Proposed IIoT communication model (IMAGE) Beijing Zhongke Journal Publising Co. Ltd. Caption The proposed network can be characterized as an aggregating digital twin network because the nodes are of a large volume inside the industry. Each of the nodes is near the other nodes, which can cause data redundancy. With the correct collection and transmission methods in the digital twin, this can be avoided. This results in less network congestion and less energy but increased computing performance and memory. Figure 1 shows the proposed digital twin communication model with a multi-access edge-cloud framework. The proposed IIoT communication model, consists of three layers. The first layer constitutes the physical, connectivity, or network and abstraction sublayers. Specifically, in the physical sublayer, various devices are installed. In the connectivity sublayer, the devices are connected in a way and topology so that they can produce and transfer data over time. In the abstraction sublayer, the differences between the valuable information and the total data generated, have been reduced. The second layer comprises ESs, a database, and a broker. Specifically, the valuable data produced are forwarded through the broker device to the ESs for a good real-time manipulation and management and finally stored for a specific period of time inside the local database. The third layer consists of an application, a CS, and a cloud database. Specifically, the application updates data stored in the local database in real time efficiently, and cloud services are provided for complex analytics and longterm storage.
