“…Given the random-channel-access protocol, the retransmissions which are induced by the collisions further intensifies the collisions. Bi et al 10 proposed a novel composite relaying metric for relaying node selection by jointly considering the geographical locations, physical layer channel conditions, and moving velocities of vehicles. A distributed relay selection scheme based on these composite metrics was designed to guarantee that a unique relay is selected to reliably forward the emergency message in the desired propagation direction.…”

“…8,9 Whereas, distributed relay selection does not require unified control center, and without global information gathering system, each node only needs to collect local network information, thus could elect relay by simple calculation. 10,11 Therefore, a distributed selection scheme can alleviate the burden of a control center and improve the system efficiency greatly, as well as reliability. In VANETs, due to the dynamic network topology characteristic, and that each vehicle has the capability of processing information and completing tasks independently, distributed relay selection is preferred.…”

Data dissemination in vehicular ad hoc networks has been an interesting research topic since rising applications can be run and served based on the success and efficiency of data dissemination in vehicular ad hoc networks. However, the volatile vehicle density, the highly dynamic topologies, and the packet lossy nature of the vehicular wireless communications pose real challenges for vehicular ad hoc networks to achieve high-speed content downloading and efficient resource utilization. In this work, we design a collision-free distributed relay selection method, by jointly considering the geographical locations, channel conditions, moving velocities, and packets receiving statuses of vehicles, to combat the mobility and lossy channel property of vehicular ad hoc networks. Moreover, we adopt the instantly decodable network coding for the selected relay vehicle to retransmit packets which were lost in the original transmission, resulting significant improvements in both network throughput and transmission delay. Simulation results show that the proposed strategy effectively reduces the delay of data dissemination in highway scenarios and improves the downloading rate, as well as the resource utilization of wireless channels.

Efficient message dissemination is of utmost importance to propel the development of useful services and applications in Vehicular ad hoc Networks (VANETs).In this paper, we propose a novel adaptive system that allows each vehicle to automatically adopt the optimal dissemination scheme in order to fit the warning message delivery policy to each specific situation. Our mechanism uses as input parameters the vehicular density and the topological characteristics of the environment where the vehicles are located, in order to decide which dissemination scheme to use. We compare our proposal with respect to two static dissemination schemes (eMDR and NJL), and three adaptive dissemination systems (UV-CAST, FDPD, and DV-CAST). Simulation results demonstrate that our approach significantly improves upon these solutions, being able to support more efficient warning message dissemination in all situations ranging from low densities with complex maps, to high densities in simple scenarios. In particular, RTAD improves existing approaches in terms of percentage of vehicles informed, while significantly reducing the number of messages sent, thus mitigating broadcast storms.

Vehicular networks supporting cooperative driving on the road have attracted much attention due to the plethora of new possibilities they offer to modern Intelligent Transportation Systems. However, research works regarding vehicular networks usually obviate assessing their proposals in scenarios including adverse vehicle densities far from the average values, despite being common in real urban environments. In this paper, we study the effect of these hostile conditions on the performance of different schemes providing warning message dissemination. The goal of these schemes is to maximize message delivery effectiveness, something difficult to achieve in adverse density scenarios. In addition, we propose the Neighbor Store and Forward (NSF) scheme, designed to be used under low density conditions, and the Nearest Junction Located (NJL) scheme, specially developed for high density conditions. Simulation results demonstrate that our proposals are able to outperform existing warning message dissemination schemes in urban environments under adverse vehicle density conditions. In particular, NSF reduces the warning notification time in low vehicle density scenarios, while increasing up to 23.3% the percentage of informed vehicles. As for high vehicle density conditions, NJL is able to inform the same percentage of vehicles than other existing approaches, while reducing the number of messages up to 46.73%.
