Geometrical Mathematical Models and Carrier to Interference Ratio Based Handoff Algorithm for Reduction of Handoff Latency in Wireless Networks

"IEEE 802.11b networks are becoming more ubiquitous. While roaming through access points, a mobile node is often required to perform a link layer handover. This mechanism causes connection losses and breaks in time-sensitive communication, especially if a network layer handover follows the link layer handover. In this paper, the authors propose to reduce handoff latency for IEEE 802.11 wireless networks with Neighbor Graphs (NG) pre-scanning mechanisms and using a GPS based server which predetermines the next probable AP using three formulated geometry based mathematical techniques. IEEE 802.11 uses 11 channels of which the channels 1, 6 and 11 do not mutually overlap."
