Center node: "location verification systems in emerging wireless networks"
  Abstract: As location-based techniques and applications become ubiquitous in emerging wireless networks, the verification of location information will become of growing importance. This has led in recent years to an explosion of activity related to location verification techniques in wireless networks, with a specific focus on Intelligent Transport Systems (ITS) being evident. Such focus is largely due to the mission-critical nature of vehicle location verification within the ITS scenario. In this work we review recent research in wireless location verification related to the vehicular network scenario. We particularly focus on location verification systems that rely on formal mathematical classification frameworks, showing how many systems are either partially or fully encompassed by such frameworks.
