“…And generally, the waiting time of a node is inversely proportional to this distance so the farthest node is elected to be the next relay node. However, Taha et al in [11] introduce a new approach. They assume that the road is divided into adjacent and non-overlapping segments.…”

Abstract-Due to the dramatic increase in the number of accidents all over the world, a rapid emergence of wireless vehicular networks has been perceived in the last few years, particularly, aiming at improving safety and efficiency in the road. Such applications require broadcast communications to disseminate emergency information in brief delay for all the vehicles in the area of danger. Designing an efficient broadcast scheme is crucial. For this reason, a large variety of approaches have been proposed. In this paper, we present a survey on various efforts for designing suitable multi-hop message dissemination schemes for vehicular systems especially which have been focused on reducing channel congestion. Furthermore, we propose a comparison of message dissemination proposals. Their performance evaluation and their advantages and limitations are also highlighted.

“…The safetyoriented applications intend to avoid collision by broadcasting beacons. Taha [21] proposed a novel protocol for reliable broadcasting of life safety messages in VANET. In case of any dramatic change of speed or moving direction, the vehicle is regarded abnormal and hence it transmits an emergency warning message over the control channel of DSRC.…”

Group sensing is a kind of crowdsensing service where HD map producers motivate private cars in a local region to collect data from real world. Group sensing needs vehicles to communicate physically and drivers to collaborate strategically in a mobile or edgeassisted environment. First, we consider collaboration module that motivates drivers to be participants; centralized and distributed motivating methods are discussed. Secondly, we consider communication module; two VANET-based methods are proposed to achieve message relaying in edge infrastructure. To accomplish participants' selection, three combinations of two modules are proposed and simulated based on a flexible framework. The results show that centralized selection could motivate collaboration at a low price but brings heavy communication overhead. Clustered selection requires more incentives and less communication overhead than centralized selection. Distributed selection is usually the first class choice because of its fine performances on both communicating and motivating.

“…Various mechanisms have been proposed to make up for 802.11p for the provision of reliable broadcasts [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In [4][5][6][7][8] the authors proposed extensions of 802.11p to avoid the collisions caused by the hidden terminal.…”

On the other hand [9][10][11][12][13][14][15][16] proposed the acknowledgment schemes for 802.11p to check the reception of broadcast message at the target vehicles and to have the rebroadcast be made if it is needed in order to guarantee the reliable broadcast.…”

“…Differing from [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], [20,21] proposed reliable broadcast mechanisms for VANET to be implemented above the MAC layer, that is, 802.11p. Their common design objectives are to reduce the number of broadcast forwarding attempts by selecting vehicles that can forward the message to the largest possible number of vehicles that have not received the message yet to optimize the broadcast efficiency.…”

A Road Layout Based Broadcast Mechanism for Urban Vehicular Ad Hoc Networks

Safety services of Vehicular Ad Hoc Network (VANET) require reliable broadcasts. We propose a reliable broadcast mechanism for urban roads called VANET Broadcasting for Urban areas based on Road Layout (VBURL), which tries to minimize the dependency on information that may become inaccurate to maximize the efficiency of broadcast. Specifically, the proposed mechanism takes into account the road layout information accessible from the digital map and only the real-time information obtained from the broadcast messages or beacons. VBURL basically makes the vehicle that is farthest from the current forwarding vehicle take the role of next forwarding vehicle and, if possible, makes an additional broadcast happen at the intersections where the effect of signal attenuation caused by the road side obstacles is low in order to have prompt and reliable dissemination of safety messages towards all roads connected to the intersections. The simulation results verified that VBURL achieves the same high performance as that of the compared legacy schemes in terms of reliability with much higher efficiency. Even though the message reception delay of VBURL is slightly longer than those of compared schemes, it is far less significant to impair the original purpose of safety message.
