It is expected that the 5G will change the landscape of the communication paradigm as it will offer huge number of device connections, high data rate, evolutionary channel modulation, etc. The 5G predicts to have billions of devices connected through its new scenarios involving Internet of Things (IoT), Machine Type Communications (MTC), Machine- to- Machine Communications (M2M) via the use of different types of devices including but not restricted to smartphones based IP packet.

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.

A B S T R A C TIn the perspective of healthcare, mHealthcare or mobile health care is very important since it has the ability and the feasibility to take care of people's health easier than before. mHealth is a combination of the application on a smartphone that monitors the patient's health and the communication technology that transmits the data of the application to the predefined destination which is the hospital or the doctors. To investigate resource allocation among users in the context of mHealth, different kind of scheduling algorithms have been used to study and analyze the behavior of results taking into consideration diverse scenarios, types of applications and load of the network. Simulation results and a deep analysis were done throughout the article, and they demonstrated interesting conclusions about the combination of all parameters that were studied in this article.
