Virtualization for Load Balancing on IEEE 802.11 Networks
In IEEE 802.11 networks composed by multiple APs, before a station can access the network it needs to make a decision about which AP to associate with. Usually, legacy 802.11 stations use no more than the signal strength of the frames received from each AP to support their decision. This can lead to an unbalanced distribution of stations among the APs, causing performance and unfairness problems. This paper proposes a new approach that combines the number of associated stations and the current load of each AP plus the virtualization of client wireless interfaces.
