IEEE802.11 WLAN (Wireless LAN) has been widely used in enterprise and public space. The important aspect of such network is the efficient use of radio resources and optimal load balancing among APs (Access Point). In IEEE802.11, a STAtion (STA) or a node has the right to select an AP with which it will associate. In an IEEE 802.11 WLAN, a STAtion (STA) can be within the range of several Access Points (APs), and can associate with each one of these at a certain maximum physical bit rate, de-pending on various radios channel conditions. If STAs have no strategy for association, they may associate with one of the APs.
