| Abstract | Based on Monte Carlo method, new node localization algorithm is proposed both in rang-based and rang-free conditions. In the range-based Monte Carlo Localization (MCL), the power weight of each particle is given through the distance. Through continuous particles filter updating, the unknown node’s estimated position is obtained. In the MCL range-free algorithm, only one-hop and two-hop anchors are considered. The weight is given by the filter condition. The position of unknown node is confirmed through continuous filtering. An improved DV-Hop algorithm based on Monte Carlo method is also proposed. The simulation results show that these proposed algorithms provide estimates better than existing localization methods such as LS and MLE, reduce calculation complexity, and have high accuracy, robustness, fault tolerance. |

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.
