Abstract: Methods, misbehavior management systems, non-transitory processor-readable media of various embodiments provide for managing the generation, storage, and transmission of misbehavior reports from vehicle-to-everything (V2X) onboard equipment to an associated entity, such as a misbehavior managing authority. Various embodiments may include detecting a misbehavior condition has occurred and determining whether to generate a misbehavior report based on an aggregated criticality value. The misbehavior management system may then determine whether to store the generated misbehavior report. The misbehavior management system may also determine whether to transmit the generated misbehavior report to a misbehavior managing authority. In some embodiments, the misbehavior management system may determine which stored misbehavior reports may be deleted from storage.

Abstract: Aspects relating to abnormal transmission identification include, for example, a method involving, at a receiving device, receiving a plurality of V2X messages from a plurality of transmitting devices, obtaining a plurality of RSSI-to-distance data pairs, including an RSSI-to-distance data pair for each of the plurality of V2X messages, establishing an RSSI-to-distance relationship model based, at least in part, on the plurality of RSSI-to-distance data pairs. The method further involves, at the receiving device, receiving an additional V2X message from a transmitting device different from the plurality of transmitting devices, obtaining an additional RSSI-to-distance data pair for the additional V2X message, and comparing the additional RSSI-to-distance data pair to the RSSI-to-distance relationship model. The method further involves, in response to determining that the additional RSSI-to-distance data pair fails a criterion for conforming to the RSSI-to-distance relationship model, identifying the additional V2X message as an abnormal transmission.

Abstract: Methods, apparatuses, systems, and non-transitory computer-readable medium are disclosed relating to abnormal transmission identification. One method comprises, at a receiving device, receiving a V2X message from a transmitting device. The method further comprises determining a signal propagation context for the receiving device and obtaining an RSSI value and a distance value for the V2X message. The method further comprises generating an adjusted RSSI value based on (1) the RSSI value and (2) the signal propagation context for the receiving device. The method further comprises obtaining a predetermined RSSI-to-distance relationship model and comparing an adjusted RSSI-to-distance data pair, comprising the adjusted RSSI value and the distance value, to the predetermined RSSI-to-distance relationship model. The method further comprises, in response to determining that the adjusted RSSI-to-distance data pair fails a criterion for conforming to the predetermined RSSI-to-distance relationship model, identifying the V2X message as an abnormal transmission.
