| Abstract | Energy conservation is one of the most important challenges in wireless sensor networks. In more applications, sensor networks are composed of hundreds or thousands nodes which are dispersed in a wide field. In large-scale sensor networks, hierarchical architecture and data aggregation are effective approaches to prolong the lifetime of the network as long as possible. Clustering is a well-known two-layered architecture that has been extremely investigated for wireless sensor networks by researchers as yet. In this paper, we propose a novel adaptive Energy-Efficient Multi-layered Architecture (EEMA) protocol for large-scale sensor networks, where utilizes both hierarchical architecture and data aggregation mechanisms efficiently. In EEMA, the network is divided into some layers that the data are gathered in the first layer, and are aggregated in the next layers to reach the base station. Also each layer is segmented into some groups as clusters. EEMA selects the nodes with the proper residual energy, centrality, and proximity to the other neighboring heads as the head of each group. Performance evaluation is performed via simulations which confirms the effectiveness of the proposed EEMA protocol in terms of the network lifetime and reduced routing delay, in contrast with the existing hierarchical approaches for large-scale sensor networks. |

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.
