Intelligent core network for tactile internet system

Tactile Internet requires a round trip latency of 1ms, which considered being the main challenge with the system realization. Forced by recent development and capabilities of the fifth generation (5G) cellular system, the Tactile Internet will become a real. One way to overcome the 1ms latency is to employ a centralized controller in the core of the network with a global knowledge of the system together with, the concept of network function virtualization (NFV). This is the idea behind the software defined networking (SDN). This paper introduces a Tactile Internet system structure which employs SDN in the core of the cellular network and mobile edge computing (MEC) in multilevels. The system is simulated over a reliable environment and introduces a round trip latency of orders of 1 ms.This can be interpreted by the reduction of intermediate nodes involved in the communication process. © 2017 Association for Computing Machinery
