| Abstract | An earthquake is caused by the sudden release of strain in the Earth's crust which results in waves of shaking that radiate outward from the earthquake source. During the last decade, several satellite experiments discovered new phenomena in the ionosphere and magnetosphere that had preceded earthquakes. In this research, we suggest a novel early warning system for earthquakes based on wireless sensor network (WSN). A WSN based on single antenna wireless sensor nodes are cooperating to establish a multiple-antenna WSN that is called virtual MIMO-WSN. Virtual MIMO-WSN has adjustable and tuning capabilities to monitor different frequencies based on the number of the cooperative wireless sensor nodes. An electromagnetic map could be generated by activating a virtual MIMO-WSN in specific direction (North-South, East-West, North-West, North-East, South-West, South-East) by switching (ON/OFF) certain sensor nodes based on their location. Cost effectiveness, system scalability, ease of deployment, adjustable frequency tuning, and reliable ELF/VLF direction finding are key design factors in virtual MIMO-WSN, overcoming the existing techniques for ELF/VLF monitoring systems. Simulation results show the effectiveness of the proposed virtual MIMO-WSN in adjustable frequency system tuning, and reliable ELF/VLF direction finding. |

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.
