“…We only consider unidirectional traffic flow. Using bidirectional traffic in VANET communication can increase connectivity [29][30][31], but requires more complicated store-carry-forward routing strategy, and causing long message delivery delays [31][32][33][34]. The VANET is connected if X i is less than the communication range z, for all values of i.…”

“…In Segcast, we assign an agent to perform multiple times of store-carryforwarder over a road segment. Instead of the conventional SCF that broadcasts the message when a forwarder first meets a new vehicle, our method employs the same idea used in the previous work, Store-Carry-Broadcast (SCB) [7], that only broadcasts when the forwarder finds that the broadcast transmission can cover the largest set of receiving vehicles. Then this task repeats several times until all vehicles along the intended road segment receive the message.…”

“…State-of-theart schemes [3], [4], [5], [6] have adopted the Store-CarryForward (SCF) based schemes to utilize a moving vehicle to bridge the communication gap between two disconnected vehicles on reverse lane. In [7], the SCB scheme uses an opposite vehicle to disseminate the safety messages to oncoming vehicles traveling on the reverse lane with the check of further disconnected clusters.…”

This paper investigates the network performance for information dissemination via broadcasting in Vehicular Ad Hoc Networks (VANETs). The major challenge of broadcasting is to disseminate messages over the intended regions with low cost while to ensure the reliability of message delivery. To minimize the broadcast cost in delay tolerant data dissemination, this paper proposes a method, called Segcast, along with an analytical model to easily compute the broadcast cost and end-to-end delay according to the input parameters describing the network environment, such as the vehicular density and the transmission range. In this method, an appointed vehicle, named Segcast agent, is selected to transmit a broadcast message to oncoming disconnected vehicles located on a given road segment. Compared with the state-of-the-art approach, Segcast consumes much less network bandwidth and significantly improves the survivability of the message dissemination in large areas that have intermittent connectivity. Simulation results are presented to demonstrate that Segcast can perform efficient broadcasting for delay tolerant applications.

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%.
