“…Basically, the vehicle direction toward the destination with high vehicle density is projected for routing and is considered to be a favorable metrics. However, without vehicle direction, the route with the same vehicle density but in two directions has higher breakage probability [30]. DECA only uses vehicle density and suffers more from this issue compared to the DAR-RH, ARP-QD, and real-time protocols.…”

“…Therefore, only using the vehicular density measurement is not suitable without vehicular spatial distribution in the network. Taking vehicle density with direction metrics into account will lead to better performance and lower connection breakage probability compared to routes with the same density, as stated in [30]. Some RAR protocols, such as VLBR and iCARII, utilize statistical density.…”

The tremendous advancement in new wireless technologies has led to a renewed interest in vehicular ad hoc networks. However, due to the high mobility and dynamic nature of vehicular networks, great challenges exist for data delivery. In order to design efficient and smart routing strategies for stable communication, several different types of routing protocols have been integrated. One efficient type is the road-aware routing protocol which is based on road statistics (e.g., traffic density, intersections, and road segments). The main objective of the survey conducted in this paper is to discuss the recent road-aware routing protocols and categorize them according to different aspects. In addition, this review investigates the protocols in terms of their forwarding processes, routing metrics, recovery mechanisms, and performance. Moreover, routing challenges and comparisons are discussed.

“…• While calculating vehicular density direction of vehicles should be taken into account. In particular, routes with vehicles moving towards a destination in high density will have less breakage probability than routes with the same density but with vehicles moving away from destination, as stated in [31]. • Forwarding collector packets, which measure routing metrics, along a path using greedy forwarding may result in loosing such packets.…”

Vehicular ad hoc networks (VANETs) are gaining tremendous interest among researchers and industries. Although the main reason for developing VANETs is traffic safety, many applications such as traffic status monitoring, road traffic management, routing and distribution of data, have emerged. VANETs exploit multi-hop communications among vehicles to deliver data packets. However, with fast mobility and intermittent link connectivity between vehicles, efficient and reliable routing in VANETs is becoming a challenging task. In order to make routing protocols robust to frequent communication disruptions and aware of unstable traffic and network conditions, several new routing metrics have been integrated with routing protocols. Such protocols are called traffic aware routing (TAR) protocols as their routing decisions are influenced by traffic and network status. The goal of this paper is to review the most recent traffic aware routing protocols while emphasising on traffic and network conditions awareness issues. In addition, this review investigated TAR protocols capabilities and limitations in terms of routing process, routing metrics measurement, forwarding mechanisms and recovery techniques. Moreover, challenges, critical issues and open research problems were discussed in the "Challenges and issues to consider" sections.

“…Papageorgiou'et al (2012) discuss an implementation, which adds on a module for ns-2 to provide more realistic mobility models. Further examples include Oliveira et al (2013) [83] looking at high mobility vehicular ad hoc networks, [84,85] considering connectivity in disaster response, and Bernsen and Manivannan (2012) [86] evaluating their VANET routing protocol, Reliable Inter-Vehicular Routing (RIVER). ns-2 is so commonly used and so well-known in MANET research that many papers merely state that it has been used with no discussion or justification at all.…”

A mobile ad hoc network (MANET) is a self-configuring wireless network in which each node could act as a router, as well as a data source or sink. Its application areas include battlefields and vehicular and disaster areas. Many techniques applied to infrastructure-based networks are less effective in MANETs, with routing being a particular challenge. This paper presents a rigorous study into simulation techniques for evaluating routing solutions for MANETs with the aim of producing more realistic simulation models and thereby, more accurate protocol evaluations. MANET simulations require models that reflect the world in which the MANET is to operate. Much of the published research uses movement models, such as the random waypoint (RWP) model, with arbitrary world sizes and node counts. This paper presents a technique for developing more realistic simulation models to test and evaluate MANET protocols. The technique is animation, which is applied to a realistic scenario to produce a model that accurately reflects the size and shape of the world, node count, movement patterns, and time period over which the MANET may operate. The animation technique has been used to develop a battlefield model based on established military tactics. Trace data has been used to build a model of maritime movements in the Irish Sea. Similar world models have been built using the random waypoint movement model for comparison. All models have been built using the ns-2 simulator. These models have been used to compare the performance of three routing protocols: dynamic source routing (DSR), destination-sequenced distance-vector routing (DSDV), and ad hoc n-demand distance vector routing (AODV). The findings reveal that protocol performance is dependent on the model used. In particular, it is shown that RWP models do not reflect the performance of these protocols under realistic circumstances, and protocol selection is subject to the scenario to which it is applied. To conclude, it is possible to develop a range of techniques for modelling scenarios applicable to MANETs, and these simulation models could be utilised for the evaluation of routing protocols.
