Satisfaction-Based Decentralized Interference Mitigation in Two-Tier Wireless Networks Using Equilibria

In this paper the problem of interference mitigation in ultra dense heterogeneous cellular networks is considered, with the aim to maximize the satisfaction of users. Several game-theoretic approaches based on correlated equilibrium (CE) and satisfaction equilibrium (SE) are compared. Moreover, a new solution based on cooperative approach using CE and satisfaction-based optimization is proposed. Presented simulation results of an ultra dense 5G wireless system show, that the proposed scheme outperforms other solutions in terms of throughput satisfaction.
