| Abstract | For various kinds of applications in sensor network, the position information of each sensor tag is essential. Some conventional linear search algorithms used for time-of-arrival (TOA), however, are easily degraded due to serious multipath fading and non-line-of-sight (NLOS) propagation especially in indoor or urban environments. In this paper, we describe some novel algorithms for accurate indoor positioning of a sensor tag in a network of fixed base station. The proposed technique uses node selection method. The proposed algorithm has two position-fix processes. Firstly, the combination of base station in line-of-sight (LOS) environment is selected by locating the base station from the target sensor tag. Then, positioning result is obtained with only combination of base station in LOS environment. Results using simulated data show usefulness of the proposed algorithm which can achieve more robust and precise estimation compared with conventional methods. |

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.
