Incentive Compatible Mode Selection and Spectrum Partitioning in Overlay D2D-Enabled Network

With the large expected demand of wireless network communication, Device-to-Device (D2D) communication has been proposed as a promising technology to enhance network performance. The selfish nature of potential D2D users, may impale the performance of D2D-enabled network. In this paper, we consider a D2D-enabled cellular network framework, which supports both divided and shared D2D modes, under overlay D2D communication. The framework provides a pricing-based Stackelberg game for optimal mode selection and spectrum partitioning. We propose the incentive compatible pricing strategy to provide proper incentive for these selfish potential D2D pairs to make optimal choices in mode selection. Our results show that the pricing and spectrum partition strategy effectively prevents selfish potential D2D users from harming the system performance while fully exploits the potential of D2D communication.
