Mobile Edge Cloud-Based Industrial Internet of Things: Improving Edge Intelligence With Hierarchical SDN Controllers

The industrial Internet of Things (IIoT), which integrates the key technologies of industrial communication, computing, and control, can implement flexible management and dynamic scheduling for manufacturing resources. To improve the edge intelligence of the IIoT, this article proposes a novel IIoT architecture with a hierarchical control structure in the mobile edge cloud (MEC). Massive remote radio heads (RRHs) are partitioned into several...
