A Survey on the Routing Protocols in Vanet

VANET is specialized application of MANET. The need VANET is felt as the number of vehicles are swelling remarkably thereby the traffic density has grown many times. The voluminous traffic density results in more and more accidents. Therefore the manufactures, researchers and Government are forced to improve the on-road safety along-side improving the quality of the roads. As the Wireless technology is improving day by day, various new type of networks, such as Vehicular Ad Hoc Network (VANET) have emerged. VANET is nothing but a communication protocol between Road side Units and vehicles and /or between a vehicle and other near-by vehicle. As the importance of smart cities and labs conceptualized [1] in the recent years where VANETs plays an important role. VANET helps in basic concept of smart cities as it can transmit the traffic information and help driver to drive with safely. An effort is made to provide a survey of various Intelligent Traffic Systems (ITS) and routing protocols. VANET.
