Much is being made of the Industrial Internet of Things (IoT) and the associated need for wireless connectivity for industrial sensors. But the networking needs of industrial devices and applications are distinct from the consumer world, with throughput reliability and security high on the list. To accomplish the Quality of Service (QoS) of IIoT, the data centers must have a guaranteed performance as a backbone of computation resources. This paper investigates the throughput-aware sensor nodes for computing resources of data center for Industrial Internet of Things (IIoT). The paper focuses on the simulation of three tiers network as one of candidates of backbone in IIoT.
