Abstract

The large amount of data amongst billions of devices deployed for Industrial Internet of Things (IIoT) cause a massive energy consumption. Driven by the pursuit of green communication, this paper presents a space-reserved cooperative caching scheme for IIoT in the 5th generation (5G) mobile heterogeneous networks, where the cache space in a base station (BS) is divided into two parts, one is used to store the prefetched data (PFD) from the servers ahead of the device request time and the other is reserved to store the temporarily buffering data (TBD) in the wireless transmission queue at the device request time. With the constraint that the quality of service is guaranteed, we propose an algorithm to obtain the optimal proportion between the two partsofthecachingspaceforthepurposeofreducingtheaverage energyconsumption.Simulationresultsveriﬁedthattheproposed caching scheme is more efﬁcient than the conventional one with respect to the average energy consumption.
