| Abstract | Safety applications are currently being developed in next generation vehicular networks to provide road safety. Broadcasting of safety messages unveils the need of reliability assessment since there are no request-to-send (RTS)/clear-to-send (CTS) handshaking and acknowledgment packets in broadcast vehicular communications. Therefore, the reliability of broadcast messages suffer from hidden terminal problem, interference and high mobility. To overcome these challenges, Signal-to-Interference-and-Noise Ratio (SINR) estimation is a key solution so that we can foresee the transmission collisions caused by hidden terminals and prevent its transmissions. Then, we can build a model to improve reliability of broadcast messages. Towards this aim, in this paper, we propose a SINR based hidden terminal estimation model. First, we introduce a method to specify hidden terminals and their transmissions, then we estimate accurate SINR level at the receiver in the near future. Second, we formulate the successfully received packets with a heuristic algorithm and, calculate throughput and hidden terminal radius. Our approach enables significant improvement in the reliability of broadcast vehicular communications. |

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.
