresponds to a participating vehicle in the participating vehicle network, wherein at least one of other participating vehicles communicating in vehicle-to-vehicle communication communicates with a mobile egress point in the egress point network, and wherein, the at least one of the other participating vehicles comprises a vehicle other than the mobile egress points, andwherein the at least one of the other plurality of vehicles participating in the vehicle network that is communicating in vehicle-to-vehicle communication communicating with the mobile egress point in the egress point network is in communication with the central server through the participating vehicle network and further, wherein when the at least one of the other participating vehicles is not able to receive signals from the central server, the at least one of the other participating vehicles receives information using vehicle-to-vehicle communication from the at least one of the participating vehicles that is a mobile egress point.

Abstract
A hierarchical floating car data network comprises a central server, an egress point network, and a participating vehicle network. The egress point network is in communication with the central server. The egress point network comprises a plurality of egress points. The participating vehicle network comprises a plurality of participating vehicles. At least some of the plurality of participating vehicles are in direct communication with each other. At least some of the plurality of participating vehicles are in communication with at least some of the plurality of egress points. Furthermore, at least some of the plurality of participating vehicles may be in communication with the central server. A geographic database is formed from content communicated between the elements of the hierarchical floating car data network.

19. A vehicle data network method comprising the steps of:
-
(a) transmitting content from a participating vehicle network comprising a plurality of participating vehicles to an egress point network comprising a plurality of egress points wherein the egress points include fixed egress points and mobile egress points, wherein the plurality of egress points each receives signals transmitted by a central server, wherein the plurality of participating vehicles are in direct communication with each other for vehicle-to-vehicle communications and each mobile egress point corresponds to a participating vehicle in the participating vehicle network, wherein at least one of other plurality of participating vehicles communicating in the vehicle-to-vehicle communication communicates with a mobile egress point in the egress point network, wherein, the at least one of the other participating vehicles comprises a vehicle other than the mobile egress points, and further, wherein the content comprises signals that include location based information; (b) accumulating content at the plurality of egress points; (c) transmitting the accumulated content at the plurality of egress points to a central server; and (d) at the central server, performing calculations on the accumulated content and wherein the at least one of the other plurality of participating vehicles that is communicating in vehicle-to-vehicle communication communicating with the mobile egress point is in communication with the central server through the participating vehicle network and further, wherein when the at least one of the other participating vehicles is not able to receive signals from the central server, the at least one of the other participating vehicles receives information using vehicle-to-vehicle communication from the at least one of the participating vehicles that is a mobile egress point. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
