Abstract:
1. A method for assigning channels to access points (APs) in a wireless network, the method comprising: determining, by a computer system, at least one bottleneck client in an interference relationship, wherein the interference relationship is with a node in the wireless network or the interference relationship is between an AP associated with the bottleneck client and a node in the wireless network; determining a new channel assignment for a set of channels, wherein the new channel assignment includes different channels assigned to APs in the interference relationship; applying constraints to all APs and clients in the interference relationship; determining a normalized throughput for the at least one bottleneck client by applying the constraints; repeating the steps of determining a new channel assignment, applying constraints and determining the normalized throughput for different channel assignments until a maximum normalized throughput is determined; assigning the normalized throughput to the at least bottleneck client; and assigning the at least one bottleneck client to a fixed set of normalized throughputs.
