Game theory based spectrum sharing for QoS provisioning in heterogeneous networks

In this fifth generation era, interference management as well as ensuring better Quality of Service (QoS) is an immense concern for the service providing operators. With a view to improving the efficacy and flexibility of mobile communications future generation networks will confide on autonomous and distributed architectures. In this prospect game theory comes up with the hypothetical but ideal framework for modelling efficient and robust algorithms. In this paper, we propose a game theory based algorithm along with self-optimizing power control scheme and thus resolve prioritized access issue with the concept of primary and secondary users being applied. Investigation for the existence of pure strategy Nash equilibrium (NE) has been traversed and in the end we conclude that, our proposed algorithm can be adopted in the modern wireless networks for reduction of interference as well as revenue increment of the service providing operators ensuring optimal price for consumers.
