Intelligent Transportation System (ITS) applications for integral and cooperative vehicle safety as well as some Advanced Driver Assistance Systems (ADASs) benefit from precise determination of relative positions between dynamic traffic objects. With conventional Global Navigation Satellite System (GNSS) measurements, e.g. using Global Positioning System (GPS), the required accuracy cannot be achieved...
Car2X communication is about to enter the mass market in upcoming years. So far all realization proposals heavily depend on the global positioning system for providing location information and time synchronization. However, studies on security impact of this kind of data input have focused on the possibility to spoof location information. In contrast, attacks on time synchronization have not received...
In Intelligent Transport System (ITS) there is a new kind of ad hoc network: Vehicular Ad-hoc Networks (VANET). In VANET, vehicles get useful information by communicating with each other or with a roadside unit. The location information is important in VANET. It is easy to obtain the locations of vehicle by GPS technology. However, there still are some unexpected problems such as not always being...
Acquiring and securing position information is of fundamental importance in vehicular ad hoc networks and their applications. Recently, it has been shown that securing position information can be achieved by enlisting the help of on-board radar devices that have seen a phenomenal penetration of the vehicular market. However, most on-board radar devices have a static range and this can cause a number...
