“…For instance, the input data size is a major driver behind the computation workload [37,39]; the energy incurred by accessing activities mainly depends on the data length [60]; and the amount of data to be transmitted is one of the discriminating factors for communication energy cost [62,45,58]. In the context of communication, the relevant studies further distinguish between two scenes: The first is on the traffic volumes exchanged between the client and the Cloud [40,1,50,51,68,66,42,75,31,81,67,43,49,29,70], while the second is on the data segments involved in, and transferred between, individual application tasks [73,57,64,41,74,2,69]. 3) Transactional Data Size: Although the required energy increases proportionally to the overall data size, small-data transactions in a Cloud application show a negative correlation with the energy consumption.…”
