“…Data exchange in V2V communications systems faces many challenges, such as high mobility and intermittent connectivity between vehicles due to changing their velocity and direction constantly and unpredictable network topology [12], [15], [16], [46], [51], [79], [104], [110], moving in opposite direction [79], amount of time needed to establish connection links with other vehicles [95] and high speed, which require fast data transmission [31], [80], [113], [118]. Stochastic V2V communication with frequent information exchange, low latency and high reliability among vehicles poses a great challenge on communication systems [1], [55], [78], [82], [117], [119], [138], packet loss and transmission delay [97], [121] and transmission range degradation [14] when supporting real-time services due to deep fading and co-channel interference [122].…”

Data exchange in Vehicle-to-vehicle (V2V) communications systems is a field that requires automated solutions, tools and methods and the capability to facilitate early detection and even a prediction. Many studies have focused on V2V system and its classification to improve road safety, reduce traffic congestion and help streamline the vehicle flow on the road. This study aims to review and analyse literature related to data exchange in V2V communications systems. The factors considered to improve the understanding of the field's various contextual aspects were derived from published studies. We systematically searched all articles about the classification and detection of data exchange in vehicles, as well as their evaluation. Three main databases, namely, ScienceDirect, Web of Science and IEEE Xplore from 2008 to 2018, were used. These indices were considered sufficiently extensive to encompass our literature. On the basis of our inclusion and exclusion criteria, 140 articles were selected. Most articles (53/140) are studies conducted in a V2V communication system; a number of papers (51/140) covered the actual attempts to develop V2V communications; and few papers (18/140) comprised framework proposals and architectures. The last portion (18/140) of articles presented review and survey articles. V2V collision avoidance system, which is a field requiring automated solutions, tools and methods, entails the capability to facilitate early detection. Several studies have been performed on the automatic detection of V2V and their subtypes to promote accurate detection. The basic characteristics of this emerging field are identified from the aspects of motivations, open challenges that impede the technology's utility, authors' recommendations and substantial analysis of the previous studies are discussed based on seven aspect (devices, number of scenario, test location, types of sensors, number of vehicle, evaluation techniques used and types of software). A propose research methodology as new direction is provided to solve the gaps identified in the analysis. This methodology consists of four phases; investigation, develop a hardware system, study and analysis, and evaluation phases. However, research areas on V2V communication with the scope of data exchange are varied. This systematic review is expected to open opportunities for researchers and encourage them to work on the identified gaps.

“…Examples of this type of protocols include: Local Routing Algorithm (LRA) [11], Traffic Flow-Oriented Routing pro-tocol for VANETs (TFOR) [13], Vehicle Density and Load Aware routing (VDLA) [3], and intersection-based Connectivity Aware Routing (iCAR) [29].…”

“…the vehicular traffic density resulted from the current available number of moving nodes on the road segments) for maintaining their connectivity, where even some researchers such as [7] have listed them under the category of traffic-aware routing. For example, protocols such as A-STAR [8], VNIBR [9], RIVER [10], and JMSR [4] depend on traffic density as the only metric for evaluating and selecting the best routing path in terms of connectivity, while other protocols such as LRA [11], BAHG [12], TFOR [13], and GyTAR [14] exploit more than one metric for selecting the sequence of junctions that represents the best routing path; however, even in such protocols, the dependency on traffic density is still clear as density is still one of the selection metrics. Moreover, an in-depth analysis done by [1,15,16] showed that most of junctionbased protocols depend on the current existing traffic density for maintaining their connectivity, where they assume either a high or an even traffic density in the road segments.…”

In this work, a new routing protocol designed exclusively for improving the connectivity of junction-based routing in city scenarios of vehicular ad hoc networks is introduced. The main objective of this protocol is eliminating the dependency of routing paths construction's process on the current available traffic density inside the road segments. To do so, the proposed CJBR protocol employs a multi-metric junction selection mechanism which depends on several metrics to select the best candidate junction to be the next data forwarder. The novelty of CJBR is represented by exploiting an enhanced group of the current road light poles in each road segment as a junction selection metric. Simulation results have shown an improvement in the packet delivery ratio and delay of CJBR compared to other junction-based protocols.

“…In particular, the work by Saleet et al [28] considers road layouts with intersections for routing. Later, Acarman et al [29] showed how message routing can also be done by selecting intersections as points of relay using commercial navigation map data and having the connectivity information of road IDs. Similarly, other research works like [30] take advantage of intersections for forwarding messages.…”

Event warnings are critical in the context of ITS, being dependent on reliable and low-delay delivery of messages to nearby vehicles. One of the main challenges to address in this context is intersection management. Since buildings will severely hinder signals in the 5 GHz band, it becomes necessary to transmit at the exact moment a vehicle is at the center of an intersection to maximize delivery chances. However, GPS inaccuracy, among other problems, complicates the achievement of this goal. In this paper we study this problem by first analyzing different intersection types, studying the vehicular communications performance in each type of intersection through real scenario experiments. Obtained results show that intersection-related communications depend on the distances to the intersection and line-of-sight (LOS) conditions. Also, depending on the physical characteristics of intersections, the presented blockages introduce different degrees of hampering to message delivery. Based on the modeling of the different intersection types, we then study the expected success ratio when notifying events at intersections. In general, we find that effective propagation of messages at intersections is possible, even in urban canyons and despite GPS errors, as long as rooftop antennas are used to compensate for poor communication conditions.
