Directional Beam-Based Anti-interference Method for UAV Networks

The UAV network is frequently subjected to interference from environmental and human factors due to its exposed operational environment, posing significant threats to its normal functionality. Therefore, to address the critical issue of interference in UAV networks, an anti-interference method based on directional antenna beams for the UAV network is proposed. The variations in the network topology during periods of interference and subsequent anti-interference interventions are analyzed, and the effectiveness of the directional antennabased anti-interference method is verified through continuous time simulations of network performance. The simulation results demonstrate that the packet loss rate of the UAV network in the anti-interference phase is greatly reduced by 50%, and the task arrival rate is increased by 5%. Network performance is fully optimized by directional antennas.
