Abstract
One embodiment of the invention includes assigning channels to a set of access points coupled to a network. The network includes a set of wireless network nodes. Each access point communicates, using one of the channels, to a subset of the wireless network nodes. Each channel corresponds to a different frequency range in the electromagnetic spectrum. The embodiment includes the following steps. At least a first access point of the set of access points transmits a plurality of messages. A measure of interference between access points communicating on a first channel is determined from the plurality of messages. A second set of channel assignments, that results in a lower amount of interference between access points communicating on the first channel, is determined. The second set of channel assignments is assigned to the set of access points. Thus, non-interfering frequency assignments for the access points can be determined.
