The invention claims protection of a V2X network performance test, evaluation and analysis method, which relates to the field of vehicle networking network performance test and analysis. It includes: building LTE network performance test and DSRC network performance test platform; carrying out LTE and DSRC network performance in the Internet of Vehicles environment, determining network performance indicators and calculating network performance index values; combining entropy weight method and analytic hierarchy process to determine the The weight of the performance index. Calculate the efficacy score of each performance index, and obtain the comprehensive performance evaluation score through weighted calculation with the weight of each performance index, and obtain the quantitative analysis result; use the fuzzy comprehensive analysis method combined with the comprehensive weight to obtain the qualitative analysis result; combine the quantitative analysis result and the qualitative The analysis results are comprehensive analysis and evaluation results. The present invention comprehensively considers the impact of various performance indicators of the Internet of Vehicles on the network performance by actually testing the network performance parameters in the Internet of Vehicles environment, thereby more accurately evaluating the network performance of the Internet of Vehicles.
Description
technical field [0001] The invention belongs to the field of Internet of Vehicles, and in particular relates to a V2X-based network performance test and comprehensive evaluation method. Background technique [0002] The so-called V2X means vehicle to everything, that is, the information exchange between the vehicle and the outside world. It includes vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), vehicle-to-infrastructure (V2I) and vehicle-to-network (V2N) communications to improve road safety as well as traffic efficiency. The Internet of Vehicles has laid a new direction for the development of automotive technology by integrating Global Positioning System (GPS) navigation technology, vehicle-to-vehicle communication technology, wireless communication and remote sensing technology, and realized the compatibility of manual driving and automatic driving. Models equipped with this system can automatically select the driving route with the best road conditions through t...
