| Abstract | In multi-source multi-relay wireless network, centralized relay selection schemes are difficult to realize because they usually require global information, which is hardly available due to the limited memory and latency in realistic systems. Meanwhile, in classical distributed relay selection schemes, each source selects its “best” relay merely based on the local channel information. However, such schemes may lead to the case that several sources simultaneously select the same “best” relay and therefore causes a bottleneck problem. In this paper, we propose an opportunistic distributed relay selection scheme. In this scheme, each source selects its “best” relay by jointing the channel information and local “topology” information which can greatly ease the bottleneck problem. We also propose a three-step distributed signal interaction protocol by which every source can acquire its local “topology” information. Finally, we show the advantages of our proposed scheme by comparing the simulation results with other methods. |

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.
