跨域无人机协同的物理层安全性能分析
Physical Layer Security Performance Analysis of Cross-Domain UAV Collaboration
摘要
Abstract
To address eavesdropping threats in unmanned aerial vehicle(UAV)relay networks under Rayleigh fading channels,a cross-domain UAV collaboration system integrated with half-duplex coop-erative jamming nodes is constructed,and a physical layer security performance analysis method of cross-domain UAV collaboration is proposed.By jointly optimizing relay information forwarding and jamming transmission,the optimal transmission path is dynamically selected based on the criterion of maximizing the link signal-to-interference-plus-noise ratio(SINR),thereby the channel quality differ-ence between legitimate and eavesdropping links are expanded in the cross-domain dimension.On this basis,selection combining(SC)and maximum ratio combining(MRC)diversity techniques are adopted,and closed-form expressions for the system outage probability and intercept probability are derived,to evaluate comprehensively the system performance from both reliability and security dimensions.Simu-lation results show that the addition of the number of relay nodes with MRC technology can reduce the outage probability by approximately one order of magnitude.The deployment of the cooperative jam-ming nodes effectively suppresses eavesdropping,with the intercept probability decreasing by up to 80%when the number of jamming nodes reaches 10.The results verify the significant improvement in the security-reliability trade-off performance achieved by the proposed scheme.关键词
