A Semantic-Based Belief Network Construction Approach in IoT

Abstract

Uncertainty is intrinsic in most of the complex systems, especially when the systems have to interact with the physical environment; therefore, handling uncertainty is critical in the Internet of Things (IoT). In this paper, we propose a semantic-based approach to build the belief network in IoT systems to handle the uncertainties. Semantics is the functionality description of any system component. Semantic Match mechanisms can construct the appropriate structures to compare the consistency between different sources of data based on the same functionality. In the approach, we define the belief property of every system component and develop the related algorithms to update the belief value. Furthermore, the related mechanisms and algorithms for data fusion and fault detection based on the belief property are described to explain how the approach works in the IoT systems. Several simulation experiments are used to evaluate the proposed approach, and the results indicate that the approach can work as expected. More accurate data are fused from the inaccurate devices and the fault in one node is automatically detected.

Decision-Making under Uncertainty for the Deployment of Future Hyperconnected Networks: A Survey

“…Hence, in the area of semantic data mining, several studies grounded on diverse approaches have been discussed, as presented in Table 1. IoT is a paradigm based on sensor interconnection, wherein the convergence with semantic data mining has become a popular research area [12,13,[17][18][19]. For example, in [14], the authors improved resource management for wireless networks that operate cooperatively based on frameworks where semantic web techniques are applied.…”

“…Here in after on physical device, RFID (Radio Frequency Identification) which is known as a chip [12], [31]. It serve transmission from sensor detection to server so it is the gateway to collect data [32], [33].…”

“…The last programming item require to transfer all data to web application, it was Constrained Application Protocol (CoAP) which is designed for resource-constrained networks as a light-weight version of Hypertext Transfer Protocol (HTTP). The semantic approach was appropriate to accurate with data fusion, and reliability with error detection, heterogeneous system handled directly via math and graphic mechanism [33]. In this layer security and privacy term must be regulated directly on programming [37], .…”
