Alocação de recursos para maximização da EE sujeita a restrições de satisfação.

Abstract

Motivated by the growing demand for more efficient use of energy resources in mobile network, in this work, we study the impact of EE metrics in the QoS satisfaction problem presented in [6] which originally had the objective of maximizing the spectral efficiency. We formulate two problems: PMP and PMEE which in their original form are nonlinear. After some algebric manipulations and insertion of new variables and constraints in the problems we converted the PMP and PMEE problems on ILP and MILP, respectively. Through computer simulations, we studied the impact of these new EE metrics on the problem in [6]. We verified that PMEE solution presented the best compromise in relation to the transmitted data rate and power saving when compared the original solution in [6] and PMP.
