چکیده مقاله:
The problem of resource allocation in a spectrum leasing scenario in Cooperative Cognitive Radio Networks (CCRN) is addressed, in this work. The system model consists ofa number of primary user (PU) pairs and a secondary user (SU) pair. We propose a solution for resource allocation problem inthe spectrum leasing scenario. More specifically, we determine when is beneficial for a PU to lease its unused spectrum portion to SU and how much of PU’s resource is optimum to be leased.The SU is supposed to cooperate with PUs by relaying the PUs’ signals, in return. Besides, the optimum allocated cooperatingpower of SU to relay each PU’s signals is determined. An efficient auction mechanism is proposed and the existence of the NashEquilibrium (NE) for the proposed auction game is proved
