Mode Hopping for Anti-Jamming in Radio Vortex Wireless Communications [PDF]
IEEE Transactions on Vehicular Technology, 2018 Frequency hopping (FH) has been widely used as a powerful technique for antijamming in wireless communications. However, as the wireless spectrum is becoming more and more crowded, it is very difficult to achieve efficient antijamming results with FH-based schemes.

Anti-Jamming RIS Communications Using DQN-Based Algorithm
IEEE Access, 2022 Wireless sensor networks (WSNs) are widely applied in battlefield surveillance, where the data collection (e.g. target tracking or contention zone observation) employed by local sensor nodes needs to send to military bases for tactical decisions. Since data transmissions are susceptible to malicious attacks, jammers of adversaries can successfully ...
