A framework for spectrum sharing in cognitive radio networks for military applications
Bindu Bharti, Prabhat Thakur, Ghanshyam Kumar Singh · IEEE Potentials · 2021
In this article, the dynamic spectrum accessing techniques-the overlay, underlay, and hybrid spectrum-sharing approaches-are exploited for the military communication. Furthermore, the importance of the energy efficiency of cognitive radio (CR) networks (CRNs) for military applications is discussed. We also emphasize security threats over the physical layer and their mitigation in CRNs. Finally, we explore why the cross-layer design of protocols is preferred for greater energy efficiency and security.
