| Abstract | To provide live streaming service to mobile users, traditionally each user pulls content from a server over his cellular network. In order to overcome the scalability problem of last-hop bandwidth bottleneck, mobile peer-to-peer (P2P) streaming can be used where mobile devices relay their stream received in a multi-hop manner by means of a secondary channel (such as Wi-Fi or bluetooth). We investigate the design of distributed algorithm termed LocalTree, which minimizes the number of broadcasters while meeting a certain video quality requirement under peer churns. We first formulate the problem and show that it is NP-hard, and hence propose LocalTree which achieves robustness similar to an unstructured mesh and low delay similar to a global tree. Simulation results show that LocalTree outperforms other algorithms substantially in terms of number of broadcasters used (by as much as 50%). |

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.
