The Internet of Vehicles (IoV) involves a network of numerous vehicles equipped with relatively low-powered wireless communication devices. These vehicles communicate with each other and potentially with roadside units (RSUs) to facilitate various applications, including traffic management, road safety, and infotainment services. To ensure scalability in IoV, the authors have employed a RSUs partition technique. Clustering serves as a routing strategy to group sensor nodes, enabling them to communicate exclusively with their designated cluster head (CH). Subsequently, the information gathered by the CH gets relayed to the base station (BS) or a sink. In this paper, we proposed a Controller-IoV-based RSU partition. We simulated the proposed method in MATLAB, which revolves around optimizing load distribution while minimizing overhead between RSUs and other vehicular components. Further, we have also discussed the experimental results and future directions.
