Abstract :
In this paper, we investigate the power allocation for spectrum sharing with constraints of energy consumption in a fixed period. The proposed online power auction is designed according to the pricing discipline of non-cooperative game. Though avoiding abusing energy while interference is great at some time steps, the regret of online power auction (OPA) is acceptable. Numerical results showed that OPA is close to be optimal.
