- A main challenge in all-IP networks is how to deliver realtime
services with suitable QoS while moving in the network.
Mobile IP (MIP) is the standard mobility management
protocol in IP system. However, MIP is unsuitable
for QoS-sensitive applications. Mobile IP Fast Authentication
Protocol (MIFA) is proposed to shorten the handoff
Although, MIFA presents a good solution to provide
seamless mobility, it supports no QoS. ReSsource reser-
Vation Protocol (RSVP) is a known IP-based reservation
mechanism. It is widely used to reserve resources on a
certain path of routers throughout the Internet. However,
RSVP does not notice the mobility of mobile devices.
In this paper we propose a new QoS-enabled mobility
management framework for IP-based networks. In this
framework we integrate MIFA with RSVP to support fast
QoS re-reservation during and after the movement. We
extend RSVP by adding a new object called Mobility Object.
MIFA messages are encapsulated in this object. Our
proposal enables the Correspondent Node to use the old
path while the new one is in progress. Thus, the time required
to establish a new reservation is hidden from the
application. Additionally, our proposal allows simple network
architectures and doesn’t introduce any new entities
to the network.
