A Game Theoretic Framework for Distributed Self-Coexistence Among IEEE 802.22 Networks

—The cognitive radio based IEEE 802.22 wireless regional area network (WRAN) is designed to operate in the under–utilized TV bands by detecting and avoiding primary TV transmission bands in a timely manner. Such networks, deployed by competing wireless service providers, would have to selfcoexist by accessing different parts of the available spectrum in a distributed manner. Obviously, the goal of every network is to acquire a clear spectrum chunk free of interference from other IEEE 802.22 networks so as to satisfy the QoS of the services delivered to the end–users. In this paper, we study the distributed WRAN self–coexistence problem from a minority game theoretic perspective. We model the spectrum band switching game where the networks try to minimize their cost in finding a clear band. We propose a mixed strategy that the competing networks must adhere to in order to achieve the Nash equilibrium. Simulation experiments have also been conducted and results corroborate with ...
