The application potential game for dynamic spectrum access in cognitive radio

This paper presents an application of game theory for dynamic spectrum access in cognitive radio. The potential game was analyzed in mesh network which is based on the ortogonal frequency division multiplexing. The gain channel is calculated according to the observed propagation model developed for macro-cells in urban area. The power allocation on the subcarriers was performed by optimizing water-filling algorithm. Simulations of cognitive users access to dynamic spectrum in different time intervals was conducted using MatLab.
