| Abstract | Video streaming over wireless networks is inherently vulnerable to burst packet losses caused by dynamic wireless channel variations with time-varying fading and interference. To alleviate this limitation, especially in the transport layer, the error control schemes based on FEC (forward error correction), ARQ (automatic repeat request), interleaving, and their hybrid are essential. However, each error control mode shows different performance according to the target application requirement and the channel status. Thus, in this paper, we propose a network-adaptive selection of transport error control (NASTE), where transport-layer error control modes are dynamically selected and applied. First, an effective embedded (software-based) realization of error control modes is proposed to support the flexible mode switching for NASTE. We then present a practical yet effective mode switching algorithm by linking channel/application monitoring, table-guided mode switching decision, and subsequent fine-tuning on error-control mode parameters. Finally, we have implemented a prototype video streaming system with NASTE support and verified it over an IEEE 802.11 g WLAN (wireless LAN) environment. The experimental results indicate that the proposed mechanism can enhance the overall transport performance by recovering packet losses and thus improves the quality of video streaming over WLAN. |

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.
