In the practical application of cognitive radio network, it is especially important to improve the energy efficiency for those energy-constrained cognitive users. From the perspective of maximizing the energy efficiency in cognitive radio networks, this paper considers the case that the sudden appearance of the primary user can lead to data collision when the cognitive user is transmitting data. Then...
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...
