Mobile Information Centre -- An Approach to Fast Handoff

In 802.11 based wireless networks, the mobile nodes (MN) are associated with the available Access Points (APs) and communicate through them. In conventional handoff schemes, the mobile nodes receives the information regarding active APs in their neighbourhood by scanning the available channels and listen to transmitted beacons. In this paper a new handoff agent, specifically designed to reduce authentication delay during handoff, is introduced to enhance handoff speed.
