摘要:

在无人机辅助数据采集系统中,无人机通过无线电力传输(WPT)对地面终端(GT)进行充电,并通过无线信息传输(WIT)对地面终端进行数据采集。在本文中,我们的目标是通过联合优化无人机的轨迹和传输调度的所有GT最小化所需的时间。这个问题被制定为一个混合整数非线性规划(MINLP),这是很难解决的一般。为此,我们提出了一种基于二分搜索和连续凸优化(SCO)的迭代算法来解决这个问题,仿真结果表明,我们提出的解决方案优于基准算法。

英文摘要:

In unmanned aerial vehicle (UAV)-assisted data collection system, UAVs can be deployed to charge ground terminals (GTs) via wireless power transfer (WPT) and collect data from them via wireless information transmission (WIT). In this paper, we aim to minimize the time required by a UAV via jointly optimizing the trajectory of the UAV and the transmission scheduling for all the GTs. This problem is formulated as a mixed integer nonlinear programming (MINLP) which are difficult to address in general. To this end, we develop an iterative algorithm based on binary search and successive convex optimization (SCO) to solve it. The simulation shows that our proposed solution outperforms the benchmark algorithms.
