Embodiment Construction

[0046] Embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0047] A method for evaluating vehicle mobility in the Internet of Vehicles, the Internet of Vehicles includes a media server and a plurality of vehicles communicatively connected to the media server.

[0048] The evaluation method is as follows.

[0049] A1. Each vehicle determines its own trajectory according to the road network, and uploads the trajectory to the media server.

[0050] A1.1. Carry out grid processing on the road network. The specific method is to use the road as the context of the grid, the beginning and end of the road as the endpoint of the line, and the intersection between different roads as the intersection of the line. The meshing of the road network can be done either autonomously by the vehicle or by a media server. When the vehicle is autonomous, the vehicle can process the map of the area according to the navigation equi...

Abstract

The invention provides a method for evaluating the vehicle mobility in the Internet of Vehicles. The Internet of Vehicles comprises a media server and a plurality of vehicles in communication connection with the media server. The evaluation method comprises the following steps: A1, each vehicle determines an own mobile trajectory according to a road network, and uploads the mobile trajectory to the media server; A2, the media server extracts a travelling mode between an arbitrary departure place and an arbitrary destination in the road network according to the mobile trajectories uploaded by all vehicles; and A3, the media server determines the travelling mode of the current vehicle according to the departure place of the current vehicle and shares the judgment result with all vehicles. Byadoption of the method for evaluating the vehicle mobility the position and the travelling trajectory of the vehicle can be accurately determined, the travelling mode of the vehicle is determined according to the travelling trajectory of the vehicle, and meanwhile an application mode of the evaluation method in the video transmission field is also provided and can improve the video transmission rate and stability of the vehicles in the Internet of Vehicles.

Description

technical field [0001] The invention relates to the technical field of vehicle ad hoc networks, in particular to an evaluation method for vehicle mobility in the Internet of Vehicles and its application in the field of video transmission. Background technique [0002] The rapid development of wireless communication technology has greatly improved the communication capabilities of the network to meet the bandwidth requirements of video service applications in wireless mobile networks. Mobile users can access the Internet to obtain video content through smart terminal devices, such as smart phones and notebooks computer. Video services can provide users with rich visual content, and can attract ultra-large-scale video users. Therefore, the rapid increase in the scale of video users leads to relatively limited available bandwidth resources in the video system, which seriously affects the scalability of the video system and the user's quality of experience. Such as figure 1 A...
