A Framework of Media-Independent Pre-Authentication (MPA) for
Inter-Domain Handover Optimization
Abstract
This document describes Media-independent Pre-Authentication (MPA), a
new handover optimization mechanism that addresses the issues on
existing mobility management protocols and mobility optimization
mechanisms to support inter-domain handover. MPA is a mobile-
assisted, secure handover optimization scheme that works over any
link layer and with any mobility management protocol, and is most
applicable to supporting optimization during inter-domain handover.
MPA's pre-authentication, pre-configuration, and proactive handover
techniques allow many of the handoff-related operations to take place
before the mobile node has moved to the new network. We describe the
details of all the associated techniques and their applicability for
different scenarios involving various mobility protocols during
inter-domain handover. We have implemented the MPA mechanism for
various network-layer and application-layer mobility protocols, and
we report a summary of experimental performance results in this
document.

Research Group.
