Methods and systems for network coordination
Aspects of the present invention relate to distributed network coordination and administration. Some aspects relate to network coordination and management using an interfering network list that may be maintained by a network controlling authority. Some aspects relate to allocation of specific bandwidth segments by a network controlling authority to avoid network collisions and improve network efficiency.
1. A method for distributed coordination of multiple interfering networks, said method comprising:
a) establishing a network controlling authority for a network;
b) searching for an interfering network;
c) receiving an interfering network list (INL) for said interfering network, said INL comprising an identification of said interfering network when said interfering network is present;
d) transmitting an INL for said network to said interfering network, said INL comprising identification of networks interfering with said network; and
e) communicating with an interfering network controlling authority for said interfering network to allocate specific bandwidth segments for exclusive use by one of said interfering network and said network.
2. A method as described in claim 1 wherein said network controlling authority is a Quality of Service Controller (QoSC).
3. A method as described in claim 1 wherein said searching comprises listening for a Beacon Protocol Data Unit (PDU) from said interfering network.
4. A method as described in claim 1 wherein said INL for said network is created by compiling data from at least one Beacon Protocol Data Unit (PDU).
5. A method as described in claim 1 wherein said communicating comprises establishing a Contention Free Period (CFP) for exclusive use by one of said network or said interfering network.
6. A method for distributed coordination of a network, said method comprising:
a) receiving a beacon from an interfering network controller (INC);
b) requesting an interfering network list (INL) from said INC;
c) selecting a network identification and a beacon slot that is not used in said INL; and
d) coordinating communication with said INC.
7. A method for distributed coordination of multiple interfering networks, said method comprising:
a) establishing a network controlling authority (NCA) for a network;
b) performing a beacon detection process with said NCA to detect an interfering network;
c) requesting, via said NCA, an interfering network list (INL) comprising an identification of an interfering network when said interfering network is present;
d) receiving, via said NCA, said interfering network list (INL) when said interfering network is present;
e) coordinating network communication with said interfering network to reduce interference-related transmission losses.
8. A method as described in claim 7 wherein said INL comprises beacon slot information and network identification information.
9. A method as described in claim 7 wherein said coordinating comprises establishing a contention-free period.
10. A method for distributed coordination of multiple interfering networks, said method comprising:
a) establishing a first network controlling authority (NCA) for a first interfering network;
b) establishing a second NCA for a second interfering network,
c) receiving a beacon message at said second NCA from said first NCA
d) requesting, via said second NCA, a first interfering network list (INL) for said first network;
e) receiving, at said second NCA, said first INL;
f) establishing a transmission schedule for said first and second interfering networks to reduce interference-related transmission losses.
11. A method as described in claim 10 wherein said establishing a transmission schedule comprises sending a new network request from said second NCA to said first NCA.
12. A method for distributed coordination of multiple interfering networks, said method comprising:
a) establishing a first network controlling authority (NCA) for a first interfering network;
b) establishing a second NCA for a second interfering network,
c) receiving a beacon message at said second NCA from said first NCA
d) requesting, via said second NCA, a first interfering network list (INL) for said first interfering network;
e) receiving, at said second NCA, said first interfering network list (INL);
f) establishing a transmission schedule for said first and second interfering networks to reduce interference-related transmission losses, wherein said establishing a transmission schedule comprises sending an add bandwidth request from said second NCA to said first NCA.
13. A method for distributed coordination of multiple interfering networks, said method comprising:
a) establishing a first network controlling authority (NCA) for a first interfering network;
b) establishing a second NCA for a second interfering network,
c) receiving a beacon message at said second NCA from said first NCA
d) requesting, via said second NCA, a first interfering network list (INL) for said first interfering network;
e) receiving, at said second NCA, said first interfering network list (INL);
f) establishing a transmission schedule for said first and second interfering networks to reduce interference-related transmission losses, wherein said establishing a transmission schedule comprises sending an add bandwidth request from said second NCA to said first NCA, sending an add bandwidth response from said first NCA to said second NCA and sending an add bandwidth confirmation from said second NCA to said first NCA.
14. A method for distributed coordination of multiple interfering networks, said method comprising:
a) establishing a first network controlling authority (NCA) for a first interfering network;
b) establishing a second NCA for a second interfering network,
c) receiving a beacon message at said second NCA from said first NCA
d) requesting, via said second NCA, a first interfering network list (INL) for said first interfering network;
e) receiving, at said second NCA, said first interfering network list (INL);
f) establishing a transmission schedule for said first and second interfering networks to reduce interference-related transmission losses, wherein said establishing a transmission schedule comprises sending a new network request from said second NCA to said first NCA, sending a new network response from said first NCA to said second NCA and sending a new network confirmation from said second NCA to said first NCA.
