Network lifetime and energy consumption are major issues in wireless sensor networks
while protection of the primary user is the most important activity in a cognitive radio network …

The Cognitive Radio (CR) technology is an emerging technology in order to solve the
spectrum scarcity problem in the future wireless communication networks. Spectrum sensing …

A Cognitive radio sensor network (CRSN) is characterized as a circulated system of remote
intellectual radio sensor hubs, which sense an occasion flag and cooperatively impart their …

Green communication is the demand of current and future wireless communication. As the
next-generation communication network, cognitive radio network also needs to meet the …

In this paper, we consider a cognitive radio wireless sensor network (CR-WSN), where each
sensor node is equipped with cognitive radio. A typical concern in CR-WSN is energy …

Spectrum sensing is the method used in Cognitive Radio (CR) to find the unused spectrum.
Based on spectrum sensing only other functions of CR can be implemented. So for …

In this paper, spectrum sensing methods analysis and comparison are presented. The
spectrum sensing techniques implementation challenges and issues are discussed in detail …

Eigenvalue based spectrum sensing schemes such as Maximum Minimum Eigenvalue
(MME), Maximum Energy Detection (MED) and Energy with Minimum Eigenvalue (EME) …

An important functionality of cognitive radio network is spectrum sensing. It is performed to
determine the idle frequency bands that are not being occupied by a licensed primary user …

There's a huge demand for spectrum, but in conventional system radio spectrum is
inefficiently used. To overcome this problem and increase array use of spectrum, cognitive …
