摘要:

在本文中,我们解决的网络和通信问题,创建一个数字副本的Metaverse数字孪生。具体来说,负责创建和渲染Metaverse的虚拟服务提供商(VSP)需要使用物联网设备收集的数据来创建物理世界的虚拟副本。然而,由于物联网设备收集的数据量巨大(例如,图像和视频)以及有限的带宽,VSP可能无法从物理世界中检索所有所需的数据。此外,Metaverse需要快速复制(例如,再现),从而增加了对数据传输延迟的更多限制。为了解决上述挑战,我们建议为物联网设备配备语义信息抽取算法,以最小化通过无线信道传输的数据的大小。由于许多物联网设备将有兴趣出售他们的语义信息的VSP,我们提出了一个真实的反向拍卖机制,帮助VSP选择只有物联网设备,可以通过语义信息提高其虚拟副本的对象的质量。我们对包含同步相机和雷达图像的数据集进行了广泛的模拟,并表明我们的新颖设计能够以高精度快速复制数字副本。

英文摘要:

In this paper, we address the networking and communications problems of creating a digital copy in the Metaverse digital twin. Specifically, a virtual service provider (VSP) which is responsible for creating and rendering the Metaverse, is required to use the data collected by IoT devices to create the virtual copy of the physical world. However, due to the huge volume of the collected data by IoT devices (e.g., images and videos) and the limited bandwidth, the VSP might become unable to retrieve all the required data from the physical world. Furthermore, the Metaverse needs fast replication (e.g., rendering) of the digital copy adding more restrictions on the data transmission delay. To solve the aforementioned challenges, we propose to equip the IoT devices with semantic information extraction algorithms to minimize the size of the transmitted data over the wireless channels. Since many IoT devices will be interested to sell their semantic information to the VSP, we propose a truthful reverse auction mechanism that helps the VSP select only IoT devices that can improve the quality of its virtual copy of objects through the semantic information. We conduct extensive simulations on a dataset that contains synchronized camera and radar images, and show that our novel design enables a fast replication of the digital copy with high accuracy.
