The traffic in cellular networks has been growing at an accelerated rate. In order to meet the rising demand for large data volumes, shrinking the cell size may be the only viable option. In fact, locally deployed small cells, namely picocells and femtocells, will certainly play a major role in meeting the IMT-Advanced requirements for the next generation of cellular networks. Notwithstanding, several...
This paper addresses the interference management problem in the context of LTE-Advanced femtocells. Due to the expected large number of user-deployed cells, centralized network planning becomes increasingly less viable. Consequently, we consider an architecture of autonomous decision makers. Our main contribution in this paper, denominated Generalized Autonomous Component Carrier Selection (G-ACCS),...
Dynamic spectrum approaches are steadily gaining momentum, especially in the context of femtocells. Yet designing efficient, stable, fair and scalable distributed algorithms is no easy feat, specially if the cells in a wireless network tend to act selfish and independently. Game Theory is a powerful toolbox which models the interaction of autonomous agents. In this paper we present a game theoretic...
