“…Furthermore, the protocol must be evaluated and analyzed using various conventional QoS metrics. CLHLB [135] combines V2I and V2V cross-layer routing to deliver packets with high efficiency at different traffic densities using path connectivity probability. Simulation results demonstrated a significant gain in PDR and average delay compared with many routing strategies.…”

“…In [135], Gao et al proposed a path connectivity-based crosslayer unicast geographic routing handoff method using SDVN to ensure efficient data delivery at different traffic densities. The cooperation between the V2V cross-layer and V2I routing occurs based on the number of backbone paths whose connectivity probability exceeds a threshold.…”

As the automotive and telecommunication industries advance, more vehicles are becoming connected, leading to the realization of intelligent transportation systems (ITS). Vehicular ad-hoc network (VANET) supports various ITS services, including safety, convenience, and infotainment services for drivers and passengers. Generally, such services are realized through data sharing among vehicles and nearby infrastructures or vehicles over multi-hop data routing mechanisms. Vehicular data routing faces many challenges caused by vehicle dynamicity, intermittent connectivity, and diverse application requirements. Consequently, the software-defined networking (SDN) paradigm offers unique features such as programmability and flexibility to enhance vehicular network performance and management and meet the quality of services (QoS) requirements of various VANET services. Recently, VANET routing protocols have been improved using the multilevel knowledge and an up-to-date global view of traffic conditions offered by SDN technology. The primary objective of this study is to furnish comprehensive information regarding the current SDN-based VANET routing protocols, encompassing intricate details of their underlying mechanisms, forwarding algorithms, and architectural considerations. Each protocol will be thoroughly examined individually, elucidating its strengths, weaknesses, and proposed enhancements. Also, the software-defined vehicular network (SDVN) architectures are presented according to their operation modes and controlling degree. Then, the potential of SDN-based VANET is explored from the aspect of routing and the design requirements of routing protocols in SDVNs. SDVN routing algorithms are uniquely classified according to various criteria. In addition, a complete comparative analysis will be achieved to analyze the protocols regarding performance, optimization, and simulation results. Finally, the challenges and upcoming research directions for developing such protocols are widely stated here. By presenting such insights, this paper provides a comprehensive overview and inspires researchers to enhance existing protocols and explore novel solutions, thereby paving the way for innovation in this field.

“…Since the V2V cross‐layer routing protocol does not guarantee different types of vehicle density, Yangshui et al introduced a probability model of the connected route which depends on cross‐layer routing handoff strategy while software‐defined vehicle ad hoc networks (SDVN) are considered 42 . In their scheme probability of the obtained connected path was taken into account to select V2I station routing or V2V cross‐layer routing.…”

SummaryVehicular connectivity is a significant key contribution in vehicular ad‐hoc networks (VANETs). The inherent high dynamicity of vehicles is a serious challenge that affects automotive connectivity and disrupts inter‐vehicle communications stability. Vehicle‐to‐everything (V2X) communication enables vehicles to connect to any other networks and facilitates the evolutionary trend of automotive innovations toward autonomous internet‐enabled intelligent vehicles. In this article, we provide a systematic literature review (SLR) for vehicular connectivity and V2X communications by investigating 58 research articles from 2018 to 2023 in VANETs. We propose six fundamental research questions (RQs) and a taxonomy to systematize the study of the baseline articles and answer the crucial RQs. This SLR can be helpful for researchers as a complete study focusing on V2X analysis, making it possible to achieve Technical Aspects and New challenges.
