Digital Object Architecture for IoT Networks

Abstract

The Internet of Things (IoT) is a recent technology, which implies the union of objects, "things", into a single worldwide network. This promising paradigm faces many design challenges associated with the dramatic increase in the number of end-devices. Device identification is one of these challenges that becomes complicated with the increase of network devices. Despite this, there is still no universally accepted method of identifying things that would satisfy all requirements of the existing IoT devices and applications. In this regard, one of the most important problems is choosing an identification system for all IoT devices connected to the public communication networks. Many unique software and hardware solutions are used as a unique global identifier; however, such solutions have many limitations. This article proposes a novel solution, based on the Digital Object Architecture (DOA), that meets the requirements of identifying devices and applications of the IoT. This work analyzes the benefits of using the DOA as an identification platform in modern telecommunication networks. We propose a model of an identification system based on the architecture of digital objects, which differs from the well-known ones. The proposed model ensures an acceptable quality of service (QoS) in the common architecture of the existing public communication networks. A novel interaction architecture is developed by introducing a Middle Handle Register (MHR) between the global register, i.e., Global Handle Register (GHR), and local register, i.e., Local Handle Register (LHR). The aspects of the network interaction and the compatibility of IoT end-devices with the integrated DOA identifiers in heterogeneous communication networks are presented. The developed model is simulated for a wide-area network with allocated registers, and the results are introduced and discussed.

Establishment of Web-Based Digital Twin System for Truss Gantry Crane

“…Using IoT, AI and other technologies, the digital twin can monitor and optimise the production process in real time, reduce energy consumption and waste disposal costs, and reduce the impact of the business on the environment. Moreover, the digital twin system can monitor the status of equipment and production lines in real time, and through data analysis and simulation, it can predict potential malfunctions and equipment failures, and carry out repairs and maintenance in advance, which can reduce unexpected malfunctions and down times, and improve the availability and productivity of equipment [29].The above study shows that the use of digital twins has good results compared to traditional operation, management and fault prediction [30]. However, digital twins are dynamic rather than static [31], so the realtime and compatibility of data transmission is yet to be challenged [32].…”

Multipath Routing Scheme for Optimum Data Transmission in Dense Internet of Things

“…The Internet of Things (IoT) has become integral to modern info-communication systems [1,2]. According to the forecasts of leading manufacturers, the number of wireless devices connected to communication networks will grow in the foreseeable future [3]. A large number of connected devices leads to the formation of high-density networks, which have several features associated with significant mutual influences between nodes [4][5][6].…”

Enhancing IoT Network Security Through Digital Object Architecture-Based Approaches

“…In our study, we have introduced a technique in [15] that utilizes the Digital Objects Architecture (DOA) to identify Internet of Things (IoT) devices and applications in diverse networks. The model presented in reference [11] ensures a satisfactory level of quality of service (QoS) within the existing framework of public communication networks. A unique interaction architecture has been proposed, which incorporates a Middle Handle Register (MHR) situated between the Global Handle Register (GHR) and the Local Handle Register (LHR).…”
