An improved firefly algorithm for the rank generation to optimize the route discovery process in IoV

Vehicular ad hoc networks (VANET) have been the attention gainer for the last couple of years due to increasing number of vehicles on the road. Incorporation of VANET with Internet of Things (IoT) has created large number possibilities in terms of power efficiency and secure transmission. The article focuses on the ad-hoc on-demand distance vector (AODV) protocol and its applications in route discovery in VANETs. In this work, the swarm intelligence (SI) inspired modified firefly algorithm has been employed for rank generation of the nodes. It is concluded that the use of IoT devices and advanced routing protocols with SI algorithms can lead to efficient and low-latency route discovery in VANETs using quality of service (QoS) parameters. The experimental analysis shown that the proposed technique has been outperformed the other existing technique in terms of QoS parameters and provides the optimal route discovery mechanism with high throughput and minimum latency.
