论文摘要
本文讨论了确保多个地面用户的传输的问题，以免窃听攻击。我们提出并优化了单个无人驾驶汽车（UAV）的部署，该航空车是用户群和基站之间的空中继电器。重点是通过共同优化地面用户的上行链路传输功能和无人机的位置来最大化保密的能源效率。关节优化问题是非convex；因此，我们将其分为两个子问题，并使用迭代算法解决它们。
This paper discusses the problem of securing the transmissions of multiple ground users against eavesdropping attacks. We propose and optimize the deployment of a single unmanned aerial vehicle (UAV), which serves as an aerial relay between the user cluster and the base station. The focus is on maximizing the secrecy energy efficiency by jointly optimizing the uplink transmission powers of the ground users and the position of the UAV. The joint optimization problem is nonconvex; therefore we split it into two subproblems and solve them using an iterative algorithm.
