| Abstract | Wireless Sensor Networks (WSNs) have been broadly studied with advances in ubiquitous computing environment. Because sensor nodes are resource limited, it is important to use energy-efficient routing protocols. The cluster-based routing is an efficient way to decrease transmission traffic and distance, hence, reduce energy consumption. LEACH is a popular cluster-based protocol, which provides distributed adaptive clustering and cluster head (CH) rotation, while LEACH-C is an extension of LEACH, which uses energy to select CH. However, both can't guarantee cluster head distribution in each round, as well as, both have considerable periodic clustering overhead. To resolve such problem, we propose a combined metrics-clustering algorithm based on LEACH-C that adopts a centralized cluster formation and distributed CHs selection method. By using minimum energy clustering, network is divided into energy-balanced clusters, and considering energy and communication distance, optimal CHs are selected in order to prolong network life time. From simulation results the new approach outperforms existing LEACH-C in life time, energy consumption and stability period. |

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.
