基于V2X应用场景的专用短程通信性能道路测试研究
|
摘要
基于试车场道路测试,研究了不同V2X应用场景下专用短程通信(DSRC)的时延和丢包率,重点分析了通信距离、车辆运动状态、障碍物类型等3方面因素对"车-车""车-路"通信性能的影响。同时,基于路径损耗理论和遮蔽效应理论,建模分析并阐释了试验结果的内在机理。研究结果表明,DSRC丢包率随着通信距离的增加而提高,时延和丢包率在建筑物等遮蔽环境下显著提高。
In this study, DSRC(Dedicated Short Range Communication) performances including latency and packet loss rate were studied under various V2 X scenarios based on track tests. Analysis focused on the effects of distance, vehicle motion state and type of obstacle on the communication performances of V2 V and V2 I. Modeling and analysis were conducted and the internal mechanism of the test results was interpreted based on path loss theory and shadow fading theory. Results indicate that the DSRC packet loss rate increases with the increase of communication distance, the latency and packet loss rate increase significantly in the shadow environment like buildings.
