A fully distributed satisfactory power control for QoS self-provisioning in 5G networks

摘要

In this paper, we address the problem of energy-aware user satisfaction in self-organizing networks. Our main objective is to meet with the users requirements while reducing energy consumption. Accordingly, we aim at seeking satisfaction equilibria, mainly the efficient satisfaction equilibrium (ESE). We first define conditions of existence and uniqueness of ESE. Considering information-theoretic transmission rate based measure, we fully characterize the ESE and prove that, whenever it exists, it is a solution of a linear system. We show that, at the ESE, no player can increase its Quality of Service without degrading the energy performance. Finally, in order to reach the ESE, we propose a fully distributed scheme based on the Banach-Picard algorithm and show, through simulation results, its qualitative properties.
