UAV-to-UAV Communications

In this section, we investigate the secrecy performance of a UAV-to-UAV system, where a UAV acts as the source (S) transmitting information to a legitimate UAV receiver while a group of UAVs trying to eavesdrop on the information delivery between S and legitimate UAV receiver. The locations of the legitimate UAV receiver and the eavesdropping UAVs are randomly distributed in the coverage space of S. We first characterize the statistical characteristics of the SNR over S to the legitimate UAV receiver links. Then the closed-form analytical expressions for SOP and the average secrecy capacity have also been derived accordingly. Finally, Monte Carlo simulations are carried out to verify our proposed analytical models.
