Placing smaller cells in a heterogeneous cellular network can be beneficial in
terms of energy because better capacities can be obtained for a given energy
constraint. These type of deployments not only highlight the need for appropriate
metrics to evaluate how well energy is being spent, but also raise important issues
that need to be taken into account when analysing the overall use of energy. In this
work, handoff strategies, bandwidth allocation, and path loss models in different
scenarios, illustrate how energy can be consumed in a more efficient way when
cell size is decreased. A handoff strategy based on per-energy capacity is studied
in order to give priority to a more energy efficient handoff option. Energy can
also be spent more adequately if the transmit power is adjusted as a function of
interference. As a result, users can experience higher capacities while spending less
energy, depending whether they handoff or not, increasing the overall performance
of the network in terms of energy efficiency.
