基于能量收集的UAV识别网络中断优化资源分配的低复杂度算法

Low-Complexity Algorithm for Outage Optimal Resource Allocation in Energy Harvesting-Based UAV Identification Networks

Jae Cheol Park, Kyu-Min Kang, Junil Choi

摘要:

研究了一种基于能量采集技术的无人机识别网络。在网络中,无人机通过从地面控制站(GCS)发送的射频(RF)信号获取能量,然后将其识别信息发送到地面接收站(GRS)。具体来说,我们首先推导出中断概率的封闭式表达式来评估网络性能。在此基础上,得到了带宽均匀分配给无人机时的最优时间分配的解析表达式。提出了一种快速收敛的时间和带宽分配算法,以优化基于EH的无人机识别网络的中断性能。仿真结果表明,该算法的性能优于传统的二分法,并达到接近最优的性能。

英文摘要:

We study an unmanned aerial vehicle (UAV) identification network equipped with an energy harvesting (EH) technique. In the network, the UAVs harvest energy through radio frequency (RF) signals transmitted from ground control stations (GCSs) and then transmit their identification information to the ground receiver station (GRS). Specifically, we first derive a closed-form expression of the outage probability to evaluate the network performance. Then we obtain the closed-form expression of the optimal time allocation when the bandwidth is equally allocated to the UAVs. We also propose a fast-converging algorithm for time and the bandwidth allocation, which is necessary for the UAV environment with high mobility, to optimize the outage performance of EH-based UAV identification network. Simulation results show that the proposed algorithm outperforms the conventional bisection algorithm and achieves near-optimal performance.
