Abstract
VANET, short for Vehicle Ad-hoc Network, is an emerging technology with unique characteristics that differentiate it from previous ad-hoc networks. Designing an effective routing protocol for V2V (vehicle-to-vehicle) communication and V2I (vehicle-to-roadside infrastructure) communication is particularly challenging due to the dynamic nature of topology and frequent disconnections. VANET plays a crucial role in the development of Intelligent Transportation Systems (ITS) aimed at enhancing traffic flow and safety, primarily due to the high occurrence of traffic accidents. However, existing VANET routing protocols face limitations in effectively handling diverse traffic scenarios. To ensure future communication between vehicles for road safety, it is essential to develop appropriate routing protocols. This paper focuses on analyzing the advantages and disadvantages of routing protocols that can contribute to the development of new or improved routing protocols in the near future.
