“…Qi W J et al proposed a routing mechanism called TDCR in [13], which realizes the hybrid application of DSRC and C-V2X under consideration of the balance between the QoS requirements of different traffic and communication costs of users. In [17], Elbal BR et al realized a hybrid framework with C-V2X as the main communication means and DSRC as a blind-compensation communication measure. In this work, V2V communication is also used to enhance cellular network base station signals.…”

“…Therefore, DSRC has not been abandoned in both academia and industry and is still widely used in road warning, vehicle networking, and other fields. In recent years, many scholars have combined two vehicular communication technologies into one in-vehicle communication framework for research, achieving good results [13][14][15][16][17].…”

“…Research on hybrid applications of DSRC and C-V2X can be divided into two categories. One is the hybrid when different vehicles are equipped with different communications equipment (that is, some vehicles are only equipped with C-V2X equipment, and some vehicles are only equipped with DSRC equipment) [17]. In this scenario, the data format needs to be changed continuously during communication, and the communication management is more complicated.…”

“…Another important point is that the RSU was located in the middle of the road in the experiment. In addition, in the simulation program, the position of the vehicle was updated every 0.1 s. In previous vehicular communication simulations, there were insufficient numbers of vehicles [16,17,19,20], or insufficient mobility of vehicles (vehicles either did not move [16] or moved at a constant speed [21]). In this paper, the driving conditions of the vehicle in the real environment were fully imitated in the simulation environment to reflect the real performance of the vehicle communication method.…”

With the continuous development of connected and automated vehicles (CAVs) and Internet of Vehicle (IoV) technologies, various application scenarios have put forward higher requirements for vehicular communications. On the one hand, applications related to vehicle driving safety require lower latency and higher throughput. On the other hand, users who use cellular vehicle-to-everything (C-V2X) to transfer data will have to face high communication fees due to the increasing amount of data. Therefore, from the perspective of balancing quality of service (QoS) and user communication costs, this paper integrates dedicated short-range communication (DSRC) and C-V2X, two vehicular communication technologies with their own advantages, into a framework called cluster-based traffic differentiated hybrid routing (CTDHR), to provide services for in-vehicle communication. A vehicle clustering method based on hierarchical clustering is proposed to solve problems (e.g., the communication linking being difficult to maintain and the frequent cell handover due to high-speed movement of vehicles). The CTDHR framework is modeled on the resulting clusters and an objective equation was established. Finally, since the obtained objective equation is a nonlinear integer programming problem, we propose a heuristic algorithm to solve this optimization problem. In the simulation experiments, CTDHR shows better communication performance than the existing DSRC and C-V2X hybrid models. The experimental results show that CTDHR can reduce the communication costs of users while satisfying QoS.
