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.

Globalization has changed the way goods and services are produced. The activities that form the value chains of many products and services are increasingly fragmented across the globe and between firms. But the question is how we get positive economic and social benefits by taking part in these global value chains. In the case of Morocco, it appears that the current form of its integration in Global Value Chains (GVCs) has only a limited effect on economic growth in the long-term. Indeed, despite the continued growth of Moroccan exports since 2011, the local added value in these exports has not increased so much. Consequently, the current stage of Morocco in GVCs does not allow improvement of per capita income and employment rates. In this respect, moving upmarket in GVCs and discovering of a new, more complex sector is no minor detail, but proves to be an absolute necessity for the territorial development of Morocco.
