Towards Tactile Internet in Beyond 5G Era: Recent Advances, Current Issues and Future Directions
Tactile Internet (TI) is envisioned to create a paradigm shift from the
content-oriented communications to steer/control-based communications by
enabling real-time transmission of haptic information (i.e., touch, actuation,
motion, vibration, surface texture) over Internet in addition to the
conventional audiovisual and data traffics. This emerging TI technology is
expected to create numerous opportunities for technology markets in a wide
variety of applications ranging from teleoperation systems and AR/VR to
automotive safety and eHealthcare towards addressing the complex problems of
human society. However, the realization of TI over wireless media in the
upcoming 5G and beyond networks creates various non-conventional communication
challenges and stringent requirements. To this end, this paper aims to provide
a holistic view on wireless TI along with a thorough review of the existing
literature, to identify and analyze the involved technical issues, to highlight
potential solutions and to propose future research directions. First, starting
with the vision of TI and recent advances and a review of related
survey/overview articles, we present a generalized framework for wireless TI in
the Beyond 5G Era including a TI architecture, main technical requirements, key
application areas and potential enabling technologies. Subsequently, we provide
a comprehensive review of the existing TI works by broadly categorizing them
into three main paradigms; namely, haptic communications, wireless AR/VR, and
autonomous, intelligent and cooperative mobility systems. Next, potential
enabling technologies across physical/MAC and network layers are identified and
discussed in detail. Also, security and privacy issues of TI applications are
discussed along with some promising enablers. Finally, we present some open
research challenges and recommend promising future research directions.Comment: 40 pages, 4 figures, 8 tables, submitted to IEEE Journa
