V2X network performance test and comprehensive evaluation analysis method

Abstract

The invention provides a V2X network performance test and evaluation analysis method, and relates to the field of network performance test analysis of the Internet of Vehicles. The method comprises the following steps: establishing an LTE network performance test and DSRC network performance test platform; testing the network performance of LTE and DSRC in an Internet of Vehicles environment, determining network performance indexes, and calculating network performance index values; and determining the weights of the network performance indexes in combination with an entropy weight method and an analytic hierarchy process; calculating the effect scores of the network performance indexes, performing weighted calculation on the weights of the network performance indexes to obtain a comprehensive performance evaluation score, and obtaining a quantitative analysis result; obtaining a qualitative analysis result by using a fuzzy comprehensive analysis method in combination with a comprehensive weight; and obtaining a comprehensive analysis evaluation result in combination with the quantitative analysis result and the qualitative analysis result. According to the V2X network performance test and evaluation analysis method provided by the invention, by actually testing the network performance parameters in the Internet of Vehicles environment and comprehensively considering the influence of various performance indexes of the Internet of Vehicles on the network performance, the network performance of the Internet of Vehicles can be evaluated more accurately.

Description

technical field [0001] The invention belongs to the field of vehicle networking, 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 the...

Problems solved by technology

In addition, because there is no current industry standard to measure the network performance of V2X communication, and there is also a lack of a specific V2X communication performance evaluation model, there is an urgent need to test the V2X bearer network and the evaluation method for V2X network performance
