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.
