Research on energy saving of computer rooms in Chinese colleges and universities based on IoT and edge computing technology

Studying the impacts of test condition and nonoptimal positioning of the sensors on the accuracy of the in-situ U-value measurement

“…To address this issue, IoT solutions can be employed to facilitate data filtration [ 47 ]. In this context, several IoT-based architectures have been proposed in the literature with various objectives, such as enhancing the reliability and efficiency of data collection processes [ 48 ], analyzing indoor thermal comfort [ 49 ], evaluating energy savings in buildings [ 50 ], studying the influence of transient facades on indoor air quality [ 51 ], and enabling real-time monitoring of energy consumption [ 52 ]. Furthermore, to overcome the high costs associated with commercial monitoring systems [ 53 ], several low-cost methodologies have been suggested.…”

A novel energy-saving method for campus wired and dense WiFi network applying machine learning and idle cycling techniques

“…But IoT and WSN can be used for implementing energy savings in dense WiFi networks using sensors, actuators, and programmable electronic cards. Benhamaid et al (2022) and Qu (2022) proposed routing protocols that reroute network traffic and turn off inactive wireless terminals to increase energy savings (Jimenez et al 2019;Marrero et al 2019;Dhandapani et al 2022). García Baquerizo et al (2019) proposed the use of an Arduino-based electronic circuit to control the dual power supply of WiFi APs: using a traditional via wall socket (alternating current) and a battery (direct current).…”

“…Efficient management of required time communication of data (controlling the bandwidth of the wireless channels) allows to augment energy savings (Qu 2022) by varying transmission power standard parameters. The inconvenience of those techniques is the reduced amount of energy savings FACETS Downloaded from www.facetsjournal.com by 44.224.250.200 on 06/03/24 (10%) compared with the no-application of the technique (Silva et al 2019).…”
