Toward Tactile Internet Leads with the recent progress and development in the field of robotics and haptic devices, Tactile Internet became the next communication wave after the internet of things (IoT). Far from the traditional Internet in which audio and visual senses can be transferred, Tactile Internet is a new communication paradigm that supports the haptic communications in real time and provides a new way for the humantomachine (H2M) communication. There are many challenges associated with the Tactile Internet, however the 1ms endtoend latency remains the most considerable.In this work, we provide a better understanding of the Tactile Internet system, by defining the main system parameters, components, design requirements and design challenges of the system. We provide the recent progress for realizing Tactile Internet and the main work introduced to provide appropriate solutions for the design issues. A vision of the Tactile Internet system realization and system applications is introduced. Moreover; we investigate the market reflection on Tactile Internet development and realization and a time plan based on the market progress and the academic research is set, to predict away for the Tactile Internet.

A FogBased Architecture for Remote Phobia Treatment Tactile Internet is a next generation Internet. It allows the exchange of haptic sensations in addition to audio and video content. It is a key enabler of several emerging applications as remote robotic surgery and autonomous driving, when combined with 5G and Edge Computing. Because Tactile Internet will enable mission critical applications, it has to adhere to strict requirements, mainly in terms of ultraresponsiveness, ultrareliability and security. In this paper, we propose a fogbased architecture for remote phobia treatment, a Tactile Internet application. The proposed architecture offers a set of software modules that allow a phobia patient to have a therapy session, under the guidance of an expert therapist located remotely, with the patient and the therapist sharing the same virtual reality environment. We use the fog paradigm to meet the stringent Tactile Internet requirements, namely the round trip latency of 1ms. The components of the architecture offer high level interfaces to simplify interaction with external software components as well as with a wide range of hardware devices. A prototype is also implemented and the performance is discussed.
