US 20150208426 A1
computing topological metrics based at least in part on communication topology of a plurality of internal access points enabled to participate in a wireless network on at least one channel of a plurality of channels;
determining, based at least in part on the topological metrics, assignments of the plurality of channels to each of the internal access points; and
wherein the topological metrics comprise how many external neighbor access points there are for a particular one of the internal access points, each of the external neighbor access points not operating in the wireless network.
3. The method of claim 2, wherein the determining is further based at least in part on how many of the internal access points are within one hop and within two hops of a particular one of the internal access points and with respect to a particular one of the plurality of channels.
4. The method of claim 3, wherein the computing and the determining are performed by the particular internal access point.
5. The method of claim 2, wherein the determining is further based at least in part on recognition of reception errors.
6. The method of claim 5, wherein the reception errors are classified as one or more of interference, weak signal strength, unknown encoding, non-information, and noise.
7. The method of claim 2, wherein the determining is further based at least in part on recognition of transmissions from devices not participating in the wireless network as interference.
8. The method of claim 2, wherein the determining is further based at least in part on recognition of transmissions from non-networking devices as interference.
9. A non-transitory machine-readable medium having a set of instructions stored therein that when executed by a processing element cause the processing element to perform functions comprising:
10. The non-transitory machine-readable medium of claim 9, wherein the determining is further based at least in part on how many of the internal access points are within one hop and within two hops of a particular one of the internal access points and with respect to a particular one of the plurality of channels.
11. The non-transitory machine-readable medium of claim 10, wherein the particular internal access point comprises the processing element and the non-transitory machine-readable medium.
12. The non-transitory machine-readable medium of claim 9, wherein the determining is further based at least in part on recognition of reception errors.
13. The non-transitory machine-readable medium of claim 12, wherein the reception errors are classified as one or more of interference, weak signal strength, unknown encoding, non-information, and noise.
14. The non-transitory machine-readable medium of claim 9, wherein the determining is further based at least in part on recognition of transmissions from devices not participating in the wireless network as interference.
15. The non-transitory machine-readable medium of claim 9, wherein the determining is further based at least in part on recognition of transmissions from non-networking devices as interference.
wherein the memory stores instructions that when executed by the processor enable the processor to perform functions comprising:
17. The apparatus of claim 16, wherein the determining is further based at least in part on how many of the internal access points are within one hop and within two hops of a particular one of the internal access points and with respect to a particular one of the plurality of channels.
18. The apparatus of claim 17, wherein the particular internal access point comprises the apparatus.
19. The apparatus of claim 16, wherein the determining is further based at least in part on recognition of reception errors as one or more of interference, weak signal strength, unknown encoding, non-information, and noise.
means for computing topological metrics based at least in part on communication topology of a plurality of internal access points enabled to participate in a wireless network on at least one channel of a plurality of channels;
means for determining, based at least in part on the topological metrics, assignments of the plurality of channels to each of the internal access points; and
21. The system of claim 20, wherein the means for determining is further based at least in part on how many of the internal access points are within one hop and within two hops of a particular one of the internal access points and with respect to a particular one of the plurality of channels.
