| Abstract | Constraint of energy is one of the main research challenges in wireless sensor network protocol development. High energy efficiency can be achieved if sensor nodes are organized in to groups to form clusters. In this paper, we propose a new distributed clustering approach in which the set of appropriate cluster heads are elected in each data gathering period upon real time decision made by fuzzy expert system. Fuzzy based cluster head election based on neighbor density and centrality requires either local topology information exchange among nodes or the base station can centrally compute upon reception of information from sensor nodes which naturally consumes significant amount of energy in cluster set up phase. In the proposed protocol, we have defined new approach to estimate level of neighbor density based on mathematical formulations to reduce packet overhead in cluster formation. The fuzzy parameters, residual energy of node and newly defined level of neighbor density put a limit on qualification of nodes to act as cluster heads in the proposed protocol. We have developed fuzzy logic tool on the top of OMNeT++ simulation platform and the performance of the proposed protocol is compared with LEACH and CHEF protocols. A simulation result underpins the superiority of the proposed protocol. |

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.
