“…We leverage this method for TCPS by replacing the human operator with a known Proportional Integral (PI) controller and analyzing its response to the slave side step changes. In this section, we first describe the components of the TCPS testbed implemented in our lab [16]. We then describe how to conduct step response experiments using this testbed in both haptic and non-haptic settings to evaluate kinematic-haptic and kinematic-video loops, respectively.…”

We evolve a methodology and define a metric to evaluate Tactile Internet based Cyber-Physical Systems or Tactile Cyber-Physical Systems (TCPS). Towards this goal, we adopt the step response analysis, a well-known control-theoretic method. The adoption includes replacing the human operator (or master) with a controller with known characteristics and analyzing its response to slave side step disturbances. The resulting step response curves demonstrate that the Quality of Control (QoC) metric is sensitive to control loop instabilities and serves as a good indicator of cybersickness experienced by human operators. We demonstrate the efficacy of the proposed methodology and metric through experiments on a TCPS testbed. The experiments include assessing the suitability of several access technologies, intercontinental links, network topologies, network traffic conditions and testbed configurations. Further, we validate our claim of using QoC to predict and quantify cybersickness through experiments on a teleoperation setup built using Mininet and VREP.Index Terms-quality of control, tactile internet, tactile cyberphysical systems.

“…This is accomplished by replacing the human operator with a controller with known characteristics and analyzing its response to slave side step changes. We had introduced this framework to characterize control loop quality of TCPS in [16]. However, this work is the first attempt to use the step response method for evaluating TCPS.…”

“…The main features of the OVGU-HC are its experimental description language (DES-Cript), its experimental automation services, and the various hardware available for conducting experiments. Finally, an open Tactile Cyber-Physical Systems (TCPS) testbed is developed in [124], whose main purpose is rapid prototyping and evaluation of TCPS applications. Different from previous testbeds without assessment means, the engineers equip their testbed with tools for evaluating latency and management performance, which are key features of TCPS.…”

Dubbed "the successor to the mobile Internet", the concept of the Metaverse has grown in popularity. While there exist lite versions of the Metaverse today, they are still far from realizing the full vision of an immersive, embodied, and interoperable Metaverse. Without addressing the issues of implementation from the communication and networking, as well as computation perspectives, the Metaverse is difficult to succeed the Internet, especially in terms of its accessibility to billions of users today. In this survey, we focus on the edge-enabled Metaverse to realize its ultimate vision. We first provide readers with a succinct tutorial of the Metaverse, an introduction to the architecture, as well as current developments. To enable the ubiquitous, seamless, and embodied access to the Metaverse, we discuss the communication and networking challenges and survey cutting-edge solutions and concepts that leverage next-generation communication systems for users to be telepresent and teleoperate in the Metaverse. Moreover, given the high computation costs required, e.g., to render immersive 3D worlds and run data hungry artificial intelligence (AI) driven applications, we discuss the computation challenges and cloud-edge-end computation framework driven solutions to realize the Metaverse on resource-constrained edge devices. Next, we explore how blockchain technologies can aid in the interoperable development of the Metaverse, not just in terms of empowering the economic circulation of virtual usergenerated contents, but also to manage physical edge resources in a decentralized, transparent, and tamper-proof manner. Finally, we discuss the future research directions towards realizing the true vision of the edge-enabled Metaverse.

Tactile internet (TI) has emerged as a new possibility into revolutionizing whole society by involving human beings, communication aspects, and industrial operation. Main purpose of TI is to disseminate perceptual, that is, haptic information to remote industry machines for pouring skills and expertise as if it were actually accomplished by a person in reality. Internet of things is an established tool to serve various smart application development that mainly depends on sensors, actuators, communication technology, and cloud‐based services. Existing studies do not clearly mention the key requirements, architectural standardization and TI enabled functions to transfer haptic information via a suitable communication media. Although 5G has been considered as a valuable core of TI infrastructure, lack of actual implementation and related evidence has raised a dilemma about its effectiveness for industry applications leaving with no direction. In this article, we present architectural and system model‐wise development of tactile internet of things for possible industry application realization. We also present key requirements, functional and optimal aspects of tactile internet of things. Study of potential communication technologies and state‐of‐the‐art study on recent works on TI‐based approaches are paved. Lastly, we present key open challenges and future direction to augment this problem.
