| Abstract | In this paper, a general quality model for scalable coded video streaming over wireless mesh networks is applied in the paper for determining the cross-layer transmission strategies over wireless multi-hop networks. Our proposed solution is enabled by the scalable coding of the video content (i. e. users can transmit and consume video at different quality layers). The adaptive cross-layer strategies - application layer packet scheduling, the policy for choosing a relay, the MAC retransmission strategies, the PHY modulation and coding schemes - are determined per packet, at each intermediate node of the network, in a distributed manner. Unlike the conventional end-to-end flow-based centralized approach, the main component of the proposed solution is a distributed dynamic routing algorithm, called self-learning policy which selects the routing relays and the corresponding time allocation for the various packets. We show that our proposed dynamic routing approach significantly outperforms the static optimization algorithm, since it provides the ability to alleviate the congestion in the changing network. |

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.
