| Abstract | This paper introduces VeMAC, a novel multichannel TDMA MAC protocol designed specifically for a vehicular ad hoc network. The network has one control channel and multiple service channels. On the control channel nodes acquire time slots in a distributed way, while on the service channels nodes are assigned time slots in a centralized manner. VeMAC decreases the probability of transmission collisions caused by node mobility by assigning disjoint sets of time slots to vehicles moving in opposite directions and to road side units. Analysis and simulation results are presented to demonstrate the efficiency of VeMAC and compare it to ADHOC MAC, an existing MAC protocol based on TDMA. It is shown that, for the same number of contending nodes and available time slots, nodes can acquire time slots on the control channel much faster in VeMAC than in ADHOC MAC, when the number of available time slots is sufficiently larger than the number of contending nodes. |

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.
