Spectrum Sharing Algorithm Based on Repeated Game Theory for Cognitive Radios
Dang Jian-wu · Journal of the China Railway Society · 2011
The paper proposes a spectrum sharing algorithm based on the repeated game theory for cognitive radios.The appropriate trigger is adopted to maximize the total rate profit of spectrum sharing and Pareto optimality.Performance analysis and simulation results show that the cooperative strategy for spectrum sharing can get the goal of total profits maximization.Next,the convergence behavior of the spectrum sharing algorithm is investigated in consideration of the impacts of the transmission power,noise power,discount factor and convergence coefficient.Finally,relevant conclusions are drawn.
