Survey on vehicle collision prediction in VANET

Number of vehicles are increasing day by day, adding to the existing traffic and so are the challenges concerning it. Vehicle collision is one of such issues, which needs to be addressed at priority. Many schemes have been put forth recently, to detect vehicle collision probabilities, consequently avoiding collisions and its adverse effects. These schemes in general focus on the issues such as critical response time for alerts, reliable data transfer, efficient broadcasting, security etc. In this paper we have consolidated such recent and niche techniques and its unique features. The survey done provides different approaches for detecting collision and the parameters considered for same. Discussion is also made on various simulators used for simulation thereby providing details of different scenarios and factors involved in VANET.
