| Abstract | We propose a cross-layer optimization framework for multi-session broadcast/multicast (BC/MC) over multimedia network. The proposed framework seeks to perform simultaneous adaptations via intelligent co-operations between satellite gateway, terrestrial gap-fillers and respective BC/MC receivers to cope with highly vibrating satellite link, which is severely constrained by propagation delay, transponder power and channel bandwidth. By jointly optimizing multiple performance criteria across protocol stacks, the scheme mitigates the adverse impacts induced by queuing dynamics, channel variations and user diversities, thereby encompassing channel-dependant and network-friendly features. Meanwhile, it well accommodates return link diversity and the imperfect feedbacks, whilst ensuring fairness, scalability and robustness. We evaluate its performance over diverse network and media configurations in comparison with the state-of-the-art approaches. Numerical results show that simultaneous performance gains can be obtained on multiple essential performance metrics. |

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.
