The gathering of data from household IoT-enabled devices will incur an energy cost and, in this paper, we investigate the impact of different communications technologies and protocols on that cost. As a first step towards energy-efficient design, we have measured the power consumption of several popular wireless interfaces – Bluetooth (Classic and Low Energy), ZigBee, Wi-Fi and 433 MHz module (RF433). We then combine these measurements through the example of a simple domestic stock control application and we show how an energy-efficient communications paradigm can be designed in each case.

This article presents our perspectives of the 5G technologies with two major themes: Green and Soft. By rethinking the Shannon theorem and traditional cell-centric design, network capacity can be significantly increased while network power consumption is steady or even decreased
This paper reports on a study of energy consumption for data storage in data centres. Unlike previous estimates, which have been extrapolations of broad energy usage within the data centre, we take a bottom-up approach. We show that the growth in energy consumption can be mitigated somewhat by adopting a more aggressive policy of data archiving on long-term, low-energy, ?cold? storage; or more ideally purging data of little or no future value.
The next disruptive trend arising from ICT technologies will be a societal phase transition as we move to a fully connected world in which a vast number of machines and devices distributed around the planet collect, store, process and exchange information to enhance our daily lives - The Internet of Things. It has been predicted that the number of such devices could be over 100 billion virtually ...
A recently published report by CEET has identified access networks, not data centres, as a growing & significant threat to the sustainability of services delivered from the cloud. This is because more people are accessing cloud services via wireless networks.
