What is it about?
We study a green-energy-powered cognitive radio network (GCRN) in an underlay paradigm, wherein multiple battery-free secondary users (SUs) capture both the spectrum and the energy of primary users (PUs) to communicate with an access point (AP). In this way, both energy efficiency and spectrum efficiency can be enhanced.

Why is it important?
Specific scarcity and energy efficiency are always challenges for wireless networks. Thus we study a green paradigm to enhance both energy efficiency and spectrum efficiency.
Perspectives
Very hot topic about green cognitive radio networks, where both energy efficiency and spectrum efficiency can be enhanced.
