The technology which is used to move cars as joint in network to make a transportable network. Participating cars become a wireless connection or router through vanet and it allow the cars almost to connect 100 to 300 meters to each other and in order to create a wide range network, other vehicles and cars are connected to each other so the mobile internet is made. It is supposed that the first networks that will incorporate this technology are fire and police mobiles to interact with one another for security reasons.
Applications of VANET:
Mostly interests to MANETS belong to the VANETS but the features are different. Vehicles are likely to move in structured way. The connection with wayside equipment can similarly be indicated absolutely accurately. In the end, mostly automobiles are limited in their motion range, such as being controlled to pursue a paved way.
VANET suggests unlimited advantage to companies of any size. Vehicles access of fast speed internet which will change the automobiles’ on-board system from an effective widget to necessary productivity equipment, making nearly any internet technology accessible in the car. Thus this network does pretend specific security concerns as one problem is no one can type an email during driving safely. This is not a potential limit of VANET as productivity equipment. It permits the time which has wasted for something in waiting called “dead time”, has turned into the time which is used to achieve tasks called “live time”.
If a traveler downloads his email, he can transform jam traffic into a productive task and read on-board system and read it himself if traffic stuck. One can browse the internet when someone is waiting in car for a relative or friend. If GPS system is integrated it can give us a benefit about traffic related to reports to support the fastest way to work. Finally, it would permit for free, like Skype or Google Talk services within workers, reducing telecommunications charges.
Brilliant way to use Vehicular Networking is defined in VANET or Intelligent Vehicular Ad-Hoc Networking. Multiple ad-hoc networking technologies integrated in VANET such as, ZigBee, IRA, WiMAX IEEE, and WiFi IEEE for convenient, effective, exact, simple and plain communication within automobiles on active mobility. Useful procedures like communication of media within automobiles can be allowed as well process to follow the automotive automobiles are also favored. Security measures are defined in vehicles by VANET, flowing communication within automobiles, edutainment and telemetric.
Selection of wireless technologies are required to implement in VANET as DSRC (Dedicated Short Range Communication) which is include in WiFi. Other entrant technologies of wireless are Satellite, WiMAX, and Cellular. Vehicular Ad-hoc Networks (VANET) can be considered as device of ITS (Intelligent Transportation Systems). ITS (Intelligent Transportation Systems) has conceived vehicular networks. IVC (Inter-Vehicle Communication) permits the automobile communicate to each other at the same time RVC (Roadside-to-Vehicle Communication) allows with the stations based wayside.
The most favorable target is the more useful, efficient and safer roads will built through vehicular networks by informing to basic authorities and drivers in time in the future.Another target is to discover the advancement of vehicular ad hoc networking (VANET) wireless technologies. The purpose is to secure and to make possible commercial requests through range of communication systems and/or other networks (VANET) which goes short to medium. These technologies would support main concern for critical time secure communication and fulfill the QOS needs of other multimedia software or e-commerce mobile. Next goal to create high-presentation, extremely measurable and secured technologies of VANET shows an unusual challenge to the investigate community of wireless. Specific restrictions normally assumed in ad hoc networks are alleviated in VANET yet. Such as, VANET might assemble comparatively huge means of computational.
