| Abstract | In multipath-assisted indoor navigation and tracking (MINT), explicit use is made of multipath propagation in the ultra-wideband channel. With the help of floorplan information, localization is possible with only one reference node. In this work, we introduce MINT among cooperating users in order to omit the need of any known reference nodes. The received signal is modeled as a combination of deterministic multipath components, diffuse multipath represented by a random process and AWGN. In a mixed line-of-sight (LOS)/non-LOS (NLOS) indoor scenario, we show how information from mono-static and bi-static measurements of cooperating users can be merged for localization and tracking. The problem is formulated with a factor graph and solved via belief propagation on the factor graph. Simulation results show that localization and tracking of a mobile agent is possible: (i) independent of LOS or NLOS, (ii) without the need for further infrastructure. |

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.
