A Comprehensive Study on Vehicular Ad-hoc Network Routing Protocols

Vehicular Ad-hoc Network (VANET) create all types of vehicle-to-vehicle and vehicle-to-infrastructure communications using radio waves. All the services available in the Vehicular Ad-hoc Network are classified into three different groups, which are safety, traffic control and applications. Safety messages must be exchanged between vehicles to prevent road accidents. Traffic control is used to improve the quality of travel by preventing excessive traffic. Applications are also included in order to create entertainment and services for passengers in the car. In this article, Vehicular Ad-hoc Network (VANET), their applications, challenges and problems are described, and routing protocols in Vehicle Ad-hoc Networks are comprehensively investigated
