Abstract | Energy efficiency is one of the most important issues of wireless sensor networks (WSN). The routing technology of the network layer is critical in reduce the energy consumption in WSN. Nevertheless, the reliability and data aggression also should be analyzed. To solve these issues, an energy effective routing protocol based on low-energy adaptive clustering hierarchy algorithm is proposed to meet those key Qos requirements. The proposed protocol focuses on some defects of the traditional LEACH, and improves the energy efficiency and other QoS parameters by excluding the node with improper geographic location to be the cluster heads. In the protocol, the optimum measuring range of head nodes is designed to be a criterion of cluster head selection, and every cluster heads can be selected according to the node density threshold in the measuring area, which is confirmed by the node distribution situation and communication requirement. With the simulations, the proposed protocol is evaluated in comparison with the traditional LEACH algorithm. The performance of the proposed protocol is verified to not only reduce the energy consumption but also guarantees the communication quality especially in the uneven distribution situation. |

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.
