An Enhanced Mobile IPv6 with Multicast Function and Hierarchical Design

01.07.2008
The present invention relates to Internet Protocol version six (IPv6) as a wireless network infrastructure. The use of this technology is expected to guarantee no packet loss while reducing handover delay by 94.32% and packet delay by 84.43% during handover.

The present invention relates to Internet Protocol version six (IPv6) as a wireless network infrastructure. More particularly, it provides a method to improve the handover delay in Mobile IPv6 so as to offer uninterrupted on-line experience in internet-based applications such as in entertainment, games, video conferencing or video streaming while on the move.

Mobile IPv6 (MIPv6) mechanism requires some handover algorithm when it changes its point of attachment in the Internet. This causes mobile IPv6 to incur long delays and high signalling load to the backbone networks and the attendant packet loss. This limitation is due to:

(i) the lack of hierarchy and fast handover mechanism in the mobile IPv6 mobility management, and

(ii) it addresses the micro mobility in the same way as macro mobility while from a recent survey 80% of the mobile users stay in micro mobility environment (i.e. in the same domain under the same Multicast Router).

An enhanced micro mobility handover algorithm is developed on top of mobile IPv6. This invention solves the problem of long delay and packet loss incurred during handover through enhancement of handover management in Mobile IPv6. It integrates hierarchical concept and multicast function. Hierarchical design is used to shield the micro mobility from macro mobility in order to reduce location update signal and signalling traffic within micro level network while multicasting is used to send packets to Mobile Node (MN) through base stations that are near to MN. This reduces handover delay that causes packet lost when MN is roaming.

A representative system (real-time test-bed) comprises of both software and a hardware element has been developed. Through the test-bed, it is shown that handover delay, packet loss and signalling traffic can be improved in average by 90% over the presently used Mobile IPv6.

The use of the technology of this invention is expected to guarantee no packet loss while reducing handover delay by 94.32% and packet delay by 84.43% during handover. This product is patent-pending (PI 20062478).

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
