Intelligent Decision Based Route Selection and Maintenance Approach Using AOMDV in VANET

Abstract: Vehicle Ad Hoc Network (VANET) is a dynamic network with a variety of applications in intelligent transport systems. There are several routing protocols for establishing paths between sending and receiving nodes. AODV is a reactive routing protocol that broadcasts a route request to all adjacent nodes, which forward the request to their neighbors. This process helps select the path from sender to receiver. The AODV protocol is the best routing protocol when you have a large number of communicating nodes. In this study, AODV and Ant Colony Optimization (ACO) techniques are applied to transfer data. Ant colony optimization algorithm is applied considering the initial coordinates of each node. Paths established using reactive routing protocols are likely to congest the network and also consume large amounts of network bandwidth. This research is based on using a multicast approach to establish a path from source to destination to reduce the potential for network congestion. It generates the shortest route and achieves higher throughput, less packet loss, and less delay than existing protocols.
