| Abstract | Vehicular Ad hoc Networks (VANETs) have gained considerable attention in recent years because of the extensive applications. However, VANETs are confronted with numerous difficulties and challenges, which lead to communication performance degradation and even data delivery failure. In this paper, we propose a new routing protocol called Intersection-based Delay sensitive Routing using Ant colony optimization (IDRA). Firstly, we derive a mathematical delay model for a two-lane road segment. Then based on proposed terminal intersection concept, IDRA makes use of Ant colony optimization (ACO) to find robust and optimal route with min-delay. The forward ants are in charge of exploring routes consisting of a succession of intersections, which are selected considering local road segment delay and global delay from current intersection to the terminal intersection of the destination. The backward ants take charge of collecting global delay and updating ant pheromone along the explored routes. Data packets are forwarded by dynamically choosing the next intersection utilizing updated ant pheromone. Greedy carry-and-forward mechanism is adopted by IDRA to forward data packets between two adjacent intersections, reducing the effects of individual vehicle movement on routing paths. Simulation results validate our derived road segment delay model and also indicate that IDRA shows better communication performance compared with an intersection-based geographical routing protocol (GSR) and a min-delay routing protocol (CAR). |

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.
