具有最小安全距离的安全UAV随机网络

Secure UAV Random Networks With Minimum Safety Distance

Jiawei Lyu, Hui-Ming Wang

摘要:

本文从全网络的角度研究了随机无人机网络的物理层安全问题,其中无人机的位置被建模为Mat $\acute{\text{e}}$ rn硬核点过程(MHCPP)来表征无人机之间的最小安全距离,用户和窃听者的位置分别被建模为泊松簇过程和泊松点过程.无人机采用迫零预编码为多个地面用户提供服务,并发射人工噪声以对抗窃听。我们推导出了典型用户的覆盖概率和保密概率的近似表达式,并由此得到了整个网络的保密吞吐量。数值结果表明,解析解能很好地逼近仿真结果.参数的保密性能的影响。

英文摘要:

In this correspondence, we study the physical layer security in a stochastic unmanned aerial vehicles (UAVs) network from a network-wide perspective, where the locations of UAVs are modeled as a Mat$\acute{\text{e}}$rn hard-core point process (MHCPP) to characterize the minimum safety distance between UAVs, and the locations of users and eavesdroppers are modeled as a Poisson cluster process and a Poisson point process, respectively. UAVs adopt zero-forcing precoding to serve multiple ground users and emit artificial noise to combat eavesdropping. We derive the approximations for the coverage probability and secrecy probability of a typical user, with which we derive the secrecy throughput of the whole network. Numerical results show the analytical results can well approximate the simulation results. Impacts of parameters on the secrecy performance are shown.
