Abstract:

Device-to-Device (D2D) communication has advantages of improving the spectral resource efficiency. But unfortunately, it brings about interference and potential secrecy hazard. In this paper, a Stackelberg game based power control algorithm is provided to enhance the physical layer security underlaying D2D communication by utilizing the interference. Then, a mathematical model based on Stackelberg game is set up, in which we regard the secrecy energy efficiency as the utility function. After that, the existence and uniqueness of the Stackelberg Equilibrium is proved. In addition, a power control algorithm is offered, which can iteratively converge to the Stackelberg Equilibrium. Finally the simulation results show that by applying the provided algorithm, both the cellular user and the D2D pair have the secrecy energy efficiency improved.
