About the Project
• We are developing models for simulating Mobile IPv6 networks. These models will be used to analyse
the performance of Mobile IPv6 protocols in large scale networking scenarios.
• We use parametric simulation techniques on the simulation model to obtain performance statistics.
• We are using the VPAC supercomputing facility comprised of 128 Compaq Alpha CPUs.
• The main simulation software tool used is OMNeT++ (Objective Modular Network Testbed in C++).
What is Mobile IPv6?
Mobile IP is the IETF proposed standard solution for handling terminal mobility among IP subnets and
was designed to allow a host to change its point-of-attachment transparently to an IP network.
The generic problem with traditional IP mobility is
that when an IP node moves to a new subnet, it has
to change its IP address to reflect the new point-ofattachment. However, the transport layer uses the IP
address as an identifier for managing the
communication with the peer process. If the IP
address changes, the transport layer connection to
the peer process is lost, and the session will need to
be re-established.
The transport and application layer processes
then continue using the home address
transparently and they remain unaware of the
changing care-of address as the Mobile Node
(MN) moves out of its home network.
Mobile IP solves the mobility problem by managing
the logical connectivity between a hanging IP
address (care-of-address) and the static home
address.
Conclusion
Mobile IPv6 at the network layer solves the handover problem in the wireless environment. Mobile IPv6
provides IP address transparency to the upper layers which they use IP addresses as identifiers for
identification of the peer sessions. The trend of integrating mobile telecommunications and IP networks is
gaining momentum and Mobile IPv6 will therefore serve an important role in the 3rd generation mobile
network.
