Selbstbestimmung, Privatheit und Datenschutz We have found that cooperative spectrum sensing is not only advantageous but is also essential to avoid interference with any primary network users. Interference by licensed users becomes a chief concern and issue, which affects primary as well as secondary users leading to restrictions in spectrum

Judith Meinert,Nicole C. Krämer of the Federal Communications Commission (FCC), only 15–85% of the spectrum is being utilized which compels the researcher to develop technologies for opportunistic spectrum utilization. The emerging field of cognitive radio networks (CRN) provides an exciting solution to solve the problem of spect

Judith Meinert,Nicole C. Krämerhe spectral resources allocated to satellite are not fully utilized, whereas terrestrial spectral resources are becoming overutilized day by day. Therefore, it is important to ascertain an efficient way to share the resources of space-based networks with the terrestrial networks. In view of differen

Hairong Yi,Yuqing Zhu,Dongdai Linmalicious users (MU.) transmit an emulated primary signal throughout the spectrum sensing interval of secondary users (SUs) to prevent them from accessing the primary user (PU) spectrum band. The performance of spectrum sensing under PUE attack is studied for two types of energy detectors: conventio
