Wireless spectrum sharing via waiting-line auction

We propose a wireless spectrum sharing framework based on waiting-line auction. Our framework includes both spectrum assignment and power allocation; it is designed to maximize the primary user¿s profits as well as to optimize the overall rate under secondary users¿ minimal rate requirements. On secondary users¿ side, it is proved that bidders could achieve equilibrium bids according to Nash equilibrium strategy function, which relate to their valuations for communications. For the primary user, we design a low-complexity auction clearing algorithm that considers both primary user¿s revenue and the system overall rate.
