| Summary: | Tactile Internet is considered as the next step towards a revolutionary impact on the society, this is due to the introduction of different types of applications mainly the haptic ones that require strict Quality of Service guarantee especially in terms of latency. This would be a major challenge towards the design of new communication technologies and protocols in order to provide ultra-low latency. This article discusses the diverse technologies, communication protocols, and the necessary infrastructure to provide low latency based principally on the fifth generation (5G) of mobile network that is considered as the key enablers of the Tactile Internet. Furthermore, current research direction along with future challenges and open issues are discussed extensively.
