"Presently, IEEE 802.11 based Wireless Local Area Networks (WLANs) have been widely deployed for business and personal applications. The main issue regarding wireless network technology is handoff or hand over management. When a Mobile Station (MS) moves outside the range of its current Access Point (AP) it needs to perform a link layer handover. This causes data loss and interruption in communication. According to IEEE 802.11, link Layer2 (L2) handoff is performed in three phases - scanning, authentication and re-association. Scanning process causes 90% of the total handoff delay."
