Location, fundamental information, plays a critical role in many applications and network routings in Vehicular Adhoc NETworks (VANETs). Therefore, it is of importance to validate the location information. We propose a cross-layer design to achieve location validation. We assume vehicles are installed with radar, GPS and transceiver. On physical layer, radar detection can validate GPS coordinates. On network layer, an agreement of a location can be achieved. On application layer, location information as a set of measurements can be filtered and refined by using a proposed data fusion method. We also present results of simulations and evaluate the location validation methods.
