Fig. 2 Overview of energy efficiency approaches.
Results clearly show that, although security features in constrained nodes incur not negligible computational costs (which impair latencies and energy efficiency), the proposed approach always guarantees better performances with respect to the ZigBee IP security architecture.
Illustrative numerical examples show a significant improvement in the CDN energy efficiency using these approaches.
In this section, we analyze the energy efficiency of two approaches (based on [22] and [25]) that exploit the overhearing capabilities of TXs.
Finally, in Figure 12, we show the performance in terms of energy efficiency for the approaches presented in Section 6 when spatial multiplexing is implemented.
Moreover, the paper aims to illustrate how far the actual energy use and generation at Mediterranean universities are from current EU NZEB targets, and also to propose potential energy efficiency strategies for approaching these targets.
With regard to primary goal of SLAV-Reduction and Energy-Reduction approaches which are reducing SLA violations and increasing energy efficiency respectively, SLAV-Reduction approach consumes the highest amount of power (its power efficiency is low) and Energy-Reduction approach acts as contrary.
To improve energy efficiency in HBC, one approach is to utilize a wake-up receiver (WUR).
This article summarises related work undertaken by the EC-funded Research Project TARGETS, which focuses on assessing energy efficiency by a direct approach.
The model is used to prove the energy efficiency of the suggested approach analytically and to evaluate it using a discrete-event simulation.
