| Abstract | People carry smartphones that have a variety of radios and sensors. Increasingly, smartphone applications use the radios and sensors to determine a user's location and to sense motion. Nevertheless, most existing smartphone applications cannot avoid accumulative errors when calculating position and movement. In this paper, we propose a novel approach, Air Loc - Adopting mobile robots to assist indoor Localization of smartphones. A moving robot employs a Bluetooth adapter and a known map to assist a smartphone to reduce its localization error. When a robot is near a smartphone, the robot sends accurate location information to users' smartphones via Bluetooth. We design a path planning strategy for a robot to enhance the localization accuracies of smartphones over extended time periods. Moreover, in order to promote the single robot approach, we extend it to the multi-robot assisted indoor localization. The multi-robots are organized by an unbalanced tree and serve areas by the Distance/Density First Algorithm. Through experimentation and simulation in a multi-room building, we evaluate Air Loc and believe it is promising as a cost-efficient means to yield average positioning error below 0.9 meter and possibly lead to better localization results for some scenarios, including shopping mall and hospital. |

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.
