%X This paper investigated the spectrum sharing based on price dynamics in cognitive radio networks in which one primary service provider sells idle spectrum at different price to secondary service providers, and secondary users dynamically adaped the requested spectrum size according to the received payoffs. In order to maximize the payoffs of secondary uses based on the charging prices all service providers were satisfied,proposed a spectrum sharing approach based on the static and dynamic game. Simulation results indicate that the dynamic game achieves the performance of the static game through setting learning rate properly, and consequently the payoffs of secondary users is maximized.
