"Mobile IPv6 Fast Handovers over IEEE 802.16e Networks", Hee-Jin Jang, Junghoon Jee, Youn-Hee Han, Soohong Daniel Park, Jaesun Cha, 10-Mar-08. ( bytes)

This document describes how a Mobile IPv6 Fast Handover can be implemented on link layers conforming to the IEEE 802.16e suite of specifications. The proposed scheme tries to achieve seamless handover by exploiting the link-layer handover indicators and thereby synchronizing the IEEE 802.16e handover procedures with the Mobile IPv6 fast handover procedures efficiently.

"Mobile IPv6 Fast Handovers for 3G CDMA Networks", Hidetoshi Yokota, Gopal Dommety, 13-Apr-08. ( bytes)

Mobile IPv6 is designed to maintain its connectivity while moving from one network to another. It is adopted in 3G CDMA networks as a way to maintain connectivity when the mobile node moves between access routers. However, this handover procedure requires not only movement detection by the MN, but also the acquisition of a new care-of address and Mobile IPv6 registration with the new care-of address before the traffic can be sent or received in the target network. During this period, packets destined for the mobile node may be lost, which may not be acceptable for real-time application such as Voice over IP (VoIP) or video telephony. This document specifies fast handover methods in the 3G CDMA networks in order to reduce latency and packet loss during handover.

"Mobile IPv6 Fast Handovers", Rajeev Koodli, 17-Apr-08. ( bytes)

Mobile IPv6 enables a Mobile Node to maintain its connectivity to the Internet when moving from one Access Router to another, a process referred to as handover. During handover, there is a period during which the Mobile Node is unable to send or receive packets because of link switching delay and IP protocol operations. This "handover latency" resulting from standard Mobile IPv6 procedures, namely movement detection, new Care of Address configuration, and Binding Update, is often unacceptable to real-time traffic such as Voice over IP. Reducing the handover latency could be beneficial to non-real- time, throughput-sensitive applications as well. This document specifies a protocol to improve handover latency due to Mobile IPv6 procedures. This document does not address improving the link switching latency.

"Distributing a Symmetric FMIPv6 Handover Key using SEND", James Kempf, 31-Oct-07. ( bytes)

Fast Mobile IPv6 requires that a Fast Binding Update is secured using a security association shared between an Access Router and a Mobile Node in order to avoid certain attacks. In this document, a method for provisioning a shared key from the Access Router to the Mobile Node is defined to protect this signaling. The Mobile Node generates a public/private key pair using the same public key algorithm as for SEND (RFC 3971). The Mobile Node sends the public key to the Access Router. The Access Router encrypts a shared handover key using the public key and sends it back to the Mobile Node. The Mobile Node decrypts the shared handover key using the matching private key, and the handover key is then available for generating an authenticator on a Fast Binding Update. The Mobile Node and Access Router use the Router Solicitation for Proxy Advertisement and Proxy Router Advertisement from Fast Mobile IPv6 for the key exchange. The key exchange messages are required to have SEND security; that is, the source address is a Cryptographically Generated Address and the messages are signed using the CGA private key of the sending node. This allows the Access Router, prior to providing the shared handover key, to verify the authorization of the Mobile Node to claim the address so that the previous care-of CGA in the Fast Binding Update can act as the name of the key.

"Hierarchical Mobile IPv6 Mobility Management (HMIPv6)", Claude Castelluccia, 8-Apr-08. ( bytes)

This document introduces extensions to Mobile IPv6 and IPv6 Neighbour Discovery to allow for local mobility handling. Hierarchical mobility management for Mobile IPv6 is designed to reduce the amount of signalling between the Mobile Node, its Correspondent Nodes, and its Home Agent. The Mobility Anchor Point (MAP) described in this document can also be used to improve the performance of Mobile IPv6 in terms of handover speed.

"Mobility Services Framework Design", Telemaco Melia, Gabor Bajko, Subir Das, Nada Golmie, Juan Zuniga, 14-May-08. ( bytes)

This document describes a design solution for the IEEE 802.21 Media Independent Handover (MIH) protocol that addresses identified issues associated with the transport of MIH messages. The document describes mechanisms for mobility service (MoS) discovery and transport layer mechanisms for the reliable delivery of MIH messages.

"Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) Options for Mobility Server (MoS) discovery", Gabor Bajko, Subir Das, 19-Apr-08. ( bytes)

This document defines a number of Dynamic Host Configuration Protocol (DHCP-for-IPv4 and DHCP-for-IPv6) options that contain a list of domain names or IP addresses that can be mapped to servers providing IEEE 802.21 type of Mobility Services. These Mobility Services are used to assist an MN in handover preparation (network discovery) and handover decision (network selection). The services addressed by this document are the Media Independent Handover Services defined in [IEEE802.21].

"Locating Mobility Servers using DNS", Gabor Bajko, 19-Apr-08. ( bytes)

This document defines application service tags that allow service location without relying on rigid domain naming conventions, and DNS procedures for discovering servers which provide Mobility Services. Mobility Services are used to assist an MN in handover preparation (network discovery) and handover decision (network selection). The services addressed by this document are the Media Independent Handover Services defined in [1].
