Vehicular Ad Hoc Networks (VANETs) are special type of decentralized wireless networks among the various mobile nodes. In VANET decision of forwarding the data packets from one node to other node is dynamic and based on the network connectivity. So efficient, optimized and secure techniques are required for secure transmission of data packets and tracking the changing topology of the network. We propose an ACO based Routing Algorithm in which data packets are forwarded based on the

The nodes exchanges the Ants (agents) between source and destination deposit the pheromone based on the best path between the source and destination. In this proposed scheme we have projected Ant colony algorithm to defense against malicious attack. It also isolates various attacks and provides secure as well as optimize route from source to destination. We have also analyzed the performance metrics such as packet delivery ratio, end-to-end delay, routing overhead and energy consumption. Simulation result shows that our approach is efficient and reliable.
