In the recent years, Vehicular Ad-Hoc Networks (VANETs) have taken a lot of researchers’ attention because it is used in many safety and commercial applications such as safety message dissemination, collision detection, providing comfortable passengers services and traffic control. A vehicular network consists of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications supported by wireless access technologies such as IEEE 802.11p. This innovation in wireless communication has been envisaged to improve road safety and motor traffic efficiency in near future through the development of intelligent transportation system (ITS). At the network layer, the main issue is to invent the energy efficient and reliable routing, to transmit data from source to destination, for maximization of lifetime of the network. In this paper we presents the review in the vehicular ad-hoc network for quality of services such as, communication, delay, packet delivery ration, transmission error etc., also focus on the challenges and issues in the recent trends in vehicular ad-hoc network and discuss the above to resolve in future.
