“…suppression schemes are implemented to forward the broadcast message; otherwise, one of the neighboring nodes broadcasts message in the opposite direction of the traffic flow. In [22], by considering the presence of the intersections, a bandwidthefficient technique for information dissemination in urban scenarios in VANETs is proposed. For identifying intersection it has used two different techniques: digital map and the calculation of the message reception angle.…”

“…The aim of this method is trying to reach the neighbors that may be hidden around the corners of sender nodes. However, the protocols presented in [21] and [22] have not used the adaptive strategy to broadcast beacon messages. In our paper, considering the VANETs characteristics such as vehicle speed, distance, and direction, an "adaptive beacon broadcast in opportunistic routing" strategy for the non-safety applications is presented.…”

“…This ensures that the exact positional information of the nodes in the data forwarding path is maintained. The proposed method similar to [21] and [22] is classified as a multi-hop broadcasting routing protocol. However, in these two methods ( [21] and [22]) the adaptive beaconing mechanism or positional estimation model, are not considered.…”

“…Moreover, to illustrate the effect of the positional estimation mechanism on the routing function, the method is implemented on the LSA protocol presented in [12], which has used the parameters of stability and advancement which depend on the position of the vehicles. In addition, the proposed method in the second group of simulations is compared with multi-hop broadcasting routing protocols of DV-CAST [21] and method in [22]. The DV-CAST protocol is used the broadcast suppression schemes and employs store and carry forward mechanism in different modes.…”

Broadcast of beacon messages including geographic coordinates, node speeds, and directions are among the most commonly used methods in routing protocols of VANETs to obtain neighboring positions. Broadcast of periodic beacon messages in fixed time intervals will reduce network performance due to increased channel load and contention. In this paper, an adaptive update strategy for sending beacon messages according to the VANETs' characteristics (position, speed, and direction) and the nature of broadcast wireless channel in an opportunistic routing strategy is studied. It is based on two rules: 1) an estimation of the lifetime of the links between vehicles' beacon messages are sent after the expiration of the estimated time to inform their local topology and 2) if the forwarding set of consecutively received data packets is changed, a beacon message is sent to maintain the accuracy of the topology. The simulation results show that the proposed strategy significantly reduces the cost of routing and improves network performance in terms of packet-delivery ratios, average end-to-end delay, and routing overhead.

Abstract:The recent release of standards for vehicular communications will hasten the development of smart cities in the following years. Many applications for vehicular networks, such as blocked road warnings or advertising, will require multi-hop dissemination of information to all vehicles in a region of interest. However, these networks present special features and difficulties that may require special measures. The dissemination of information may cause broadcast storms. Urban scenarios are especially sensitive to broadcast storms because of the high density of vehicles in downtown areas. They also present numerous crossroads and signal blocking due to buildings, which make dissemination more difficult than in open, almost straight interurban roadways. In this article, we discuss several options to avoid the broadcast storm problem while trying to achieve the maximum coverage of the region of interest. Specifically, we evaluate through simulations different ways to detect and take advantage of intersections and a strategy based on store-carry-forward to overcome short disconnections between groups of vehicles. Our conclusions are varied, and we propose two different solutions, depending on the requirements of the application.
