Internet of Vehicles (IoV)



The Internet of Vehicles (IoV) is a distributed network that supports the use of data created by connected cars and vehicular ad hoc networks (VANETs). An important goal of the IoV is to allow vehicles to communicate in real time with their human drivers, pedestrians, other vehicles, roadside infrastructure and fleet management systems. 

Today, vehicles are increasingly being connected to the Internet of Things which enable them to provide ubiquitous access to information to drivers and passengers while on the move. However, as the number of connected vehicles keeps increasing, new requirements (such as seamless, secure, robust, scalable information exchange among vehicles, humans, and roadside infrastructures) of vehicular networks are emerging. 

The IoV supports five types of network communication:

  • Intra-Vehicle systems that monitor the vehicle's internal performance through On Board Units (OBUs). 
  • Vehicle to Vehicle (V2V) systems that support the wireless exchange of information about the speed and position of surrounding vehicles. 
  • Vehicle to Infrastructure (V2I) systems that support the wireless exchange of information between a vehicle and supporting roadside units (RSUs).  
  • Vehicle to Cloud (V2C) systems that allow the vehicle to access additional information from the internet through application program interfaces (APIs).  
  • Vehicle to Pedestrian (V2P) systems that support awareness for Vulnerable Road Users (VRUs) such as pedestrians and cyclists. 
  • When discussed in the context of 5G and intelligent transport systems (ITS), the five types of networks mentioned above are sometimes referred to as Vehicle to Everything (V2X) communication.
