Neural networks in the pursuit of invincible counterdrone systems
The growing range of possibilities provided by the proliferation of commercial unmanned aerial vehicles, or drones, raises alarming safety and security threats. The efficient mitigation of these threats depends on authorities having defense systems to counter both accidentally trespassing and maliciously operated drones. To effectively counter such vehicles, defense systems … [Read more...] about Neural networks in the pursuit of invincible counterdrone systems
A framework for spectrum sharing in cognitive radio networks for military applications
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 … [Read more...] about A framework for spectrum sharing in cognitive radio networks for military applications
