Contribution

It proposes a novel game theoretic approach with a hybrid access mechanism and power control for QoS in HetNets, addressing prioritized access and equilibrium stability.

Findings

Existence of pure strategy Nash equilibrium confirmed.

Scheme increases network capacity and operator revenue.

Effective management of interference and prioritized access.

Abstract

With the proliferation of mobile phone users, interference management is a big concern in this neoteric years. To cope with this problem along with ensuring better Quality of Service (QoS), femtocell plays an imperious preamble in heterogeneous networks (HetNets) for some of its noteworthy characteristics. In this paper, we propose a game theoretic algorithm along with dynamic channel allocation and hybrid access mechanism with self-organizing power control scheme. With a view to resolving prioritized access issue, the concept of primary and secondary users is applied. Existence of pure strategy Nash equilibrium (NE) has been investigated and come to a perfection that our proposed scheme can be adopted both increasing capacity and increasing revenue of operators considering optimal price for consumers.
