| Abstract | Many applications in VANETs use broadcast communications to disseminate information or keep proper functionality in a network. When the broadcast is multi-hop, it tends to cause unnecessary resource consumption due to the excessive redundant packets on the network, this is known as the broadcast storm problem. Recently, the broadcast storm problem has gained attention due to the impact on VANETs. Many studies emphasize the importance of the forwarding area as a factor for choosing forwarder vehicles. But as important as the use of the area is knowing how many candidates there are to forward a broadcast message. This paper proposes a technique to mitigate that problem through a game theory mechanism: “the volunteer's dilemma”. With this mechanism, the probability of a vehicle forwarding a message is computed, taking into account the cost and the benefit of message propagation. The mechanism's behavior was evaluated by simulations using NS-2. Results showed that when comparing it to a protocol that uses only the area which will be covered as factor for calculating the forwarding probability, packet loss ratio was reduced, as well as latency. |

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.
