Recently, Internet becomes an important significant factor of our lives; the dream of a Wi-Fi enabled city is becoming closer and closer to reality. The Vehicular Ad-Hoc Network, or VANET, is a technology that considers moving cars as nodes in a network to create a wireless mobile network. VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 meters of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. VANET offers countless benefits to organizations of any size. Automobile high speed Internet access would transform the vehicle’s on-board computer from a basic service tool to an essential productivity one, making virtually any web technology available in the car. While such a network does pose certain safety concerns (for example, one cannot safely type an email while driving), this does not limit VANET’s potential as a productivity tool. It allows for “dead time”—time that is being wasted while waiting for something—to be transformed into “live time”—time that is being used to accomplish tasks. A commuter can turn a traffic jam into a productive work time by having his email downloaded and read to him by the on-board computer, or if traffic slows to a halt, 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, as they can integrated with traffic reports to provide the fastest route to work. Lastly, it would allow for free, VoIP services such as Google Talk or Skype between employees, lowering telecommunications costs. We intend to use wireless simulation program in our project because it an open source network simulated ensures environment study and analyzes various networks , provide efficient simulator to design VANET (vehicular Adhoc network) , and minimize over head in simulation. Moreover, we are looking to study the VANET performance in many aspects such as, end to end delivery delay ratio, loss probability, stack overflow… Vehicular Ad-hoc Network is one type of network are developed to control traffic, avoid accident and to reduce unwanted defects occurred by traffic network. Nowadays, various new vehicles are developed with more features and methodology which is completely achieved by a VANET projects.
