Abstract

Vehicular Ad-hoc Network(VANET) is growing field of Intelligent transportation system having the feature of wireless networks. In VANET, communication takes place among Vehicle to Vehicle(V2V) or Vehicle to road-side Infrastructure(V2I). It has the capability to handle traffic condition and reduce road accidents. VANET helps in the dissemination of road conditions and traffic information on moving vehicles. Data dissemination is used for transferring the messages as well as for improving the driving quality in term of distance, time, and safety from source to destination vehicles. In this paper, we discuss the various data dissemination technique and routing protocol used in VANET.
