| Abstract | This work addresses the problem of a fast hybrid automatic-repeat-request (HARQ) scheme intended for transporting delay-sensitive flows in a cooperative diversity (CD) environment. This CD with fast HARQ scheme allows the retransmission for only one time via the cooperating user (i.e. partner) or via both the sender and the partner simultaneously. A complementary link packet is used for retransmissions. The retransmission policy can be adjusted based on the qualities of channels among the sender, the partner, and the receiver and the application layer protocol data unit size by using the application throughput as the objective. For this presented scheme, we completely derive the application throughput formulas, which are then validated via simulations. Next, the CD with optimized fast HARQ scheme is shown able to achieve better throughput than effective throughput of other CD with ARQ schemes in various Nakagami-m slow-fading environments. As a result, the fast HARQ scheme should be an excellent ARQ mechanism for the real-time multimedia transport in CD environments. |

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.
