| Abstract | Clustering of sensor nodes has been shown to be an effective approach for distributed collaborative information processing in resource constrained wireless sensor networks to keep network traffic local in order to reduce energy dissipation of long-distance transmissions. Defining the range and topology of clusters to reduce energy consumption and retransmissions due to collisions on shared radio channels is an ongoing research topic. One solution is to minimize overlapping cluster ranges to reduce signal contention, thus reducing the energy dissipation of collisions and retransmissions. In this paper, we propose a dynamic cluster formation (DCF) algorithm that dynamically groups a set of sensor nodes into a logical cluster-based sensing and processing unit, collaborative agent sensor team (CAST), to detect and track localized phenomena. Each cluster head is selected locally such that the total overlap between clusters in a CAST is low and the coverage of each cluster head is high. We compare our approach with optimal solutions, and simulation results show the effectiveness and scalability of our CAST DCF algorithm. |

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.
