| Abstract | This paper proposes a novel two-timer-based broadcast routing algorithm for Vehicular Ad-hoc Networks (VANETs), including a new relay selection scheme and a priority queue mechanism to deal with two patterns of safety messages. The new relay selection scheme can not only minimize the number of relay nodes but also improve the packet penetration speed. Two timers are utilized to decide whether the node forwards the received packets. The first timer is used to stabilize the receiving process, and before it expires, the node would update the relative distance to the last sender of the packet. When the first timer is due, the second timer would be activated to ensure that only the furthest receiver from the last sender of the packet would forward the packet. Moreover, a priority queue mechanism is introduced to guarantee the fast spread of time-critical safety messages. The proposed algorithm is totally distributed and relies on GPS information, yet any other prior knowledge such as network topology is not required. Simulation results reveal that our proposed algorithm provides higher efficiency compared with the slotted one-persistence algorithm and the traditional flooding based one. |

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.
