Efficient routing in Vehicular Ad-hoc Networks using firefly optimization

VANETs is used to provide the network environment for intelligent transportation system in which the node speed is very high and topology changes frequently. So that route acquisition and nodes communications in the network are the tedious task. We can't apply the routing protocols of MANETs on VANETs directly. In this paper we describe an approach that is based on firefly algorithm (an implementation of swarm intelligence) to improve the routing performance in the terms of transmission time and better connectivity. The proposed algorithm applies the idea of firefly algorithm on the vehicular ad-hoc network that enhances the performance of routing by efficient packets transfer from source vehicle to destination vehicle.
