| Abstract | In this paper, we address one of the wireless sensor network query processing issues posed due to the lack of support for multiple sensor network queries. The objective of the paper is to provide efficient and effective support to multiple queries so that the set of queries are pre-processed before disseminating them into the sensor network. It is very important that only necessary works will be assigned to the sensor network by virtue of strict energy constraint. The problem is modeled by minimum set cover, which is one of the NP-complete problems. We propose an optimization scheme called TAMPA - a tabu search-based multiple queries optimization to find an optimal merge order. The final set of queries to be sent into the network then can be derived from that merge order. We evaluate the proposed algorithm by conducting extensive simulation studies. The results show that energy can be significantly saved while the overall workload still satisfies the user requirements. |

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.
