Handoff in Wireless Networks
Handoff call management plays a major role in supporting acceptable levels of Quality of Service (QoS). Connection rerouting involves: limited handoff latency, maintaining an efficient route, limiting disruption of continuous media traffic, and limiting network switch update rates due to rerouting. The approaches for connection rerouting are: optimistic handoff, ordered handoff, predictive handoff, and chaining handoff. The handoff call management scheme reduces signaling traffic in wireless network and improves efficiency of virtual channel.
