| Abstract | We propose an active buffer management scheme to guarantee quality of service (QoS) for video streaming services in wireless local area network (WLAN). The proposed scheme uses the concept of virtual transmission delay and differentiates the frame drop policy according to the type of video frame. The virtual transmission delay is defined as the delay until the video frame is potentially transmitted since a frame is arrived at the buffer. By the simulation result, the frame transmission delay does not exceed the delay bound when the proposed scheme is used. As a result, the number of frames of degraded peak signal to noise ratio (PSNR) is reduced about 50% compared to the case that the conventional Enhanced Distributed Channel Access (EDCA) is used. The proposed protocol also outperforms the EDCA in the actually visual quality of video streaming. |

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.
