Cognitive radio (CR) is an emerging technology that enables the flexible development and deployment of highly adaptive radios that are built upon software defined radio technology. These types of networks have applications in dynamic spectrum access, co-existence of different wireless network, interference management, etc. They are touted to drive the next generation of devices, protocol and applications. The cognitive radio network paradigm poses many new technical challenges in protocol design, power efficiency, spectrum management, spectrum detection and distributed spectrum managements. The optimal rule for any detector applied to cooperative spectrum sensing. Keywords—Cognitive radio, energy detection, optimization, spectrum sensing.
