Popis
Shrnutí:Fog computing is one of the promising technology that could reduce the execution cost and energy consumption of smart IIoT devices via offloading. However, designing an intelligent offloading strategy for large-scale industrial applications becomes challenging. To address this issue, we design a novel fog federation, a computation offloading framework for industrial networks called CeCO, where a master fog controller regulates the network and distributes the IIoT data among the fog devices. In particular, we design cost optimization function as the sum of weighted energy-delay cost of devices while reaching several constraints. To determine this optimization problem, we first design a frequency control mechanism for IIoT devices. Then we introduce a controller-based device adaptation strategy and a policy-based Reinforcement Learning technique for efficiently controlling emergency-based service demands and accordingly route to devices following the shortest path. Experimental results demonstrate the effectiveness of the CeCO strategy as compared to the baseline algorithms.
