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: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
