摘要:

Metaverse有望在5G高数据速率通信技术的支持下,创造一个与现实紧密相连的虚拟世界,为用户提供身临其境的体验。物理世界中的大量数据需要同步到虚拟世界,为用户提供沉浸式体验,并且将更多用户纳入Metaverse对覆盖率提出更高要求。然而,5G信号遭受严重衰减,这使得维持相同覆盖范围的成本更高。无人机(UAV)是未来实现Metaverse作为低成本和高移动性通信设备平台的一种有前途的候选技术。本文提出了一种基于最近策略优化(PPO)的双智能体协同强化学习方法,用于无人机的信道分配和轨迹控制,实现从物理世界到虚拟世界的数据收集和同步,经济地扩大Metaverse服务的覆盖范围。仿真结果表明,我们提出的方法是能够实现更好的性能相比,基准方法。

英文摘要:

Metaverse is expected to create a virtual world closely connected with reality to provide users with immersive experience with the support of 5G high data rate communication technique. A huge amount of data in physical world needs to be synchronized to the virtual world to provide immersive experience for users, and there will be higher requirements on coverage to include more users into Metaverse. However, 5G signal suffers severe attenuation, which makes it more expensive to maintain the same coverage. Unmanned aerial vehicle (UAV) is a promising candidate technique for future implementation of Metaverse as a low-cost and high-mobility platform for communication devices. In this paper, we propose a proximal policy optimization (PPO) based double-agent cooperative reinforcement learning method for channel allocation and trajectory control of UAV to collect and synchronize data from the physical world to the virtual world, and expand the coverage of Metaverse services economically. Simulation results show that our proposed method is able to achieve better performance compared to the benchmark approaches.
