| Abstract | Accurate localization and navigation are indispensable for mobile agents to walk in large-scale indoor public space, such as intelligent building and disaster rescue. In this paper, an intelligent localization and navigation system called ISILON is designed and developed. The system consists of a mobile terminal and multiple sensor nodes (also called landmarks) installed in the environment. The mechanism and function of the mobile terminal and the landmarks are same, and they are composed of microprocessor, RFID transceiver, ultrasonic transceiver and related interface circuits. RFID module and ultrasonic module are integrated in each node to provide ID information and range measurement simultaneously. And TDOA (Time Difference of Arrival) between radio frequency and ultrasonic signals is determined to estimate distance between the mobile terminal and the sensor nodes, and trilateration localization technique is applied to achieve accurate position information of the mobile terminal. Moreover, according to the localization result, the mobile terminal can realize path planning, in which an optimal motion path is calculated to guide the terminal to navigate to the given destination. Experiments in a classroom are presented to show the effectiveness of our system. |

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.
