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 vehicle moving behavior similarity in the Internet of Vehicles comprises the steps of S1, calculating road flow based on historical traffic data of a road, andrepresenting the time cost of the passing road by using the road flow in a corresponding time interval; S2, representing the path cost of the passing road by using the length of the road; S3, converting the path cost into a weight value, calculating the road travel cost by combining the weight value with the time cost, and obtaining a travel mode between any starting point and any ending point through the road travel cost; S4, calculating moving behavior similar duration between the vehicles based on the driving modes of the vehicles; and S5, if the similar duration of the moving behaviors between two vehicles is greater than a video sharing duration required for transmitting the video resources, transmitting the video resources between the two vehicles. Whether the vehicles are suitablefor video resource sharing or not is judged by accurately describing the similarity of the vehicle moving behaviors, the stability of a video resource sharing process can be guaranteed, and the user experience is improved.

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...
