| Abstract | IEEE 802.11p provides a communication standard for Wireless Access in Vehicular Environment (WAVE), including both safety and non-safety communications. Safety-related communications can be from either event-driven or periodic-driven requests. The event-driven messages usually convey emergency information and, hence, are more critical than periodic-driven messages. IEEE 1609.3 specifies the operations under WAVE to provide network services and defines Wave Short Message Protocol (WSMP) for safety-related packets delivery. However, WSMP lacks a congestion control mechanism to avoid from packet lost. In this paper, we apply WSMP for communication among vehicles as well as the road site units (RSUs), and provide a discard-based congestion control scheme at RSU to mitigate the congestion problem. A Markov-chain model is also presented to compute the dropping probability and expected delay of safety-related packets. Numerical results show that the dropping probability of event-driven packets can be effectively controlled with the offset of discarding the periodic-driven packets using a threshold setting. Inter-relationship between traffic load and the value of threshold is also investigated. |

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.
