Simulation Environment for VANET

Abstract: Vehicular Ad hoc Networks (VANETs) are classified as an application of Mobile Ad-hoc Networks (MANETs) that has the potential in improving road safety and providing Intelligent Transportation System (ITS). But VANET simulation is different from MANETs (mobile ad hoc networks) simulation because in VANETs vehicular environment imposes new issues and requirements, such as constrained road topology, multi-path fading and roadside obstacles, traffic flow models, trip models, varying vehicular speed and mobility, traffic lights, traffic congestion and driver�s behavior. There are different type of simulators that we have used. These simulators are traffic simulators network simulators and combination of both VANET simulator. In this paper, we have studied different type of simulators and their software characteristics, graphical user interface, accuracy of simulation, input requirement output visualization
