| Abstract | To reduce energy consumption is an important topic in WSN (wireless sensor networks). One of the popular protocols for energy-efficient WSN is called LEACH (Low-Energy Adaptive Clustering Hierarchy) which is a clustering algorithm designed for homogeneous WSN. Since LEACH selects the cluster heads based on probability, the real and expectance number of cluster heads may be different. However, LEACH is not suitable for heterogeneous WSN because the low-energy nodes can be cluster heads and die quickly. To operate under heterogeneous WSN, several methods are proposed such as SEP (Stable Election Protocol) and DEEC (Distributed Energy-Efficient Clustering). In this paper, we propose a scheme for multi-level heterogeneous WSN. The proposed method is based on the SGCH (Steady Group Clustering Hierarchy). In the proposed method, all nodes are divided into several groups by the initial energy that extends the battery life time and fits for multi-level heterogeneous WSN. Simulations are used to compare the proposed method with previous technologies. We show that the proposed method prolongs the period of stability. |

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.
