Vehicular Ad-hoc Networks (VANETs) represent a rapidly emerging,

particularly challenging class of Mobile Ad Hoc Networks (MANETs). VANET

as a sub class of Mobile Ad hoc Networks (MANET) provides a wireless

communication among vehicles and also vehicle to road side equipment. Nodes

in VANETs are self organized and can self-manage information in a distributed

fashion without a centralized authority or a server dictating the communication

and are thus characterized by very high speed and limited degrees of freedom in

nodes movement patterns. Such particular features often make standard

networking protocols inefficient or unusable in VANETs.They can be used to

establish communication between vehicles and therefore, develop pervasive

VANET tends to operate without infrastructure and each vehicle will be

a node in the network and can send, receive and relay messages with other

nodes. In this way, vehicles can exchange real time information and drivers can

be informed about the road traffic conditions and any other valuable

information. VANETs have attractive unique features distinguishing them from

other types of mobile ad hoc networks like unlimited transmission power,

higher computational capability and predictable mobility.VANET has recently

received considerable attention both from academia and industry. In the past

few years, due to the expansion of wireless communication technologies,

substantial research efforts have been devoted to Vehicle Ad hoc Networks

works (VANETs) for inter-vehicle communications.


 Inter-vehicle communication: Also known as vehicle to-vehicle (V2V)

communication or pure ad hoc. In this case, vehicles communicate with

each other with no infrastructure support and any valuable information

collected from sensors on vehicle can be sent to notify...
