Abstract
In this paper, an improved game-theoretic spectrum sharing algorithm is proposed. Besides considering the available bandwidth, a reliance factor that represents how the primary users would like to lease the free spectrum to secondary users is introduced and the battery capacity of secondary users is taken into account. The simulation results show that the shared spectrum is in direct proportion to the reliance and battery capacity. The existence and uniqueness of Nash equilibrium are proved.
