Vehicle-to-vehicle communication is an automotive technology which allows automobiles to “talk” to each other. V2V communications form a wireless network on the roads by connecting with each other. These networks are also called as vehicular ad hoc networks, VANETs. The systems will use the unlicensed frequency region of the 5.9 GHz band set aside by the United States Congress,  also used by WiFi. The US V2V standard, commonly known as WAVE (“Wireless Access for Vehicular Environments”)

A careful study of the road accidents taking place all over the world has revealed that majority of them take place because the action taken by the vehicle ahead is not understood clearly by the following vehicle. Hence in exigency, the driver of the following vehicle fails to take an action that is complementary to the one taken by the front vehicle. If the actions of the vehicle travelling ahead could be communicated clearly to the following vehicle, will be helpful in avoiding such accidents. To achieve this purpose, vehicle to vehicle (V2V) communication system is developed.

An extension of V2V is V2X (Vehicle to Everything). Cars will talk to other, exchanging data with each other and alerting drivers to potential collisions. They’ll talk to sensors on signs on stoplights, bus stops, even ones embedded in the roads to get traffic updates and rerouting alerts. And they can communicate with your house or office, and smart devices or will  act as digital assistant, gathering information you need to go about your day.

Your car can route your travel, or reroute it when you’re on traffic or when you get behind schedule, when you are just getting ready for your office. It can give you an update from your calendar of your schedule.

Automobiles today have an impressive amount of processing power. More than 100 million lines of software code help run the typical luxury vehicle. The amount of information flowing, back and forth from them will skyrocket. And so this will demand for the cloud’s scaleability of storage capabilities.

The cloud also provides sophisticated processing and analytical capabilities. And the cloud is also the home for building and developing the apps and programs used by cars on the road.

This will help cities and states cut down on congestion and improve safety. Cars will automatically transmit data such as position, direction, and speed, and will send alerts to each other if a crash seems possible. This future of vehicle-to-vehicle, or V2V communication, is already in the works, with the U.S. Department of Transportation announcing early this year that it plans to start taking steps to enable V2V communication.

Limitations of V2V:

Threat of hacking: Being IT dependent system, they are vulnerable to attacks of hacking or cracking. In such a situation, the hacker can alter the information being displayed in the vehicle thereby causing a disaster.

Additional cost: It is estimated that the cost of installing vehicle to vehicle communication system would be in the range of 1800 USD to 21000 USD depending upon the vehicle model and complexity of the system.

The frequency band set aside for this system can’t support a large number of vehicles simultaneously.

 

As of this writing it is unclear till now whether creation and maintenance of the supporting network would be publicly or privately funded. Automotive manufacturers working on ITS and V2V include GM, BMW, Audi, Daimler and Volvo.

V2V communication provides opportunities as well as challenges for the industries. We can expect to experience a fully mature V2V communication system till 2020.
