Embodiment Construction

[0061] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0062] Different from the method of improving the network performance parameters as the optimization goal, the bandwidth allocation in the video transmission process should start from the perspective of the application layer, with the goal of improving the QoE (Quality of Experience) of the video. At present, more and more researches are beginning to learn from more mature QoE models to solve...

Abstract

The invention provides a bandwidth allocation method and device for multi-node video transmission and electronic equipment, and belongs to the field of wireless intelligent network communication. Themethod comprises the steps: determining a utility function for video experience quality according to the video rate range transmitted by each node; constructing a potential game model based on the utility function, wherein each node is a game participant of the potential game model; and solving Nash equilibrium of the potential game model through a distributed regret matching algorithm to obtain abandwidth allocation scheme of each node. According to the method, the potential function of the game is determined by constructing the potential game model, the Nash equilibrium of the potential function is solved through the distributed regret matching algorithm, the solution of the Nash equilibrium is the optimal channel bandwidth allocation scheme, so that convergence can be realized in a very short time, and meanwhile, the total utility value of the video is converged to a certain stable value; therefore, a more reasonable bandwidth allocation scheme and better overall utility can be obtained.

Description

technical field [0001] The invention relates to the field of wireless intelligent network communication, in particular to a bandwidth allocation method, device and electronic equipment for multi-node video transmission. Background technique [0002] With the rapid development of wireless communication technology, computer network and multimedia technology, various video services have become popular. Wireless network bandwidth resources cannot fully meet the rapidly growing demand for video transmission. Insufficient channel resources will cause multiple mobile video users to compete with each other, and the result will inevitably affect the quality of experience of the video (English: Quality of Experience, abbreviation: QoE) , therefore, there is an urgent need for reasonable bandwidth allocation among video transmission nodes. [0003] Existing bandwidth allocation methods usually start from the perspective of improving network performance parameters and enhancing service...
