| Abstract | There is on-going convergence of IP and traditional telecommunication networks (both wired and wireless). To facilitate fast handoff and real-time location tracking, and reduce the location update overhead in IP based mobile networks, hierarchical IP mobility management schemes, i.e., Mobile IP for macro-mobility (inter mobile domains) and cellular-network-optimized schemes for micro-mobility within mobile domains, are needed. In this paper, we apply the connection tree concept that was originally proposed for wireless ATM networks to IP micro-mobility management for mobile users with QoS requirements by using such new concepts as virtual multicast, virtual sender/receiver, null filter spec and dormant reservation. Our scheme enables fast and smooth handoff by localizing most of the location update related operation and pre-establishing connections to/from multiple base stations. It integrates seamlessly with such IP QoS mechanisms as RSVP, enables quick reservation restoration during handoff, and naturally supports soft handoff. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
