Experimental Performances Analysis of Load Balancing Algorithms in IEEE 802.11

In IEEE 802.11, load balancing algorithms (LBA) consider only the associated stations to balance th e load of the available access points (APs). However, althoug h the APs are balanced, it causes a bad situation if the AP h as a lower signal length (SNR) less than the neighbor APs. So, balance the load and associate one mobile station to an acc ess point without care about the signal to noise ratio (SNR) of the AP cause possibly an unforeseen QoS; such as the bit r ate, the end to end delay, the packet loss, … In this way, w e study an improvement load balancing algorithm with SNR integration at the selection policy.
