In the few last years, the deployment of IEEE 802.11 WLAN in hotspots environment had becoming a useful solution providing practical and attractive communication characteristics. However the problem of user bandwidth availability arises as one of the most limit of this solution. In fact, the IEEE 802.11 standards do not provide any mechanism of load distribution among different access points (APs)...
