This paper investigates the energy-aware for computing resources of data center for Industrial Internet of Things (IIoT). The IIoT concern becomes one of the tremendous issue due the growing number of devices connected. To accomplish the QoS of IIoT, the data centers must have a guaranteed performance as a backbone of computation resources. Meanwhile, data centers consume much of power to achieve high performance.
Hence, this paper focuses on the simulation of three tiers network as one of candidates of backbone in IIoT. The simulation result shows the data center load attaining a higher value at predefined load server. The total power usage and the total number of tasks enumerated.
