Vehicular Ad hoc Network (VANET) is a special type of Mobile Ad Hoc Networks (MANETs) where vehicles communicate with the other vehicles or the infrastructure units around using standard protocols. However, deploying VANET applications require intensive labor and high expenses. Usually researchers combined existing mobility simulators with the existing network simulators. Among such hybrid schemes, Vehicle in Network Simulator (Veins) have an increasing popularity. Veins incorporates the widely used Simulation of Urban Mobility (SUMO) with the OMNET++ network simulator. In this paper, we conduct a survey on Veins based studies to explore the recent trends in VANET and provide the current state of VANET standards. We provide novel classifications from different perspectives such as safety, security, routing, traffic management, comfort, and so on. We finally provide recommendations for future research on VANET.
