A fast active scanning algorithm is proposed for IEEE 802.11 handoff.Firstly,the STA select the scanned APs from neighbor AP graph with location information;Second,the STA begin to probe the APs using uni-cast way.The algorithm reduces the delay which is brought by wasted channels,waited time and collisions.Simulation shows that the algorithm not only finishes the handoff but also reduces remarkably the latency.

Key words: IEEE 802.11;handoff;active scanning algorithm;neighbor AP graph
