Vehicular networking serves as one of the most important enabling technologies required to implement applications related to vehicles, vehicle traffic, drivers, passengers and pedestrians. Intelligent Transportation Systems (ITS) that aim to streamline the operation of vehicles, manage vehicle traffic, assist drivers with safety and other information, along with provisioning of convenience applications for passengers. There has been significant interest progress in the field of vehicular networks over last years. Vehicular network is a unique area of wireless communication. In this paper, the authors provide a survey of the state-of-the art of vehicular network and provide an overview of the characteristics of vehicular networks, their applications, their requirements and their challenges.
