Vehicular Ad hoc Networks (VANETs) are one of the significant areas of research and this is also a subfield in Ad Hoc Networks. This is mainly focused on improving the safety of roads and reducing the total number of accidents. There is no central coordination to this network, nodes are mobile, dynamic topology, the routing process is a big challenge, and this is most responsible for the delivery message to the small overhead and delay. Routing is a tedious task that occurs huge changes in

... rk topology and delivers the data packets in a limited period. In VANETs many existing routing protocols are introduced to overcome various issues but these are not efficient to overcome all the issues in routing. Routing shows a huge impact on other parameters such as data transmission rate (DTR), packet delivery ratio (PDR), Packet Drop Ratio (PDRatio), Average Propagation Delay (APD) and throughput. In this paper, the dynamic and optimized routing approach (DORA) is introduced in VANETs to overcome the various issues and improve the performance of IP by measuring the DTR, PDR and PDRatio. Comparisons among the Ant Colony Optimization (ACO), improved distance-based ant colony optimization routing (IDBACOR), and DORA is shown.
