REMOTE ENERGY MONITORING AND MANAGEMENT OF ICT INFRASTRUCTURE
An exponentially rising amount
of data available to users.
More data intensive applications.
Higher access speeds.
Higher network core capacity.
ICT equipment is becoming more “energy hungry”, due to:

REMOTE ENERGY MONITORING AND MANAGEMENT OF ICT INFRASTRUCTURE
CONCLUSIONS
Power monitoring and management can and will facilitate energy savings in
modern ICT systems.
Power models are less accurate as software & hardware becomes more
sophisticated.
It is left as future work to intervene to the hardware and remotely
deactivate/activate devices which may be underutilized/needed.
