    UAV service enhancement mechanism deep deterministic policy gradient for scalable video coding transmission by Junjie YAN, Yaxin ZHU, Yanru FENG, Hanyong LIU, Junyi DENG, Huan WANG

    Published 2023-08-01
    “…Unmanned aerial vehicles (UAV) are an important component of future air-space-ground integrated network due to their onboard storage, communication, and computing capabilities.However, existing research on UAV-assisted edge networks often focuses more on the network perspective and lacks consideration of user perspectives and their requirements.Therefore, a UAV service enhancement mechanism based on deep deterministic policy gradient (DDPG) for scalable video coding (SVC) transmission was proposed from the user’s perspective.Firstly, an elastic video transmission method based on SVC was proposed in conjunction with UAV to improve differentiated user experiences.Secondly, a UAV trajectory planning design based on the DDPG algorithm was proposed to maximize the number of users receiving enhanced layer videos and ensure effective coverage enhancement by UAV in hotspot areas.Simulation results show that compared with both the deep Q network (DQN) algorithm and shortest path (SP) algorithm under different user distributions, the proposed algorithm can increase the average number of enhanced layers received by 47.9% and 76.4%, respectively.This study successfully achieves improved coverage in hotspot areas while also providing differentiated user experiences through its proposed methods.…”

    Data transmission strategy of P2P pattern live video media streaming system by SUN Zhi-xin1, CHEN Ya-dang1, REN Zhi-guang1

    Published 2011-01-01
    “…An algorithm optimization was made with improved simulated annealing algorithm aimed at data transmission strategy of streaming media system in P2P networks.According with global layout,a mathematic model have been estab-lished for data transmission strategy of streaming media system in P2P networks named VMDTSA-P2P,which com-pletely have considered the affection of both the out-bandwidth and the available time,and take them as the object func-tion for getting the optimum solution.It also optimized the solutions with improved simulated annealing algorithm.Compared with traditional data transmission strategies,this improved algorithm accelerates the speed of new nodes choose the data provider from its partner nodes when there are lots of users and insures the solution of the data provider is approximate the best.Thus,the play delay of the streaming media system is decreased and the quality of video playback is increased.By realizing it in a simulated P2P system,the accuracy and the efficiency were both verified in the simulation.…”
