摘要：
Owing to the high flexibility and adaptability, autonomous aerial vehicle (AAV) ad hoc networks have been regarded as the key technology of low altitude economy communication networks. However, the widespread distribution and multi-hop transmission of AAV ad hoc networks expose them to more serious eavesdropping threats. In this paper, we propose an efficient physical layer security scheme for the AAV ad hoc networks, in which a dual-priority beam matching method is introduced. To prevent data interception, the high-priority signal is buried under low-priority public data. Benefiting from the rich channel diversity among different AAVs in the network, the resource utilization is significantly improved by the proposed beam matching and node selection algorithms. Simulation results show that compared with the conventional physical layer security scheme, the proposed scheme achieves a higher average achievable rate of the low-priority data while guaranteeing the security of the high-priority data, especially in scenarios with limited transmission power and large-scale networks.
