| Abstract | We introduce an analytical framework for quantitative safety level evaluation of periodic-based safety applications in vehicular ad hoc networks (VANETs). The framework is based on Markov chain modeling and associates the probability of successful reception of safety messages by the safety application with the safety level which is eventually offered to the passengers. The relationship between distance and safety risk is also incorporated in the proposed model. The idea of this paper challenges the common trend in literature in which quality of safety (pertaining to safety application) is evaluated through the same parameters as quality of service (of the network). Based on the proposed framework, we investigate the effects of vehicles' transmission range on the evaluated safety level. Further we showed that despite of poor performance of the MAC layer of current standard, which is based on IEEE 802.11p, invoking application layer TDMA-like scheduling improves the quality of safety noticeably satisfying the requirements of most of the life safety applications. |

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.
