| Abstract | We study a network structure for efficient information dissemination that leverages location-based real-time applications operating in a distributed system. Gossip-based information dissemination is a promising method for a large-scale system to keep nodes in the network quickly updated with new information. The information dissemination efficiency depends strongly on the underlying network structure, so it is important to analyze how the network structure is optimized to achieve agile information dissemination, especially for time-sensitive applications, e.g., for dynamic pursuit of a moving target that requires frequent information updating. To this end, we construct a continuous-space network model extended from Kleinberg's small-world model so that it is applicable to location-based services. Analytical and simulation-based study shows that excellent information dissemination efficiency is achieved when the shortcuts overlaying a uniform cluster network are created nearly uniformly to nodes at all distance scales. We apply our model to the dynamic pursuit problem where a pursuer searches for a moving target. Monte-Carlo simulation shows that the network with well-structured shortcuts surpasses other types of networks in finding a moving target because the pursuer can steadily approach the target regardless of its location, and the network structure greatly influences the dynamic search ability in distributed systems. |

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.
