Energy Optimisation for Mobile Device Power Consumption: A Survey and a Unified View of Modelling for a Comprehensive Network Simulation

The need for the analysis of energy consumption
has become greater due to the constrained resources of
mobile devices afforded by the increased usage of mobile
devices and the environmental footprint of large-scale, distributed
systems. Energy usage has previously been modelled
for a variety of use cases in order to optimise its
consumption, through both simulation and real-world use.
As computing devices become ubiquitous,moremobile, and
highly varied in their components and use; the networks
which interconnect them have become highly dynamic in
tandem. This is partly due to the mobility of devices and the
constantly fluctuating resource requirements. Whilst simulation
of energy consumption within networks has been
conducted for specific use cases (e.g. Cloud and wireless
networks), it is often not examined from a unified view.
This paper attempts to review the state-of-the-art in network
energy consumption, modelling, and simulation from
the perspective of heterogeneous networks but with a focus
upon mobile devices, and then propose a gap in which a unified
view is needed. Such views will assist in understanding
more about the complex relationships between varied, synergistic
device types, such as those which compose mobile
cloud networks.
