论文摘要
我们考虑在共同海拔高度的多个无人驾驶汽车（UAV），该高度是物联网设备网络的数据收集器。首先，使用视觉通道模型的概率线，确定了物联网设备向无人机的最佳分配。接下来，对于大量无人机和/或大型无人机高度的渐近制度，我们为最佳数据速率提出了封闭形式的分析表达式，并表征相应的最佳无人机部署。我们还提出了一种简单的迭代算法，以在高海拔地区找到具有少数无人机的最佳部署。使用粒子群优化发现了全球最佳速率最大化问题的最佳数值解决方案。
We consider multiple unmanned aerial vehicles (UAVs) at a common altitude serving as data collectors to a network of IoT devices. First, using a probabilistic line of sight channel model, the optimal assignment of IoT devices to the UAVs is determined. Next, for the asymptotic regimes of a large number of UAVs and/or large UAV altitudes, we propose closed-form analytical expressions for the optimal data rate and characterize the corresponding optimal UAV deployments. We also propose a simple iterative algorithm to find the optimal deployments with a small number of UAVs at high altitudes. Globally optimal numerical solutions to the general rate maximization problem are found using particle swarm optimization.
