Congestion level and signal quality based estimator for bit-rate and automated load balancing for wlans

摘要

A method and system for determining the bit-rate between a wireless station and one or more access points that takes into account the usage (congestion) of the access points. Each wireless station includes software and/or hardware for estimating the bit-rate between the wireless station and any available access points and provides automatic load balancing for the wireless network. Dual estimator and backpressure algorithms are utilized to better estimate the achievable bit-rate available to a wireless station associated with an access point and to provide congestion sensitive access point selection. Bandwidth estimation is provided while taking into account congestion information for building up associations to access points while automatically achieving load balancing of the traffic among available access points.
