Abstract
The present disclosure provides an apparatus mounted on a host vehicle to detect a duplicate temporary ID in basic safety messages (BSMs). The apparatus includes a receiver and a duplicate identifier. The receiver is configured to receive the BSMs from surrounding vehicles through packet transmission. The duplication identifier configured to identify the duplicate temporary ID based on the BSMs having an identical temporary ID value commonly used by at least two surrounding vehicles. A locator is configured to detect a location for each of the packets based on locational information. An absolute distance calculator is configured to calculate an absolute distance between the locations for two successive packets. The duplication identifier is configured to identify the duplicate temporary ID when the absolute distance calculated by the absolute distance calculator is greater than an absolute distance threshold.
