Vehicle-to-vehicle (V2V) technologies open the door for vehicles to share information and interact with each other, as well as with the emerging smart infrastructure. These systems promise not only to make transportation safer and to reduce the environmental impact of automobiles, but also to reduce traffic congestion.

V2V is a communication technology that facilitates crash avoidance. It uses VANETs (vehicular ad hoc networks), which consists of a wireless network whereby vehicles can communicate with one another and share information about their driving behaviors.

The information includes speed, position, braking, stability, the direction of travel, among others. The importance of this technology is to improve the safety of the roads by providing incident alerts before a driver sees or detects them.

V2V communication enables vehicles to transmit data over a wireless mesh network to send, receive, and retransmit signals. A wireless mesh network is one that relies on all nodes to propagate signals. Although the wireless signal may start at a base station (access point) attached to a wired network, a wireless mesh network extends the transmission distance by relaying the signal from one computer to another. Used on the battlefield to provide path diversity, it is also used for sensor networks and personal computers.

These nodes are crucial because they can collect traffic conditions several miles ahead of a driver which is sufficient time for even the unhinged drivers to manage their drives.

In the past, when mesh networks were only wired, this topology was very expensive and difficult to realize, because each node had to be physically connected to the others. Today, by employing the advantages introduced by wireless communications and with the appearance of the Wireless Personal Area Networks (WPANs), these limitations have been overcome.

In these networks, each autonomous and mobile node, connected to the others, forms a graph of arbitrary size (partially connected mesh network). Instead of relying on a base station that coordinates the flow of messages to each entity in the network, the individual nodes forward the packets to each other.

These nodes can move randomly and organize themselves arbitrarily, although wireless topology varies rapidly. Furthermore, these networks can operate alone or be connected to the internet to provide additional services.

This technology employs dedicated short-range communications (DSRC) which is a standard approved by authorities like Federal Communication Commission (FCC) and International Organization for Standardization (ISO).

Under the V2V umbrella, there is the vehicle to infrastructure (V2I) systems that comprise of traffic signals and various stationary devices.
