Vehicular Ad-hoc Network (VANET) has emerged as a promising solution for\nenhancing road safety. Routing of messages in VANET is challenging due to\npacket delays arising from high mobility of vehicles, frequently changing\ntopology, and high density of vehicles, leading to frequent route breakages and\npacket losses. Previous researchers have used either mobility in vehicular fog\ncomputing or cloud computing to solve the routing issue, but they suffer from\nlarge packet delays and frequent packet losses. We propose Dynamic Fog for\nConnected Vehicles (DFCV), a fog computing based scheme which dynamically\ncreates, increments and destroys fog nodes depending on the communication\nneeds. The novelty of DFCV lies in providing lower delays and guaranteed\nmessage delivery at high vehicular densities. Simulations were conducted using\nhybrid simulation consisting of ns-2, SUMO, and Cloudsim. Results show that\nDFCV ensures efficient resource utilization, lower packet delays and losses at\nhigh vehicle densities.\n
