Research on Simulation and Verification Platform of Vehicle-way Cooperative Algorithm Based on C-V2X 2020-01-1292
The V2X system covers three broad categories scenario of security, efficiency, and service, and each type of scenario can be refined into a number of specific application scenarios. It is difficult to verify the V2X system protocol stack and the application scenario algorithm during the period of the actual vehicle verification, in which it is difficult to cover the real-vehicle application working conditions of the comprehensive V2X system, especially the complex traffic condition. In order to verify the reliability and stability of the V2X system under various application conditions, a vehicle-way cooperative algorithm development framework and its simulation and verification platform are proposed. The development and verification process of the vehicle-mounted system based on the V model is taken into account by the algorithm development framework and the simulation platform, and the cross-application between the traffic simulation and the network simulation is constructed based on the SUMO and the NS3. First, the platform utilizes Simulink to set up the V2X sub-segment application scenario algorithm, secondly it makes use of SUMO to construct the traffic scenario, then it utilizes the NS3 to carry out multi-layer communication protocol simulation and setting based on C-V2X. Taking a high-priority vehicle in a V2X system as an example, the author give a complete algorithm development and a specific implementation method for simulation verification, then build a test scenario library of the application and finally verify the algorithm by the proposed verification platform. The experimental results verifies the feasibility and effectiveness of the proposed architecture and its simulation and verification platform.
