Fig. 1From: Mobility-aware hierarchical fog computing framework for Industrial Internet of Things (IIoT)System architecture – IIoT sensors and devices offload tasks via a wireless link between devices and fog nodes. The fog nodes are placed in a hierarchical model classified into multiple levels. Level-1 fog nodes are the intelligent nodes that decide whether to offload tasks to volunteer devices, same-level fog, higher-level fog, or a nearby fog locationBack to article page
