Vehicular Ad Hoc NETworks versus Internet of Vehicles - A Comparative View

The recent evolution in communication network technologies led to the emergence of a smart connected objects system, which in turn gives the possibility to objects to communicate with each other through Internet of Things (IoT). This last gives to the traditional Vehicular Adhoc NETworks (VANETs) the ability to be extended and have a new naming as Internet of Vehicles (10V). IoV is defined as the real time exchanged information on roads between vehicles and sensors, vehicles and vehicles, vehicles and roads, and also vehicles and personal devices using different wireless communication technologies. Many people confuse between VANETs and IoV and do not know the major differences between them. Several works have been proposed to define VANETs and IoV separately, but no one gives a comprehensive comparison between them. In this paper we clarify the basic differences between VANETs and IoV in different aspects. First we define the difference between VANETs communication architecture and IoV communication architecture. Then we cite the network technologies that exist in VANETs and IoV environments. Next we describe cloud based IoV platform. Finally we illustrate the protocol stack of each system.
