Abstract: Internet of vehicle（IoV）, which is an important foundation of intelligent transportation system（ITS）, is currently a hot research topic. Routing protocol is the core issue of the IoV research. An improved vehicle DTNs（VDTNs）routing algorithm based on multiple forwarding strategy is proposed in this paper, which is used to select a next-hop forwarding node having a higher meeting probability with destination node. We demonstrate in terms of the average transmission delay and arrival rates in our proposed algorithm are better than that of the Epidemic, Spray and Wait, Spray and Focus, and Maxprop protocols through the ONE software simulation.

Key words: internet of vehicle, routing protocol, transmission delay, arrival rate
