Due to rapid growth in IEEE 802.11 based Wireless Local Area Networks (WLAN); handoff has become a burning issue. A Mobile Node (MN) requires handoff when it travels out of the coverage area of its current Access Point (AP) and tries to associate with another AP. But handoff delays provide a serious barrier for such services to be made available to mobile platforms. Throughout the last few years there has been plenty of research aimed towards reducing the handoff delay incurred in the various levels of wireless communication.
