A Virtual Access Point Based Fast Handoff Scheme of IEEE 802.11
In the fast growing wireless technologies, IEEE 802.11 handoff is a big issue in communication. The seamless handoff problem in WLANs is a very important design issue to support the new astounding and amazing applications in WLANs, particularly for a user in a mobile vehicle. The entire delay time of a handoff is divided into probe, authentication, and re-association delay times. Because the probe delay occupies most of the handoff delay time, efforts have mainly focused on reducing the probe delay to develop faster handoff schemes.
