In this paper, we study the joint price and power allocation in spectrum sharing macro-femtocell networks. The proposed game theoretic framework is based on bi-level Stackelberg game where macro base station (MBS) works as a leader and underlaid femto base stations (FBSs) work as followers. MBS has fixed data rate and imposes interference price on FBSs for maintaining its data rate and earns revenue...
Two-tier femtocell network is considered a promising solution for the rapidly rising mobile data rate demand due to its high spectrum efficiency. However, underlaying femtocells with macrocells will result in co-channel interference (CCI) which severely deteriorates network performance. Therefore, optimized power control is required in femtocell network to avoid such interference. Additionally, energy...
