Abstract

The invention relates to a device for either generating or maintaining an organic data network having an dynamic topology, comprising

• • a data processing unit,
  • at least one data connection to a data network to which several devices provided with a data processing unit are connected by means of a data connection, and
  • software having
    • a receiving routine for receiving data packages of at least one transmitting device in the data network,
    • a transmission routine for transmitting data packages, received from the transmitting device or devices in the data network to at least one receiving device that is connected to the data network, independent of the transmitting device or devices.

Additionally the invention relates to a method and software for data packages received from a transmitting device to at least one receiving device, independent of said transmitting device.

A device according to the invention can be used in for instance mobile phones, streaming internet applications and cable television.

Claims

1. A method for distributing data, using wireless peer to peer (P2P) connections between motor vehicles, comprising:

issuing a first request for data from a first device of a first motor vehicle to at least a second device of a second motor vehicle, the first device being wirelessly coupled to the second device,

in response to a the first request, transmitting at least a part of the data requested in the first request from the second device of the second motor vehicle to the first device of the first motor vehicle; and

in response to the receipt of a second request from a third device of a third motor vehicle, transmitting at least a portion of the data transmitted in response to the first request, from the first device of the first motor vehicle to the third device of the third motor vehicle, the third device being wirelessly coupled to the first device.

2. The method according to claim 1, wherein the response to the first request and the response to the second request comprise traffic information.

3. The method according to claim 1, wherein the response to the second request comprises information about at least the second motor vehicle.

4. The method of claim 1, wherein the first device of the first motor vehicle is configured to issue the first request autonomously.

5. A method of distributing data using connections in a network, the network including one or more production nodes that send data, and a plurality of consumer nodes, wherein each consumer node receives data from one or more production nodes or at least one other consumer node and is operationally coupled to a motor vehicle, the method comprising:

(a) providing a plurality of consumer nodes, wherein each given consumer node is configured to;

(i) issue a first request for data to at least one production node or at least another consumer node that is directly connected to the given consumer node; and

(ii) in response to a request for data issued by one other consumer node, transmit data from the given consumer node to the one other consumer node;

(b) providing one or more production nodes configured to transmit data to a requesting consumer node in response to a request for data issued by the requesting consumer node;

(c) in response to receipt of the first request from the given consumer node by the at least one consumer node or the at least one production node;

(i) if the node receiving the first request is a consumer node, transmitting at least a portion of the requested data to the given consumer node; and

(ii) if the node receiving the first request is a production node, transmitting at least a portion of the requested data to the given consumer node;

(d) after step (c), and independent of said first request, issuing a second request for data from a second consumer node, the second request issued to the given consumer node; and

(e) in response to receipt of the second request, transmitting to the second consumer node at least a portion of the data requested by the second request.

6. The method of claim 5, wherein the data comprises at least traffic information.

7. A method of distributing data, using wireless peer to peer (P2P) connections between a plurality of devices, each device operationally coupled to a motor vehicle, the method comprising:

(a) issuing a first request for data from a first device of a first motor vehicle to a second device of a second motor vehicle, the first device being wirelessly coupled to the second device;

(b) in response to the receipt of the first request by the second device, transmitting at least a portion of the requested data to the first device;

(c) after step (b), and independent of said first request, issuing, from a third device of a third motor vehicle, a second request to the first device for at least a part of the portion of the requested data; and

(d) in response to receipt of the second request, transmitting to the third device at least a portion of the data requested by the second request.

8. The method according to claim 7, wherein the first device and the second device are part of a traffic information system.

9. The method according to claim 7, wherein the first device and the second device are part of a route navigation system.

10. The method according to claim 9, wherein the route navigation system is provided with GPS.

11. The method according to claim 7, wherein said the first device is a radio.

12. The method according to claim 7, wherein the first device is part of a radar system.

13. The method according to claim 7, wherein the first and second devices are part of a motor vehicle information system.

14. The method according to claim 7, wherein said data comprises traffic information.

15. The method according to claim 7, wherein said data comprises information about said at least one other motor vehicle.
