Abstract

Techniques of present disclosure are directed to methods of providing acoustic communication networks. For example, methods are provided for that include obtaining, at a first transceiver of a plurality of transceivers arranged within an installation pattern, a first acoustic signal provided by a second transceiver of the plurality of transceivers. A location of the first transceiver within a message distribution pattern is determined from the acoustic signal. A delay based upon the location of the first transceiver within the message distribution pattern is determined. Finally, a second acoustic signal corresponding to the first acoustic signal is provided from the first transceiver after the delay.

First claim

What is claimed is:

1. A method comprising:
obtaining, at a first transceiver of a plurality of transceivers arranged within an installation pattern, a first acoustic signal provided by a second transceiver of the plurality of transceivers, wherein the first acoustic signal is configured with data to be distributed throughout the plurality of transceivers;
determining, from the first acoustic signal configured with the data to be distributed throughout the plurality of transceivers and a location of the first transceiver within the installation pattern, a location of the first transceiver within a message distribution pattern;
determining a delay based upon the location of the first transceiver within the message distribution pattern; and
providing, from the first transceiver after the delay, a second acoustic signal corresponding to the first acoustic signal and comprising the data to be distributed throughout the plurality of transceivers.

2. The method of claim 1 , wherein the plurality of transceivers comprise an undersea communication network.

3. The method of claim 1 , wherein the installation pattern comprises a hexagonal grid.

4. The method of claim 3 , wherein the plurality of transceivers are substantially equally spaced within the hexagonal grid.

5. The method of claim 3 , wherein determining the location of the first transceiver within the message distribution pattern comprises determining a location of the first transceiver in the hexagonal grid relative to an origin of the first acoustic signal.

6. The method of claim 1 , wherein determining the delay comprises selecting among a long delay and a short delay based upon the location of the first transceiver within the message distribution pattern.

7. The method of claim 6 , wherein the short delay comprises at least one of a delay until a next transmission epoch after the first acoustic signal was obtained or a delay until a second transmission epoch after the first acoustic signal was obtained.

8. The method of claim 1 , wherein the second transceiver comprises an origin of the first acoustic signal.

9. The method of claim 1 , further comprising cryptographically verifying the first acoustic signal prior providing the second acoustic signal.

10. A system comprising:
a plurality of transceivers arranged in an installation pattern,
wherein each transceiver of the plurality of transceivers is configured to:
obtain a first acoustic signal from another of the plurality of transceivers, wherein the first acoustic signal is configured with data to be distributed throughout the plurality of transceivers;
determine, from the first acoustic signal configured with the data to be distributed throughout the plurality of transceivers and a location of the transceiver within the installation pattern, a location of the transceiver within a message distribution pattern;
determine a delay based upon the location within the message distribution pattern; and
provide, after the delay, a second acoustic signal corresponding to the first acoustic signal and comprising the data to be distributed throughout the plurality of transceivers.

11. The system of claim 10 , wherein the plurality of transceivers comprise an undersea communication network.

12. The system of claim 10 , wherein the installation pattern comprises a hexagonal grid.

13. The system of claim 12 , wherein the plurality of transceivers are substantially equally spaced within the hexagonal grid.

14. The system of claim 12 , wherein each transceiver of the plurality of transceivers is configured to determine the location of the transceiver within the message distribution pattern by determining a location in the hexagonal grid relative to an origin of the first acoustic signal.

15. The system of claim 10 , wherein each transceiver of the plurality of transceivers is configured to determine the delay by selecting among a long delay and a short delay based upon the location of the transceiver within the message distribution pattern.

16. The system of claim 15 , wherein the short delay comprises at least one of a delay until a next transmission epoch after the first acoustic signal was obtained or a delay until a second transmission epoch after the first acoustic signal was obtained.

17. The system of claim 10 , wherein each transceiver of the plurality of transceivers is configured to cryptographically verify the first acoustic signal prior providing the second acoustic signal.

18. An apparatus comprising:
one or more speakers;
one or more microphones; and
one or more processors configured to:
obtain, via the one or more microphones, a first acoustic signal from a transceiver of a plurality of transceivers arranged in an installation pattern, wherein the first acoustic signal is configured with data to be distributed throughout the plurality of transceivers;
determine, from the first acoustic signal configured with the data to be distributed throughout the plurality of transceivers, a location of the apparatus within a message distribution pattern;
determine a delay based upon the location of the apparatus within the message distribution pattern; and
provide, via the one or more speakers after the delay, a second acoustic signal corresponding to the first acoustic signal and comprising the data to be distributed throughout the plurality of transceivers.

19. The apparatus of claim 18 , wherein the plurality of transceivers comprise an undersea communication network.

20. The apparatus of claim 18 , wherein the one or more processors are configured to determine the delay by selecting among a long delay and a short delay.
