Internet-of-vehicles environment oriented network performance comprehensive testing and evaluating analysis method

Abstract

The invention discloses an Internet-of-vehicles environment oriented network performance comprehensive testing and evaluating analysis method which comprises the following steps of 1, establishing a testing platform which comprises a first testing board, a second testing board and a background server, wherein the first testing board and the second testing board are respectively used for network performance testing and vehicle driving information acquisition, and the background server is used for data storage, analysis and processing; 2, in different testing scenes, testing a network performance index by means of an active measuring method and network tomography; 3, performing abnormal data processing on testing data according to a 3-sigma principle, and obtaining a testing result by means of Bootstrap estimation and maximum likelihood estimation; and 4, performing evaluation and comparative analysis on the testing result by means of an Internet-of-vehicles performance comprehensive index evaluation method. The Internet-of-vehicles environment oriented network performance comprehensive testing and evaluating analysis method can realize comprehensive network performance measurement on the Internet-of-vehicles and can more visually and more effectively reflect network performance and change.

Description

technical field [0001] The invention relates to the Internet of Vehicles, in particular to a network performance comprehensive test, evaluation and analysis method for the Internet of Vehicles environment. Background technique [0002] Compared with traditional wireless communication networks, the application environment of Internet of Vehicles is more complex. Vehicles are moving at high speed during driving, communication interference and multipath fading have brought challenges to the wireless communication of the Internet of Vehicles. Therefore, how to test and evaluate the performance of IoV communication has become an urgent problem to be solved. [0003] IEEE 802.11p is considered to be a standard specially designed for IoV, but it has obvious disadvantages such as poor reliability, hidden nodes, infinite delay and intermittent V2I connectivity. From an industrial point of view, the widespread deployment of IEEE 802.11p requires a huge investment in network infrastr...
