Intersection-based routing on top of a virtualization layer to support vehicular cloud applications in a smart city

The development of the smart cities is strongly linked to the Internet of Things (IoTs), where a lot of quotidian objects with connection capabilities interact in many applications over the network. One of the more relevant branches of the IoTs is the Internet of Vehicles (IoV), the next step in the Vehicular Ad hoc Networks (VANETS) as the number of vehicles connected to the IoTs increases. The main purpose of IoV is to combine the resources of many vehicles, things and networks to provide a robust communication capability. In this context the Vehicular Cloud applications take a great importance harnessing the wealthy resources contributed by groups of vehicles to enable innovative information services on the road. In this paper we present the architecture and the main procedures of a Vehicular Cloud Computing model on top of a virtualization layer and evaluate the adequacy to some Vehicular Cloud applications of special interest in smart cities of three different flavors of a new algorithm called VNIBR (Intersection-Based Routing on Virtual Nodes): reactive, proactive and encounter-based.
