Systems and methods for network coordination with limited explicit message exchange
Embodiments of the present invention comprise methods and systems for coordination of interfering network devices.
1. A method for coordinating potentially-interfering networks, said method comprising:
a) initializing a first network, wherein said initializing comprises decoding all existing network beacons received at said first network during said initializing and determining an interfering network list associated with said first network from said decoded network beacons
b) receiving, at said first network, a second-network beacon from a second network, wherein said first network and said second network are neighboring networks;
c) decoding, at said first network, said second-network beacon to ascertain network scheduling information for said second network;
d) adjusting bandwidth assignments for said first network to coordinate with said network scheduling information for said second network; and
e) based on said network scheduling information for said second network, updating said interfering network list associated with said first network.
2. A method as described in claim 1 wherein said network scheduling information for said second network comprises scheduled transmission periods for said second network.
3. A method as described in claim 1 wherein said network scheduling information for said second network comprises device identification and device bandwidth allocations.
4. A method as described in claim 1 wherein said adjusting comprises releasing bandwidth previously reserved by said first network.
5. A method as described in claim 1 , wherein said determining, said receiving, said decoding, said adjusting and said updating are performed by a controlling authority for said first network.
6. A method as described in claim 5 , wherein said controlling authority is a Quality of Service Controller (QoSC) for said first network.
7. A method as described in claim 1 , wherein said receiving, said decoding and said adjusting are performed by a controlling authority for said first network.
8. A method as described in claim 7 , wherein said controlling authority is a Quality of Service Controller (QoSC) for said first network.
9. A method as described in claim 1 further comprising:
a) receiving, at said first network, a third-network beacon from a third network, wherein said first network and said third network are neighboring networks;
b) decoding, at said first network, said third-network beacon to ascertain network scheduling information for said third network;
c) adjusting bandwidth assignments for said first network to coordinate with said network scheduling information for said third network; and
d) based on said scheduling information for said third network, updating said interfering network list associated with said first network.
10. A method as described in claim 9 , wherein said adjusting bandwidth assignments for said first network to coordinate with said network scheduling information for said second network and said adjusting bandwidth assignments for said first network to coordinate with said network scheduling information for said third network comprises forming the union of said network scheduling information for said second network and said network scheduling information for said third network.
