Abstract
Vehicular ad hoc network is one of the most interesting research areas due to flexibility, low cost, high sensing fidelity, fault tolerance, 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. Being ad-hoc in nature, VANET is a type of networks that is created from the concept of establishing a network of cars for a specific need or situation. VANETs have now been established as reliable networks that vehicles use for communication purpose on highways or urban environments. VANET considered as a distinct type of Mobile Ad Hoc Networks holds the opportunity to make people's life and death decisions by predicting and helping the drivers and other people about the road safety and other critical conditions. This paper outlines the VANET definition, its architecture and protocols from a research point of view and future research directions of VANET are provided in the end of paper.
