“…Therefore, a number of techniques have been devised to reduce congestion, while maintaining the beaconing effectiveness. The impact of the node density, as well as the beacon frequency and duration, on the performance of an Adaptive Cruise Control application is analyzed in [12], whereas [13] illustrates the degradation of the probability of beacon reception in a large scale urban scenario. An analytcal derivation for the beacon delay and the reception probability is shown in [14] for a scenario where the interval between two consecutive beacon transmissions is not determistic.…”

Multi-hop propagation of situational information is a promising technique for improving beaconing performance and increasing the degree of situational awareness onboard vehicles. A possible way of achieving this is by piggyback information on the beacon packets that are sent periodically by each vehicle in the network, as prescribed by the DSRC and ETSI standards. However, prescribed limitations on beacon size imply that only information about a very small number of surrounding vehicles can be piggybacked in a beacon packet. In most traffic situations, this number is well below the typical number of vehicles within transmission range, implying that multi-hop forwarding strategies must be devised to select which neighboring vehicle's information to include in a transmitted beacon. In this paper, we designed different multi-hop forwarding strategies, and assessed their effectiveness in delivering fresh situational information to surrounding vehicles. Effectiveness is estimated in terms of both information age and probability of experiencing a potentially dangerous situational-awareness blackout. Both metrics are estimated as a function of the hop distance from the transmitting vehicle, and in presence of different level of radio channel congestion. The investigation is based on extensive simulations whose multi-hop communication performance is corroborated by real-world measurements. The results show that network-coding based strategies substantially improve forwarding performance as compared to a randomized strategy, reducing the average information age of up to 60%, and the blackout probability of up to two orders of magnitude.We also consider the effect of multi-hop propagation of situational information on the reliability of a forward collision warning application, and show that network-coding based propagation yields a factor three improvement of reliability with respect to a randomized forwarding strategy, and even higher improvements with respect to the case of no propagation.

“…Van Eenennaam et al [7] verified analytically that the three main dimensions that make the solution space of beaconing in VANETs are transmission power, generation rate and message duration, and showed how different beaconing configurations support Cooperative Adaptive Cruise Control (CACC). Noori et al [8] performed simulations to study the probability of beacon delivery in an urban scenario and showed how packet delivery is impacted by increasing vehicle density and different road types. Kloiber et al [9] analyzed the ability of cooperative message exchange to inform the vehicles about hazardous situations under challenging Medium Access Control (MAC) conditions.…”

We analyze the efficacy of cooperative awareness enabled by periodic message exchange between vehicles and roadside infrastructure. To measure cooperative awareness, we use three metrics: 1) neighborhood awareness ratio; 2) ratio of neighbors above range; and 3) packet delivery rate. Using the measurement data collected within the scope of the DRIVE-C2X project in four European test sites, we analyze the efficacy of cooperative awareness in urban, suburban, and highway environments. Further, we investigate the ability of periodic message exchange to enable cooperative awareness for both Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) links and with different effective transmit power levels. Our results show that: i) the efficacy of cooperative awareness varies greatly in different environments; ii) V2V and V2I communication have distinct awareness and interference patterns; and iii) high awareness levels imply high interference; therefore, a balance needs to be found between them, depending on the context that the vehicles are in.

“…Beacons reliability has been investigated in [13] as a function of different radio propagation models and different vehicular density for the cooperative collision warning application.

Connected vehicles will improve safety and enable new services to drivers and passengers. One of the main enabled services will be the cooperative awareness, that is the broadcast transmission of periodic messages containing updated information on status and movements. This continuos communication may help the drivers in critical situations and eventually enable vehicles to autonomously coordinate their actions. Being IEEE 802.11p still the de-facto standard for vehicle-to-vehicle (V2V) communications, in this paper we investigate its performance for cooperative awareness through large scale simulations involving hundred of nodes under various settings, and considering the combinations of different modulations and coding schemes. Results highlight the effect of traffic density, obstacles, and physical layer settings on both the reception reliability and the delay of information update, giving guidelines for the system design under realistic propagation and road traffic conditions.
