Summary:
In this paper, we investigate the influence of time scales to the evolution of extortioners with cooperators and defectors in homogeneous random networks. When letting strategies's lifetime is related to their fitness, the extortioners are easy to invade the clusters of defectors, and form stable relationship with cooperative neighbors. Therefore, introducing the time scale factor into game dynamics promotes the stable existence of extortioners and furthermore enhances the cooperation level in homogeneous random networks. With the network becomes denser, the frequency of cooperators will decrease monotonically, which is due to the fact that cooperators are easy to meet defectors and be exploited by them.
