DOMAIN - NETWORKSA computer network is a collection of two or more
computers linked together for the purposes of sharing
information, resources, among other things.
These Sharing is done by using Protocols.
A communications protocol defines the formats and
rules for exchanging information via a network.
Networks may be classified according to a wide variety of
characteristics such as medium used to transport the data
What is VANET ?VANET – VEHICULAR AD-HOC NETWORK.
A VANET, is a technology that uses moving cars as nodes in a
network to create a mobile network.
It’s an emerging new technology to integrate the capabilities
of new generation wireless networks to vehicles.
Where the each vehicles are considered as a nodes or router
for communication that occurs approximately 100 to 300
meters.

Applications of VANET
Safety Application
Slow/Stop Vehicle Advisor (SVA).
Emergency electronic brake-light (EEBL)
Post Crash Notification (PCN)
Road Hazard Control Notification (RHCN)
Cont..Convenience Application

Components of VANET enabled vehicle
It include computer controlled devices and
radio transceivers for message exchange.
The Standard protocol DSRC(Dedicated
Short Range Communication), which has a
communication range of 300 mts to 1 km.
The DSRC is performed by using MAC
(Medium access control).
Vehicular CommunicationVANET communicates through Wireless
Access for Vehicular Environments (WAVE).
The WAVE uses different types of Wireless
Commutation devices such as (WiFi / WiMax).
The sensors or wireless devices can form a
VANET network which resides on top of the
vehicle.
Cont.
Communication using FMThe U.S. Federal Communications
Commission (FCC) recently allocated 75 MHz of DSRC spectrum at 5.9 GHz to be used exclusively for V2V and V2R communications.

Future TrendsExpansion of roadway capacity has not kept
up with the growth in travel in the United States, causing significant increases in congestion in major urban areas. Nonrecurring congestion created by crashes or other incidents is a major component of delays experienced by drivers in urban areas.
Most traffic data is currently collected using a network of point detectors, such as inductive loops, microwave radar sensors, or video detection systems.
Cont..DOTs use data for a wide variety of purposes,
including characterizing travel on links, providing real-time monitoring and control, and controlling traffic signals on urban streets.
The type and quantity of traffic data available varies depending on where the data is collected. Major urban freeways tend to have closely spaced sensors that provide real-time data for traffic management.
