Jamming attacks refer to malicious activities where an attacker intentionally disrupts wireless communication by transmitting high-power interference signals. These attacks can target various types of wireless communication systems, such as Wi-Fi networks, cellular networks, and radio frequency identification (RFID) systems. The goal of jamming attacks is to interfere with the normal operation of the targeted communication system, leading to denial of service or unauthorized access. Jamming attacks can be executed by sending noise signals or impersonating legitimate devices to disrupt the communication channel. Countermeasures for jamming attacks include signal processing techniques, frequency hopping, power control mechanisms, and physical security measures. Researchers continue to explore new methods to detect and prevent jamming attacks in wireless communication systems.
