“…Another disadvantage is that the FxRTO of a sender may not suit for various environments. K. Omae et al proposed an MN extension [10] employing a buffering function to improve the handoff performance. Before L2 handoff, the MN extension sets pre-buffer timer and then buffers the ACKs during the pre-buffer time.…”

Mobile IP solves the primary problem of routing IP packets to mobile nodes. However, when using TCP Vegas over a mobile network, Vegas responds to a handoff by invoking a congestion control algorithm, thereby resulting in a degraded end-to-end performance in a mobile network. Furthermore, in Mobile IP handoffs, packets could be lost during movement detection and registration. These packet losses result in long communication pause, and successive timeouts. Accordingly, to reduce packet losses and timeout interval, we propose Mobility-Vegas, which uses Layer 2 trigger to detect handoffs, decreases the source's sending rate to reduce packet loss, and halts the retransmission timer to avoid increasing timeout interval. The proposed mechanism maintains end-to-end semantics, and operates under the existing network infrastructure. Mobility-Vegas presents a simple modification in the two end sides of a connection. Simulation result demonstrates that Mobility-Vegas features higher performance than Vegas in Mobile IP networks.

“…Omae et al proposed and showed simulated results of a method to improve handoff performance in Mobile IPv6 networks with the use of a buffer implemented at the mobile node [12]. UDP and TCP packets are buffered in the mobile node in order to minimise packet loss in the event of a handoff.…”

This dissertation discusses mobility management in IP based wireless environments. Mobility management can include both handovers within one technology and selection of access technology in a heterogeneous overlapping environment. IETF has standardized Mobile IP and its IPv6 version for handling mobility management in the IP networks. Even though Mobile IPv6 handles mobility in an application transparent way, several unresolved problems remain. This dissertation focuses on minimizing the Mobile IPv6 handover delays and interface selection in heterogeneous wireless environments.An enhancement called Flow-based Fast Handover for Mobile IPv6 is presented for speeding up the Mobile IPv6 address registration phase. The address registration phase, and thus also packet loss, can be notably decreased. More importantly, the delay is not dependent on the distance of the Corresponding Nodes as is the case with Mobile IPv6. In addition, mechanisms to control Mobile IPv6 handovers to offer the users and applications a best access were researched. Real time information about the link status and quality as well as user preferences are taken into account in the interface selection. The objective is to offer an Always Best Connected access to the user, and seamless handovers.
