Embodiment Construction

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0073] see Figure 4 , a method for sharing video resources based on the similarity of vehicle movement behavior in the Internet of Vehicles. The Internet of Vehicles includes several roads and several vehicles driving on the roads. Each vehicle stores video resources. The sharing methods include S1 to S5.

[0074] S1. Calculate the road flow based on the historical traffic data of the road, and use the road flow in the corresponding time interval to represent...

Abstract

A video resource sharing method based on the similarity of vehicle movement behavior in the Internet of Vehicles, S1, calculate the road flow based on the historical traffic data of the road, and use the road flow of the corresponding time interval to represent the time cost of passing the road; S2, use the length of the road to represent the passing time The distance cost of the road; S3, convert the distance cost into a weight value and then combine it with the time cost to calculate the road driving cost, and obtain the driving mode between any starting point and any end point through the road driving cost; S4, vehicle-based driving mode Calculate the duration of the similar movement behavior between the vehicles; S5. If the similar duration of the movement behavior between the two vehicles is longer than the video sharing duration required to transmit the video resource, transmit the video resource between the two vehicles. The present invention judges whether the sharing of video resources between vehicles is suitable by accurately describing the similarity of the moving behavior of the vehicles, which can ensure the stability of the video resource sharing process and improve user experience.

Description

technical field [0001] The invention relates to the field of the Internet of Vehicles, in particular to a method for sharing video resources in the Internet of Vehicles based on the similarity of vehicle movement behavior. Background technique [0002] Vehicle networking (Vehicular ad hoc Networks, VANETs) is a huge interactive network composed of information such as vehicle location, speed and route, and is an extremely important next-generation Internet technology. The development of vehicle wireless communication technology (such as IEEE802.11p, 5G) has fostered many applications under the Internet of Vehicles. Video services are the most popular applications on the Internet. According to Cisco's forecast, by 2020, video traffic will account for 75% of global mobile traffic. The rapid growth of video traffic is due to the high usage rate of hundreds of millions of video users around the world (China's video users reached 578 million in 2017). Deploying video services i...
