【 摘 要 】

In this paper, a distributed “Win-Win” reciprocal-selection-based medium access scheme (DWWRS-MAS) is designed for a cooperative spectrum leasing system hosting multiple licensed transmission pairs and multiple unlicensed transmission pairs. Based on the proposed DWWRS-MAS, the primary transmitter (PT) intends to lease its spectral resources to an appropriate secondary transmitter (ST) in exchange for cooperative transmission assistance for the sake of minimizing its transmit power and simultaneously satisfying its transmit rate requirement. The ST has an incentive to collaborate with the best PT for the sake of minimizing the ST's transmit power under the constraint of its Quality of Service (QoS) requirement, while simultaneously winning a transmission opportunity for its own traffic. Moreover, based on the matching theory and queueing theory, we analyze the algorithmic stability and the queueing stability of the cooperative spectrum leasing system exploiting our DWWRS-MAS, respectively. Simulation results demonstrate that our DWWRS-MAS is capable of providing both considerable energy savings and substantial rate improvements for the cooperative spectrum leasing system hosting multiple licensed transmission pairs and multiple unlicensed transmission pairs.
