Joint management of energy consumption, maintenance costs and user revenues in cellular networks with sleep modes
We target the maximization of the operator profitability in a LTE cellular network with e-NodeBs (eNBs) exploiting Sleep Mode (SM) power states. The profitability is composed of different terms, namely: the electricity bill due to the eNBs energy consumption, the maintenance costs due to the application of power states to the eNBs, and the revenues from providing a given throughput to users. After showing that all these components are strictly interdependent, we formulate the problem of maximizing the profitability for a set of eNBs.
