“…An adaptive strategy which exploits the propagation of beacons received from neighbors is detailed in [21] and in [22]; here, however, forwarding is requested only in potentially dangerous situations or when a beacon loss is detected. In [23], the authors investigate the effectiveness of two opposite strategies for delivering the situational information generated by a vehicle V to a target area: the singlehop strategy, in which V transmits at maximum power and directly reaches all nodes in the target area (up to possible transmission errors); and the multi-hop strategy, in which V uses a lower transmission power, and situational information is piggybacked in a vehicle's beacons.…”

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.

“…On the other hand, rapid changes in traffic density from sparse to heavy, as well as periodic beaconing frequently between vehicles, can cause the wireless channel to promptly become overload and congested, dropping the bandwidth available for the exchange of services' data. Congested links result in a high degree of performance degradation of VANET [2] [3]. The solution to channel overloading does not involve simply reducing the frequency of beacon generation.…”

Abstract. In Vehicular Ad Hoc Network (VANET), rapid movement of vehicles leads to the neighbor information fast outdated. Fast exchange of beacons in high traffic density causes wireless channel congested and overload of VANET. In this article, a Self-Decision-Making Beaconing (SDMB) method is proposed to solve the above issues. In this method, the beaconing interval is adjusted based on node activity and the change rate of its neighbors. Results show that, the successful beaconing rate is closed to or larger than 90% and the normalized channel load is less than 20% in different traffic density by using SDMB.

“…For these simple structure roadside infrastructures, the basic mechanism of the traditional data dissemination strategy is beaconing [15,16]. Beacon packets are periodically and locally broadcasted by a roadside infrastructure to announce its current status and detect whether there are suitable vehicles to disseminate the data to.…”

In vehicular cyber-physical system (VCPS), beaconing mechanism is commonly deployed for the solar-powered roadside infrastructure to detect available passing-by vehicles for data dissemination. The traditional beaconing mechanism would cause a higher energy consumption due to the periodical beaconing procedure. To tackle this problem, we propose a new data dissemination strategy for roadside infrastructures by adjusting the beaconing interval to reduce the energy consumption. We model the beaconing procedure as a Markov model by observing the periodical beaconing results and then using the modeling result to obtain the relationship between the beaconing interval and the expectation of the single-vehicle discovery time. Then, with the average data transmission rate requirement, we can calculate the maximum beaconing interval. We also introduce a satisfaction degree based on the Sigmoid function to combine the decreased energy consumption and the decreased data rate. The satisfaction degree function allows the roadside infrastructure to obtain the optimal beaconing interval based on the required quality of service. The analysis of the results show that careful tuning of key parameters leads to improved energy efficiency and increased data rate of the data dissemination strategy.
