A Review of Applications, Characteristics and Challenges in Vehicular Ad Hoc Networks (VANETs)

The density of traffic is increasing daily in the world. As a result, congestion, accidents, and pollution are also increasing. Vehicular ad hoc network VANET, a subclass of mobile ad hoc networks MANETs, is a promising approach for future intelligent transportation system its. These networks have no fixed infrastructure and instead rely on the vehicles themselves to provide network functionality. In this review paper, we present an overview of the concept of vehicular ad hoc networks, applications, characteristics. also, we will provide discuss some of the issues and challenges in VANET.
