Current low earth orbit (LEO) satellite network display poor power efficiency, running devices at full capacity all the time regardless of traffic matrix and distribution population over Globe. Most research on energy efficiency LEO satellites has focused component level or link level. Therefore, this kind is not holistic to try look system as a single node. To enhance efficiency. The solution ...

Power analysis attacks are based on analyzing the power consumption of the cryptographic devices while they perform the encryption operation. Correlation Power Analysis (CPA) attacks exploit the linear relation between the known power consumption and the predicted power consumption of cryptographic devices to recover keys. It has been one of the effective side channel attacks that threaten the ...

Power consumption is rapidly increased in data centers because the number of data center is increased and more the scale of data center become larger. Therefore, it is one of key research items to reduce power consumption in data center. The peak power of a typical server is around 250 watts. When a server is idle, it continues to use around 60% of the power consumed when in use, though vendors...

This paper proposes a three-step approach to forecasting time series of electricity consumption at different levels household aggregation. These are linked by hierarchical constraints—global is the sum regional consumption, for example. First, benchmark forecasts generated all using generalized additive models. Second, each series, aggregation algorithm ML-Poly, introduced Gaillard, Stoltz, and...
