Vehicular ad hoc networks (VANET) are created by applying the principles of ad hoc mobile networks (MANET) - the spontaneous creation of a wireless network for data exchange - to the vehicle domain. They are a key component of Intelligent Transport Systems (ITS).
Although, in the early 2000s, VANETs were seen as simply applying the MANET principles, they have since become a field of research in their own right. In 2015, the term VANET became the most synonymous with the more generic term of communication between vehicles, although the focus is on the aspect of spontaneous networks and much less on the use of infrastructure such as Road Units ( RSU, or cellular networks.
WORKING
The Ad-Hoc Network, or VANET, is a technology that uses car movements as nodes in a network to create a mobile network. VANET converts each participating car into a wireless router or node, allowing cars from approximately 100 to 300 meters from each other to connect and, in turn, create a network with a wide range. As cars fall outside the range of signals and leave the network, other cars can join, connecting vehicles to each other to create a mobile Internet. It is estimated that the first systems that will integrate this technology are police and fire engines to communicate with each other for security reasons.
VANET offers countless benefits to organizations of any size. High-speed internet access from the automobile would transform the on-board computer from an ingenious gadget's vehicle to an essential productivity tool, making virtually any web technology available in the car. Although a network of this type raises certain security concerns (for example, you can not safely write an email while driving), this does not limit VANET's potential as a productivity tool. It allows "dead time" - the time that is being wasted while waiting for something - to become "living time" - the time that is used to perform tasks. A traveler can turn a traffic jam into a productive work time by having his email downloaded and read to him by the onboard computer, or if traffic stops at a stop, read it himself. While waiting in the car to pick up a friend or relative, one can surf the internet. Even GPS systems can benefit because they can integrate with traffic reports to provide the fastest route to work. Finally, it would allow free VoIP services like GoogleTalk or Skype among employees, which would reduce telecom costs.
