Abstract

The invention discloses an adaptive feedback control method of Basic Safety Message (BSM) in Cooperative Vehicle Safety System (Cooperative Vehicle Safety System, CVSSs). situation, hide the impact of the terminal and the channel bit error rate, and calculate the information dissemination rate (Information Dissemination Rate, IDR) to provide the basis for the prediction model; use the prediction model to give the idealized network performance, and the ideal network state is regarded as To obtain the maximum IDR, the ideal IDR is used as a benchmark to guide the BSM rate adaptive feedback control; the feedback rate control model is used to make the error between the ideal IDR and the actual IDR converge to zero. Compared with the prior art, the present invention fully considers the factors that adversely affect IDR, can improve the real-time vehicle tracking accuracy in different vehicle networking environments and network environments, and improve the robustness of CVSSs under different interference effects.

Description

technical field

[0001] The invention relates to the technical field of Internet of Vehicles communication, in particular to an adaptive feedback control method for basic safety messages in a cooperative vehicle safety system. Background technique

[0002] Vehicular Ad Hoc Networks (VANETs) are considered to be an important part of Intelligent Transportation System (ITS). Its goal is to improve road safety. VANETs improve road safety through vehicle-to-vehicle (V2V) communication, providing various active safety applications, such as cooperative collision warning, electronic emergency braking, etc., collision warning and overtaking warning, etc. However, these active safety applications require each vehicle to have a good estimate of the location and status of surrounding vehicles. These messages are regularly broadcast on the shared channel through Basic Security Messages (BSM). Vehicles use BSM to detect possible collisions and warn the driver. This concept is called Co...
