Hierarchical channel assignment in wireless networks
First Claim
1. A computer-implemented method for performing channel assignments in a wireless network, the method comprising:
- identifying a plurality of wireless access points (APs) in the wireless network, each of the wireless APs being associated with an initial channel assignment;
selecting a first AP from among the plurality of wireless APs in the wireless network;
determining a channel quality for the initial channel assignment associated with the first AP;
first selecting a first new channel for the first AP based on the channel quality for the initial channel assignment associated with the first AP;
selecting a second AP from among the plurality of wireless APs in the wireless network;
determining a channel quality for the initial channel assignment associated with the second AP; and
second selecting a first new channel for the second AP based on the channel quality for the initial channel assignment associated with the second AP;
wherein each of the first and second selecting comprises;
estimating for a particular AP as Node P performance on a channel c with channel width cw using the relationship of

Abstract
Aspects of the disclosed technology address the problems of calculating and performing channel assignments for access points (APs) in a wireless network. In some aspects, a process for performing channel assignment can include steps for identifying multiple APs in a network, each of the wireless APs being associated with an initial channel assignment, selecting an AP from among the wireless APs in the network, determining a channel quality for the initial channel assignment associated with the AP, and selecting a new channel for the AP based on the channel quality. In some aspects, the process further includes steps for selecting a second AP, determining a channel quality for the initial channel assignment associated with the second AP, and selecting a new channel for the second AP based on the channel quality. Systems and machine-readable media are also provided.
