Abstract: Abstract The Vehicular Ad-hoc Networks includes high-density vehicles, communication access points, data collection and traffic load management. The nodes of these networks are relatively fast, thus accurate data transfer is a major challenge over time. As a result, routing in such networks can be taken as serious issue. To overcome this, an Optimal Geographic Cluster-based Scheduled Routing (OGCSR) protocol for VANET is proposed. It is divided into three stages, first, a multi-hop cluster formation is done using the Improved Chaotic Ant Swarm optimization method. Second, Cluster Head selection by measuring the optimal cluster member and third, searching for the nearby neighbours with Adaptive Neighbour Search algorithm and initiate data scheduling process to reduce the extra time of transmission of control packets. Finally, the performance of OGCSR is evaluated and compared with Cluster Based Life Time Routing, AODV for Conectivity in Vanet and Cluster Based Directional Routing Protocol protocols. As per the results analysis, with a constant speed of 40 kmph, the proposed routing protocol OGCSR gives 13.1% increase in packet delivery rate, 3.5% less delay and better throughput in a high density network.
