Energy-saving type wireless video business resource scheduling method based on user experience

Abstract

The invention discloses an energy-saving type wireless video business resource scheduling method based on user experience. Video distortion in wireless video transmission business is mainly caused by two parts, namely the distortion of an information source introduced during the encoding process and the distortion of a channel caused by transmission of video packets in an unreliable wireless channel. The power consumption of a system during the wireless video transmission business can be divided into video encoding power and video transmission power. Based on the energy-saving type wireless video business resource scheduling method, a power-business and system parameter-QoE (quality of experience) mapping model is established, and the video encoding rate and parameters of an AMC (adaptation mode controller) mode are utilized as intermediate variables for establishing a mapping model between the power consumption of the system and subjective perceptual quality of users. A target function is established according to the model so as to realize the purposes of reducing the power consumption of the system, saving energy and reducing emission on the basis of meeting the subjective perceptual quality of the users; and a PSO (particle swarm optimization) algorithm is adopted for performing resource scheduling and distribution for all the users. By adopting the technical scheme disclosed by the invention, the problems of large power consumption of the system and incapability of ensuring the subjective perceptual quality of the users in the current wireless video transmission business can be solved.
