Cognitive radio networks are special networks that involve cognitive radio devices for communication. The cognitive networks utilizes network spectrum for communication. The users who are having valid license to access the spectrum are Primary Users (PUs) and other users are Secondary Users (SUs). Utilization spectrum bandwidth is an important concern in cognitive networks. In this paper, a new economic mechanism for better network utilization is proposed including the channel reuse opportunities in order to improve the network performance.
