“…The protocol tries to avoid the clustering phenomenon under the influence of traffic lights and to select the road section by disseminating information among more vehicles. Li et al [25] have presented multihop transmission latency and connection probability in the analysis of multihop links from the 5G enabled vehicular networks. In [26], the authors have proposed a reliable IP-based routing in VAENT with network gaps based on road segments and virtual nodes that can form routing paths without network gaps (the network gap occurs when the distance between two nonadjacent vehicles is more than the transmission radius).…”

The routing process in vehicular ad hoc networks (VANETs) is a challenging task in urban areas which is due to the high mobility of vehicles, repetitive defects of the communication path, and the various barriers that may affect the reliability of data transmission and routing. Accordingly, the connectivity in vehicular communications has received the researchers’ attention, so different geographic routing protocols have been proposed in this respect. Unmanned aerial vehicles (UAVs) are useful for overcoming routing constraints. Cloud computing has also been defined as a new infrastructure for VANET which is made up of a significant number of computing nodes including stable data centers as well as a set of mobile computing devices embedded on vehicles. The aim of this research is to simulate a VANET in an urban area using cloud computing infrastructure and applying unmanned aerial vehicles (UAV) so that the negative influence of barriers in packet delivery and routing is avoided. To evaluate, the proposed method is compared with the basic protocol ClouDiV. Ns-2 simulation results show that the proposed method outperforms with different densities and variable times in terms of efficiency and performance.

5G vehicular communication is one of key enablers in next generation intelligent transportation system (ITS), that require ultra-reliable and low latency communication (URLLC). To meet this requirement, a new hybrid vehicular network structure which supports both centralized network structure and distributed structure is proposed in this paper. Based on the proposed network structure, a new vehicular network utility model considering the latency and reliability in vehicular networks is developed based on Euclidean norm theory. Building on the Pareto improvement theory in economics, a vehicular network uplink optimization algorithm is proposed to optimize the uplink utility of vehicles on the roads. Simulation results show that the proposed scheme can significantly improve the uplink vehicular network utility in vehicular networks to meet the URLLC requirements.

“…The high reliability of the communication link is the basis for ICVs to realise information exchange. However, because of the mobility of vehicles, the high reliability of vehicular communication is facing challenges such as poor link connectivity and long transmission delay [9][10][11][12]. In addition, the big data processing brings unprecedented challenges unseen in traditional wireless networks, because of the increase of ICVs and various service applications as well as the requirements for timely and accurate acquisition of traffic information [13].…”

In vehicular relay networks, the quality of communication link has a significant impact on the stable and reliable communication requirements. Most earlier studies focused on the influence of relay probability on link connectivity while little attention has been paid to the impact of packet collision. In complex mobile scenarios, vehicle density is proportional to relay probability, while proportional to data packet collision probability. Meanwhile, vehicle density and packet collision affect the quality of communication link in the relay network. This condition inspires them to study the link connectivity in vehicular relay networks based on carrier sense multiple access with collision avoidance. First, the relationships among vehicle density, vehicle speed, packet collision probability and relay probability are studied in relay communication. Second, due to the high‐speed movement of vehicles, an analysis model, considering the mobility of vehicle nodes, is conducted to analyse the downlink performance in relay communication networks. Finally, a platoon scheme is proposed to reduce packet collision probability, considering the vehicle density and backoff window size on vehicle‐to‐roadside unit communication. Extensive numerical results indicate that the platoon model has a great advantage in terms of downlink performance, especially in the case of dense traffic flow.
