摘要：Tachographs are used in vehicles for keeping track of driver’s hours and for other purposes of fraud detection, overspeeding and accident investigation.Their usage and benefits are in danger beacuse of increasing levels of frauds and manipulation.Tachograph fraud and tampering has become very common due to which the driver‘s hours and speed regulation are spurned on a large level.Most of these frauds are stimulated by economic pressure on vehicle operators and can be reduced if improved tachograph systems are introduced.Tachographs are used in vehicular environments.Vehicular communication networking is a promising approach to facilitate traffic mangement, road safety and infotainment dissemination for drivers and passengers.With the advancements in vehicular ad hoc networks, transporation safety and efficiency are at stake. Due to this fact, the security, privacy and protection of a private user have became rudimental part of the deployment of technology.The flaws in security of vehicular ad hoc networks can be exploited by even common users, who can interrupt or disable it if some strong and practical security enhancing features are not applied.In this paper we are proposing a new network for vehicular communications based on improved tachographs.The advance features in the tachographs can be helpful in the security and wireless communication vehicular Ad hoc networks.
