Abstract

Methods for coordinating access to a barrage relay networks are disclosed. For example, one disclosed method includes: receiving, by a first node, a first message from a second node on a network; suppressing transmission of messages by the first node; receiving, by the first node, a second message corresponding to the first message or waiting a sufficient amount of time without receipt of the second message; reactivating transmission of the messages by the first node.

Claims

1. A method for coordinating access to a barrage relay network comprising:

receiving, by a first node, a first message from a second node on the barrage relay network;

suppressing transmission of messages by the first node;

receiving, by the first node, a second message corresponding to the first message or waiting a sufficient amount of time without receipt of the second message; and

reactivating transmission of the messages by the first node.

2. The method of claim 1, wherein the sufficient amount of time is a number of timeslots on a request sub-channel.

3. The method of claim 1, wherein both the first message and the second message are transmitted over a common control channel.

4. The method of claim 1, wherein the barrage relay network comprises two channels.

5. The method of claim 4, wherein the barrage relay network comprises a data channel.

6. The method of claim 4, wherein the barrage relay network comprises a control channel.

7. The method of claim 6, wherein the control comprises one or more independent sub-channels.

8. The method of claim 7, wherein the control channel comprises a request sub-channel and a confirmation sub-channel.

9. The method of claim 8, wherein the first message comprise a message sent on the request sub-channel.

10. The method of claim 8, wherein the second message comprise a message sent on the confirmation sub-channel.

11. A method for coordinating access to a barrage relay network comprising:

transmitting, by a first node, a first message comprising a hop count field;

receiving the first message and determining a first distance in hops from the first node;

transmitting, by a second node, a second message comprising a hop count field; and

receiving the second message and determining a second distance in hops from the second node.

12. The method of claim 11, further comprising determining if the first distance plus the second distance is greater than the distance from the first node to the second node.

13. The method of claim 12, further comprising scheduling a transfer defined by the second message.

14. The method of claim 11, wherein the barrage relay network comprises two channels.

15. The method of claim 14, wherein the barrage relay network comprises a data channel.

16. The method of claim 14, wherein the barrage relay network comprise a control channel.

17. The method of claim 16, wherein the control channel comprises one or more independent sub-channels.

18. The method of claim 17, wherein the control channel comprises a request sub-channel and a confirmation sub-channel.

19. The method of claim 18, wherein the first message comprise a message sent on the request sub-channel.

20. The method of claim 18, wherein the second message comprise a message sent on the confirmation sub-channel.

21. A method for coordinating access to a barrage relay networking comprising:

transmitting, by a first node, a first message comprising a hop count field;

receiving the first message and determining a first distance in hops from the first node;

transmitting, by a second node, a second message comprising a hop count field and a potential start time;

receiving the second message;

determining a second distance in hops from the second node;

determining a third distance from the first node to the second node; and

receiving by the first node, the second message.

22. The method of claim 21, wherein the barrage relay network comprises a data channel and a control channel.

23. The method of claim 22, wherein the control channel comprises a request sub-channel and a confirmation sub-channel.

24. The method of claim 23, wherein the first message comprise a message sent on the request sub-channel.

25. The method of claim 23, wherein the second message comprise a message sent on the confirmation sub-channel.

26. The method of claim 21, further comprising:

transmitting, by the first node, a third message;

determining if the first distance plus the second distance equals the third distance from the first node to the second node plus one hop; and

rebroadcasting, by a receiving node, the third message.

27. The method of claim 26, wherein the third message comprises a message sent on a confirmation sub-channel.
