“…For Nakagami m =3, the probability of receiving a packet with a probability greater than 90% occurs when the distance between the transmitter and the receiver is around 0.3 times the transmission range . Therefore, we consider a relay distance of less than 0.3 times the transmission range as low.…”

Intelligent transport systems (ITSs) utilize secure wireless communications to enable vehicle-to-vehicle or vehicle-to-infrastructure connectivity on the road. Single-hop and multihop communications are used to ensure that the vehicles and the infrastructure road side units are notified of current traffic conditions in a timely manner.While security improves network defense against malicious users, it also adds significant computational delay to network transmissions. In particular, for multihop communications, this can result in increased network delays and increased number of retransmissions that cause further network congestions for single-hop safety messages. We present an approach called the fuzzy logic-based adaptive security protocol for multihop (FASPM) traffic to improve the quality of service of ITS applications. FASPM prioritizes the signature verification of ITS messages according to their delay requirements. Moreover, FASPM uses fuzzy adaptation of multihop security levels to reduce network congestion. Simulation results demonstrate that FASPM achieves significant quality-of-service improvements for road safety applications.

Safety message verification plays an important role in securing vehicular ad hoc networks (VANETs). As safety messages are broadcasted several times per second in a highly dense network, message arrival rate can easily exceed the verification rate of safety messages at a vehicle. As a result, an algorithm is needed for selecting and prioritizing relevant messages from received messages to increase the awareness of vehicles in the vicinity. This paper presents the history-based relative-time zone (HRTZ) priority scheme for selecting and verifying relevant received safety messages. HRTZ is an enhanced version of our previously proposed relative-time zone (RTZ) priority scheme. HRTZ achieves higher awareness of nearby vehicles and works in different road configurations. To increase awareness of neighboring vehicles, the average velocity of neighboring vehicles in the range of communication is used to determine the range of the danger zone and other zones. The messages are ranked based on the zone of transmitting vehicles, road configuration (with/without a barrier) and transmitting vehicle location and direction, and relative time between transmitting and receiving vehicles. Only the most up-to-date message from each vehicle is kept in the receiver’s buffer. As a result, each neighboring vehicle has only the most recent safety message in the buffer at any time. The simulation results show that HRTZ achieves a higher rate of verified messages with low delay for nearby vehicles and achieves higher awareness for vehicles in the vicinity, when compared to RTZ and other existing schemes.

“…This metric also has an effect on awareness of vehicles in the vicinity. Inter-Message Delay [ 46 , 47 ]: the delay between two consecutive messages that come from the same transmitting vehicle and are verified at the receiving vehicle. This metric measures whether the verified messages are up-to-date.…”

In high-density road networks, with each vehicle broadcasting multiple messages per second, the arrival rate of safety messages can easily exceed the rate at which digital signatures can be verified. Since not all messages can be verified, algorithms for selecting which messages to verify are required to ensure that each vehicle receives appropriate awareness about neighbouring vehicles. This paper presents a novel scheme to select important safety messages for verification in vehicular ad hoc networks (VANETs). The proposed scheme uses location and direction of the sender, as well as proximity and relative-time between vehicles, to reduce the number of irrelevant messages verified (i.e., messages from vehicles that are unlikely to cause an accident). Compared with other existing schemes, the analysis results show that the proposed scheme can verify messages from nearby vehicles with lower inter-message delay and reduced packet loss and thus provides high level of awareness of the nearby vehicles.
