| Abstract | Warning data dissemination using vehicular networks is envisioned in Intelligent Transportation System applications. Due to extended connectivity of roadway vehicles and consequent extension of region of data propagation, data may be accessed in some geographical areas where it is neither relevant nor effectively beneficial. Moreover, propagating data to irrelevant regions increases communication cost. Therefore it is crucial to limit the warning data dissemination to a certain region. This research strives to address the above challenges by proposing an effective warning data dissemination which restricts data dissemination to a Region of Interest (Rol). Among the factors influencing the Rol determination, the type of warning message is considered so that the more severe the incident, the wider the Rol. Also, in order to reduce message overhead during data dissemination, the strategy which assigns the responsibility of packet retransmission to only certain vehicles (relays) is deployed. In the selection of the relay point, border relay area where the relay point is placed, is adapted to the traffic density so that the higher the traffic density, the narrower the relay area. The proposed scheme informs the vehicles located in the immediate vicinity of an incident, reduces message overhead, and prevents unnecessary and inappropriate message dissemination. |

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.
