| Abstract | Node localization has many applications in wireless networks. For example, it can be used to improve routing and enhance security. Localization algorithms can be classified as range-free or range- based. Range-based algorithms use location metrics such as ToA, TDoA, RSS, and/or AoA to estimate the distance between nodes. Range-free algorithms are based on proximity sensing. Range-based algorithms are more accurate but also more computationally complex. However, in applications such as target tracking, localization accuracy is important. In this paper, we propose a new range-based algorithm which is based on decision tree classification and the density-based spatial clustering of applications with noise (DBSCAN) algorithm, which are well known in data mining. The Euclidean distance between intersection points is used as a distance metric, and the DBSCAN algorithm is applied to a subset of intersection points based on this metric. Different performance measures are used to compare our localization algorithm with linear least squares (LLS) and weighted linear least squares based on singular value decomposition (WLS- SVD). The proposed algorithm is shown to perform better than the LLS and WLS-SVD algorithms even when the anchor geometric distribution about an unlocalized node is poor. |

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.
