	abstract = {One of the most critical issues in introducingWireless
LAN (WLAN) real-time and delay sensitive applications,
such asVoice over IP (VoIP), is guaranteeing IP service
continuation during inter-subnet Basic Service Set (BSS)
transitions. Even though WLANs offer very high channel
bandwidth, they exhibit long network-layer handoff latency.
This is a restraining factor for mobile clients using interactive
multimedia applications such as VoIP or video streaming.
In a previous work, we presented a novel fast and efficient
IP mobility solution, called ?IP-IAPP?, which offers
constant IP connectivity to the 802.11 mobile users and successfully
preserves their ongoing sessions, even during subnet
handoffs (fast recovery of active connections). It is an
802.11-dependent IP mobility solution, which accelerates
the network reconfiguration phase after subnet handoffs and
significantly reduces the IP handoff latency. It restores L3
connectivity almost simultaneously to the L2 connectivity
after a subnet handoff, due to a zero-delay movement detection
method. As a result, even the most demanding next generation WLAN applications such as Voice over WLAN
(VoWLAN) suffer insignificant disruption. In this paper we
present an improved version of the IP-IAPP mobility mechanism
(new optimized protocol procedures). Certain extensions
have also been incorporated to the initial proposal, for
the provision of more advanced services: (a) secure inter-AP
IP-IAPP communications, (b) zero patching on the clients
s/w, and (c) support of clients which use a dynamic IP address.
Performance measurements out of further and more
complex testing verify that the proposed method outperforms
other existing mobility solutions, and still introduces the
lesser imperative amendments to the existing 802.11 wireless
LAN framework.},

	abstract = {This paper presents an effective and simple solution to the problem of Layer 3 (L3) handover in IEEE 802.11 wireless LANs (WLANs), so as to extend the IP mobility area of 802.11 wireless Stations (STAs). The IEEE 802.11f Inter-Access Point Protocol (IAPP), handles the Layer 2 (L2) mobility of STAs during L2 (intra-network) handovers, and offers IP connectivity via L2 specific methods. Instead of using a different protocol for the L3 mobility management of STAs, such as Mobile IP (MIP) [4] or a MIP-variant, the IAPP protocol is extended so as to also support the inter-network (L3) movements of 802.11 STAs. The proposed IAPP-based mechanism supports host mobility and offers substantial uninterrupted wireless IP-connectivity, even after L3 movements. The cornerstones of this mechanism are the zero-delay IP movement detection and the zero over-the-air IP signaling during IP handover establishment, which lead to seamless (very fast) and smooth IP handoffs. This fast IP-handoff method is especially suitable to 802.11 systems, as it has better performance than traditional MIP-based methods (shorter handover delays, near zero packet loss), while makes IP roaming transparent to the mobile STAs.},
