Cloud Based IoT Network Virtualization for Supporting Dynamic Connectivity among Connected Devices

Abstract

Internet of Things (IoT) is considered one of the future disruptive technologies and has attracted lots of research attention in the recent past. IoT devices are tiny sensing or actuating devices attached to daily life objects, capable of sending sensing data and receiving commands. Cloud computing technology provides tremendous computing and storage capacity over the Internet to overcome limited resources of IoT devices. Many studies are conducted on IoT device virtualization in the cloud environment to facilitate remote access and control. In the future, IoT devices will be accessed through its corresponding virtual objects. Just like the network of physical devices, there needs to be a network of virtual objects in the cyber world. In this paper, we present a concept of building a dynamic virtual network in the cloud environment among connected IoT devices. The key idea is to provide a mechanism for building a virtual network among connected IoT devices from different domains through their corresponding virtual objects in the cloud environment. This will facilitate the sharing of resources and the rapid development of diverse applications on top of the virtualization layer by establishing a dynamic end-to-end connection between IoT devices. In this study, we present a detailed design of the proposed system for building a virtual IoT network. We have also implemented three application layers protocols in OMNET++ for simulation of a virtual objects network to conduct performance analysis of the proposed IoT network virtualization.

COVID-19 what have we learned? The rise of social machines and connected devices in pandemic management following the concepts of predictive, preventive and personalized medicine

“…An approach to managing new mass surveillance technology that links personal data would be to enable the consolidation of connected devices into virtual objects for remote access and control. This could create a dynamic virtual network connecting different domains and facilitating sharing of resources in a cloud environment [18]. This would allow us to initiate the development of a truly global response and monitoring of pandemics.…”

“…Open sharing of such personal medical data would require people to trust in technologies such as the secure multiparty computation (also known as privacypreserving computation) 17 and differential privacy. 18 Such technologies could enable a broader interpretation, based on trust in privacy preserving technologies. More work needs to be done on identifying and promoting the benefits for private individuals to start sharing openly medical data.…”

“…Social networks with large numbers of participants can provide answers to complex problems [6]. The virtualisation of IoT devices into virtual objects for remote access and control creates a dynamic virtual network connecting different domains, facilitating sharing of resources in a cloud environment [18]. This creates opportunities for fast and diverse application development through a dynamic end-to-end connection between devices that include those following.…”

A Novel Approach towards the Design and Implementation of Virtual Network Based on Controller in Future IoT Applications

“…However, these solutions do not provide an integrated approach to support the entire IoT system development process from analysis to implementation and often tend to solve a specific problem simultaneously. However, this partial approach led to poor interoperability of the "intranet" system, insufficient scalability or manageability of applications, leaving the original IoT embedded vision [23][24][25]. Therefore, we will develop a horizontal environment concept for interacting networked, physical, and networked physical systems, providing a comprehensive, application-independent methodological approach to developing IoT systems.…”

Design and Implementation of an Interworking IoT Platform and Marketplace in Cloud of Things

“…The framework summarizes the heterogeneity of a large number of different devices or objects while increasing reliability and making it easier to consider the views of different users. Integrated virtualization has become an effective way to reduce costs, improve software quality and reduce development time [21,22].…”
