The Research paper presents an in‐depth survey of state-of-the-art proposals having tactile internet as a backbone for delay mitigation using 5G networks for future ultra‐reliable low‐latency applications such as Healthcare 4.0, Industry 4.0, virtual reality and augmented reality and smart education. From the existing proposals, it has been observed that tactile internet can provide interactions between virtual objects to give a feel of the real environment with maximum latency of 1 millisecond. Also, this paper highlights the key differences between the tactile internet and Internet of Things in context with 5G revolution. Then open issues and challenges of tactile internet for smart applications are analyzed. Finally, a comparison of existing proposals with respect to various parameters is presented, which allows the end-users to select one of the proposals in comparison with its merits over the others.

The Introduction of the paper, provides deep state of the art facts and figures of 5G Communictions.

The Overall flow and structure is awesome, and till date most comprehensive presentation is provided.
