| Abstract | A new cooperative multiple-access protocol is proposed in which a relay utilizes the empty time slots available in a TDMA frame. In particular, the relay helps the users in the network forwarding their unsuccessfully transmitted packets during the empty time slots. This will better utilize the channel resources that are otherwise wasted, and will introduce on-demand spatial diversity into the network. The proposed cooperation protocol is also different from those proposed in the literature as it does not result in any bandwidth loss. Two different protocols are proposed to implement this new multiple-access scheme, and their stability regions are characterized. The stability regions of the proposed protocols are shown to contain that of TDMA without relaying, hence, relay deployment in wireless networks can increase the network throughput capacity. Moreover, the analysis and numerical results reveal that the proposed cooperative multiple access protocols can simultaneously achieve higher stable throughput and less energy expenditure compared to TDMA without relaying. |

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.
