Paper Title
Global positioning system forensics in vehicular Ad-hoc networks

Global Positioning Systems (GPS) have become more affordable and are now widely used in motor vehicles and in other frequently used applications. The principal purpose of vehicle tracking systems is generally to provide real-time information for efficient traffic control; they also serve an important security function along with enabling vehicles to alert each other with information like speed, position, acceleration and road conditions over short and medium range wireless networks called Vehicular Ad Hoc Network (VANET). By continuously displaying up-to-date location information and identifying vehicles that deviate from planned routes or cross specific boundaries, the GPS devices help protect assets that include the vehicles themselves and their high-value contents. As a consequence GPS are increasingly becoming an important source of evidential data for digital forensic investigations. The aim of this paper is to provide the guideline of recovering forensic data from widely used GPS devices. These devices are in-car navigators, Smart Phones, Digital Cameras, and so on. Evidentiary data can be gleaned from these devices to allow the recreation and tracing of the path taken before, during, and after a crime.
