VEHICULAR AD HOC NETWORKS
Vehicular ad hoc network is one of the most interesting research areas due to low cost, flexibility, fault tolerance, high sensing fidelity, creating many new and exciting application areas for remote sensing. So, it has emerged as a promising tool for monitoring the physical world with wireless sensor that can sense, process and communicate. Their applications range from safety and crash avoidance to Internet access and multimedia. VANETs are considered as one of the ad hoc network real-life application enabling communications among nearby vehicles as well as between vehicles and nearby fixed equipment, usually described as roadside equipment. In this paper, we are most concerned about the study of VANET applications as it is an evolving field which offers scope for research.
