Abstract

Embodiments of cooperative communication of data are presented herein.

Claims

1. A method implemented by a source device, the method comprising:

identifying a plurality of available cooperating devices associated with the source device;

selecting one of the available cooperating devices has a preferred connection to a destination device among the available cooperating devices;

transmitting data to the destination device; and

authorizing the selected cooperating device to retransmit the data to the destination device if the destination device fails to acknowledge receipt of the data transmitted from the source device.

2. A method as described in claim 1, wherein the available cooperating device is selected, at least in part, based on an expected transmission time between the cooperating device and the destination device that is less than an expected transmission time of one or more other said available cooperating devices.

3. A method as described in claim 2, wherein the expected transmission time is calculated as a reciprocal of an expected throughput on a given communication link between a transmitting device and a receiving device.

4. A method as described in claim 1, wherein authorizing the selected cooperating device to retransmit the data to the destination device permits the selected cooperating device to retransmit the data without further instruction by the source device.

5. One or more computer-readable media comprising processor-executable instructions that, when executed, direct a processor contained in a source device to:

establish a wireless connection between the source device and a destination device;

identify a plurality of available cooperating devices associated with the source device, wherein each of the available cooperating devices has established a wireless connection to the destination device;

determine a quality associated with each of the wireless connections between the available cooperating devices and the destination device;

select the cooperating device having the highest quality wireless connection with the destination device;

transmit data from the source device to the destination device; and

authorize the selected cooperating device to retransmit the data to the destination device if the destination device fails to acknowledge receipt of the data transmitted from the source device.

6. One or more computer-readable media as described in claim 5, wherein the quality associated with each of the wireless connections is determined based on an expected transmission time associated with each of the wireless connections.

7. One or more computer-readable media as described in claim 5, wherein the selected cooperating device is selected, at least in part, based on an expected transmission time between the cooperating device and the destination device that is less than an expected transmission time of one or more other said available cooperating devices.

8. One or more computer-readable media as described in claim 5, wherein data transmitted from the source device to the destination device is encoded using a first encoding technique.

9. One or more computer-readable media as described in claim 5, wherein data transmitted from the source device to the destination device is encoded using a first encoding technique.

10. One or more computer-readable media as described in claim 5, wherein data transmitted from the selected cooperating device to the destination device is encoded using a first encoding technique.

11. One or more computer-readable media as described in claim 5, wherein the data transmitted from the source device to the destination device is encoded using a first encoding technique and data transmitted from the selected cooperating device to the destination device is encoded using a second encoding technique.

12. One or more computer-readable media as described in claim 5, wherein:

wherein the data transmitted from the source device to the destination device is encoded using a first encoding technique; and

wherein the data transmitted from the selected cooperating device to the destination device is encoded using the first encoding technique.

13. One or more computer-readable media as described in claim 5, wherein the selected cooperating device is authorized to retransmit data without further instruction by the source device.

14. An apparatus comprising:

a communication module; and

a processor to couple to the communication module and configured to communicate with a number of cooperating devices, each of which is to communication with a destination device, the processor further configured to establish a wireless connection between the apparatus and the destination device and to select one of the cooperating devices to retransmit data to the destination device when an acknowledgment is not received, and wherein the processor is to select one of the cooperating devices by determining which cooperating device has a preferred wireless connection with the destination device.

15. An apparatus as described in claim 14, wherein the communication module includes a dipole antenna.

16. An apparatus as described in claim 14, wherein the data transmitted from the apparatus to the destination device is encoded using a first encoding technique and retransmitted data from the selected cooperating device to the destination device is encoded using the first encoding technique.

17. An apparatus as described in claim 14, wherein the processor is to select one of the cooperating devices by associating an expected transmission time metric with each cooperating device, otherwise the processor is to select no cooperating device if the wireless connection between the apparatus and the destination device has a smallest expected transmission time metric than the cooperating devices;

and

selecting a cooperating device having the smallest associated expected transmission time metric if the smallest expected transmission time metric is less than the expected transmission time metric associated with the wireless connection between the apparatus and the destination device.

18. An apparatus as described in claim 14, wherein the processor is further configured to instruct the selected cooperating device to automatically retransmit data to the destination device upon determining that the data transmission from the apparatus to the destination device failed.

19. An apparatus comprising:

a communication module; and

a processor to couple to the communication module and configured to establish a wireless connection with a destination device, identify a plurality of available cooperating devices that have established a wireless connection to the destination device, determine a quality associated with each of the wireless connections;

select a particular said cooperating device with a respective said wireless connection that has a higher quality that other said wireless connections, transmit data to the destination device, and authorize the selected cooperating device to retransmit the data to the destination device if the destination device fails to acknowledge receipt of the transmitted data.

20. An apparatus as described in claim 19, wherein the communication module includes a plurality of antennas.

21. An apparatus as described in claim 19, wherein the quality associated with each of the wireless connections is determined based on an expected transmission time associated with each of the wireless connections.

22. An apparatus as described in claim 19, wherein the selected cooperating device is selected, at least in part, based on an expected transmission time between the cooperating device and the destination device that is less than an expected transmission time of one or more other said available cooperating devices.

23. An apparatus as described in claim 19, wherein the transmitted data is encoded using a first encoding technique.

24. An apparatus as described in claim 19, wherein the selected cooperating device is authorized to retransmit data without further instruction from the processor.
