| Abstract | As WDM-based optical networks are becoming the right choice for the next-generation Internet networks to transport high-speed IP traffic, the leading role of wireless ATM (WATM) networks will be undoubtedly replaced with wireless WDM (WWDM) networks for providing high quality of services to mobile users. Meanwhile, multicasting has played an increasingly important role in many conventional and emerging applications, such as teleconferencing and distributed games. In this paper, a constrained optical tree migration scheme (COTMS) is proposed to support multicast services in WWDM networks. COTMS is an enhancement of our previous work, called CTMS, for adapting to the characteristic of WDM-based backbone networks. CTMS can properly deal with the constrained tree migration problem for generic wireless networks, and COTMS inherits the efficiencies of CTMS entirely. Simulation results show that COTMS can markedly reduce the resources used per multicast tree, thus achieving both low handoff-dropping/join-blocking rate and high resource utilization. More importantly, we demonstrate how COTMS incorporating crossover optical switch discovery can be used to support real-time traffic for heterogeneous (i.e., unicast and multicast) connections in a uniform and unified manner. The proposed scheme is also suitable for routing over fully mobile (ad hoc) networks in which multiple frequencies are used for data communications. |

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.
