Optimizing the Performance of Handoff Management in Wireless LANs
Overview As the radio range of Access Point (AP) in a Wireless Local Area Network (WLAN) is about 35 meters, Mobile Nodes (MNs) have to frequently undergo a handoff process when they move beyond the radio coverage area of their associated APs. However, legacy IEEE 802.11-based standards cannot provide sufficient support for mobility management. Besides, as the demands from wireless users for real-time multimedia services increase, quality of service provisioning becomes a challenging issue for mobile users in WLANs. Under the circumstances, this paper proposes a new handoff management scheme to support ongoing real-time applications while MNs change their network attachment points. This MAC-layer-based approach consists of minimizing the total number of scanned channels during handoff, and reducing the probe-waiting time for each examined channel.
