Friendly jamming is a research area that focuses on developing techniques for jamming attackers in wireless communication networks while minimizing interference with legitimate communication. The goal of friendly jamming is to disrupt malicious communication without causing disruption to legitimate communication. This can involve detecting and jamming unauthorized signals, as well as identifying and allowing authorized signals to pass through unimpeded. Friendly jamming techniques can help enhance the security and reliability of wireless communication networks by effectively countering adversarial interference.
