| Abstract | We propose a new dispersing protocol for mobile radios equipped with impulse-ultra wideband (IUWB) communication tools. Our network supports communication and ranging between mobile nodes localized at a central base station. The mobile radios are autonomous and make independent decisions based on the information they receive from other radios. Their decision for the direction they move should support their connectivity with other radios, minimize position dilution of precision (PDOP), and increase the covered area. To localize a radio, it needs to be seen by three other radios to have a unique solution for the location of that radio. The proposed protocol has been designed in a way that radios are able to explore and map an unknown floor space. These radios use I-UWB to communicate with each other. The pulsed-transmission nature of I-UWB has many advantages over conventional continuous-wave communication including non-interference, multi-path immunity, and precision through-wall ranging capability. We utilized the non-interfering advantage for re-assessment of pure Aloha scheduling. Through modeling and experimentation we found Aloha is compelling for real-time I-UWB communication and positioning in a mesh of mobile nodes with continually changing network dynamics. The throughput of Aloha for the applied system has been compared with a narrowband 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.
