Localized Mobility Management Requirements (Obsolete) |
|
Description: This document describes goals for Localized Mobility Management (LMM)
for IP layer mobility, such as in Mobile IP and Mobile IPv6. These
goals are intended to guide the design of a protocol specification
for LMM. Localized Mobility Management, in general, introduces
enhancements to IP layer mobility protocols to reduce the amount of
latency in IP layer mobility management messages exchanged between a
Mobile Node (MN) and its peer entities. In addition, LMM seeks to
reduce the amount of signaling over the global Internet when a mobile
node traverses within a defined local domain. The identified goals
are essential for localized mobility management functionality. They
are intended to be used as a guide for analysis on the observed
benefits over the identified goals for architecting and deploying LMM
schemes.

Enhanced Forwarding from the Previous Care-of Address for Fast Mobile IPv6 Handovers (Obsolete) |
|
Description: We introduce Enhanced Forwarding from the Previous Care-of Address
(eFWD) for fast handovers in Mobile IPv6. eFWD enables a mobile node
to create and directly control a bi-directional tunnel between the
mobile nodeÆs previous and new subnetÆs access routers subsequent to
a link layer handover. eFWD reduces handover latency by expediting
the mobile node's movement detection and new subnet's access router
discovery via proposed Candidate Access Router Information Discovery
(CARID) method and by eliminating time to acquire a new care-of
address. Main advantage of eFWD is complete removal of link layer
pre-triggers that are extremely complex mechanisms to implement in
wireless technologies other than cellular systems.
