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

“…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.…”

Optimized scheduling mechanism based on IEEE 802.1Qch standard in time-sensitive networking by Hongrui NIE, Shaosheng LI, Yong LIU

“…To address the problem of complex gating planning for generic time-aware shaper (TAS), a traffic scheduling mechanism of adaptive queue buffer size and hardware time slot length was proposed with the help of IEEE 802.1Qch standard.Taking traffic and network characteristics into account, a mixed integer linear programming routing and scheduling model was formulated to maximize the number of time-sensitive flows mapped to the target network and then further improve the network scheduling capability by balancing the traffic carried by each scheduling time slot.Moreover, the impact of traffic and network features on queue buffer and hardware scheduling time slot was obtained through different scenarios.Simulation results show that the proposed method could successfully deploy thousands of time-sensitive flows for solving the scheduling problem in local area networks, and can improve the scheduling success rate by up to 28% compared with other algorithms with feasible execution time.…”
