“…To overcome the impact of jamming, an approach of message and channel redundancy has been demonstrated in [7] for the case of constant, random and intelligent jamming. This approach implies using alternative messages, namely the À la Carte (ACM) and Probe Vehicle Data (PVD) to deliver safety related data using redundant channels.…”

“…Consequently, the application fails only if no BSM message is received before t_react. The unreliability 〖Q(t)〗_(app =1-〖R(t)〗_app ) i.e., the probability of not receiving any BSM_i, i = 1... X, can be expressed as: (ti) x i=1 (7) Where 𝑄 𝑖 is the probability that BSM_i was not received at t_i. It should be noted that 𝑄 𝑖(𝑡 𝑖) is the packet error probability of BSM i .…”

Intelligent Transportation Systems (ITS) encompasses technologies, services, and applications facilitating communication between vehicles (V2V) and between vehicles and fixed infrastructure (V2I and I2V). This mutual interaction constitutes a Vehicular Ad-Hoc Network (VANET) which supports a plethora of applications targeting critical transportation aspects, such as safety, mo-bility, and environmental considerations. Dedicated Short Range Communications (DSRC), op-erating on the 5.9 GHz band, is pivotal for such exchanges. We introduced an innovative algorithm designed to identify jamming attacks and transition the Safety Application to a secure fail-safe mode. This algorithm leverages a dual-metric strategy, incorporating both distance and PDR measurements. Field tests confirm that our algorithm adeptly recognizes the activities of deceptive jammers, ensuring a prompt shift of the safety application into its fail-safe state. This paper delves into these countermeasures, evaluating their efficiency via mathematical modelling, simulations, and on-ground testing. Findings acknowledge that these strategies bolster the reliability of safety applications in jamming scenarios. Furthermore, the approaches propounded align with ongoing standardization endeavours by relevant authorities, ensuring communication mediums remain unhindered.
