Abstract: The paper proposes a distributed simulation architecture that integrates VISSIM, MATLAB and NS-3 to evaluate V2X (Vehicle-to-Everything) applications, with a focus on designing a Model Predictive Control (MPC)-based platoon controller. By default, NS-3 does not support Wi-Fi distributed simulation. This paper proposes an alternative strategy to parallelise and increase efficiency. The proposed architecture with two processors reduces execution time by up to 50% while maintaining high accuracy in results, and the Packet Delivery Ratio (PDR in %) deviation is less than 2%, indicating a cost-effective simulation of V2X applications. Compared to existing methods in the literature, the proposed architecture outperforms in terms of time savings and accuracy. By reducing the time and resources required for field trials, the proposed architecture accelerates the development and testing of V2X applications for improved safety and efficiency of transportation networks.
