IEEE 802.11 is a widely used wireless LAN standard which offers a good bandwidth at low cost In an ESS, multiple APs can co-exist with overlapping coverage area. A mobile node connects to the AP from which it receives the best signal. Changes in traffic to and from different MNs occur over time. Load imbalance may develop on different APs. Throughput and delay of the different flows passing through the APs, where the load has increased beyond certain limit, may degrade. Different MNs associated to the overloaded APs will experience performance degradation.
