| Abstract | In this paper, we present CENTER, a CENtralized Trust-based Efficient Routing protocol for wireless sensor networks (WSN). CENTER is a secure and efficient routing protocol that utilizes the powerful sink base station (BS) to identify and ban different types of misbehaving nodes that may interrupt or abuse the functionality of the WSN. In CENTER, the BS periodically accumulates simple local observations of every node and deduces a detailed global view of the network. The BS calculates different quality metrics - namely the maliciousness, cooperation, and compatibility, approximates the battery life, and evaluates the Data Trust and Forwarding Trust values of each node. The BS then uses an effective technique to isolate all “bad” nodes, whether misbehaving or malicious, based on their history. Finally, the BS uses an efficient method to disseminate updated routing information, indicating the uplinks and the next hop downlink for every node. Through its centralized approach, CENTER provides more efficient and secure routing while accounting for the energy-constrained sensor nodes. We present simulation results of CENTER performed using TOSSIM to verify its correctness, security, and reliability. |

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.
