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).

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
