An Optimized Handoff Scheme For IP Mobility Support In IEEE 802.11 WLANs

This paper presents an 802.11-dependent IP mobility solution which accelerates the network reconfiguration phase after subnet handoffs and significantly reduces the IP handoff latency. The proposed fast IP handoff method offers the next generation WLAN applications such as Voice over WLANs (VoWLAN) complete freedom of movement without experiencing any connectivity problems. The performance results verify that this method outperforms other existing proposed IP mobility solutions in WLANs, in a way which introduces the lesser imperative amendments to the existing 802.11 wireless LAN framework
