一种基于WiFi Direct的车路信息交互方法
Method of vehicle-road information interaction based on WiFi direct
摘要
Abstract
The vehicle,vehicle⁃road information interaction based on short⁃range communication becomes a development trend of intelligent transportation. The method of vehicle⁃road information interaction based on WiFi direct is proposed,which is sending connection and information to the vehicle terminal by the roadside base station running in the network. With the de⁃mands of the users personalized information service,the method of WiFi direct automatic connection based on filtering informa⁃tion is proposed,that is the improvements based on WiFi direct technology and adding a frame filtering information in send⁃mes⁃sage data frame. The proposed method simplifies the connection between the base station and vehicle terminal,and improves the accuracy of message push. The field test shows that the connection speed is increased by 35.01% and the quantity of push mes⁃sages is increased by 8.65% by the improved method compared with the existing method.关键词
