摘要:

无人机(UAV)或无人机越来越多地用于交通监控和建筑勘测等城市应用。自主导航允许无人机访问航点并完成任务的一部分。一个常见的活动是悬停和观察一个位置使用机载相机。深度神经网络(DNN)的进步允许对此类视频进行分析,以进行自动决策。无人机还拥有边缘计算能力,用于通过这种DNN进行机载推理。为此,对于一支无人机机队,我们提出了一种新的任务调度问题(MSP),该问题共同调度飞行路线,以访问和记录航点处的视频,以及随后的机载边缘分析。建议的时间表最大限度地提高效用的活动,同时满足活动的最后期限,以及能源和计算的限制。我们首先证明了MSP是NP-困难的,然后通过制定一个混合整数线性规划(MILP)问题最优解决它。接下来,我们设计了两个有效的启发式算法,JSC和VRC,提供快速的次优解。使用真实无人机跟踪对这三个服务器进行的评估展示了不同工作负载下的实用程序-运行时权衡。

英文摘要:

Unmanned Aerial Vehicles (UAVs) or drones are increasingly used for urban applications like traffic monitoring and construction surveys. Autonomous navigation allows drones to visit waypoints and accomplish activities as part of their mission. A common activity is to hover and observe a location using on-board cameras. Advances in Deep Neural Networks (DNNs) allow such videos to be analyzed for automated decision making. UAVs also host edge computing capability for on-board inferencing by such DNNs. To this end, for a fleet of drones, we propose a novel Mission Scheduling Problem (MSP) that co-schedules the flight routes to visit and record video at waypoints, and their subsequent on-board edge analytics. The proposed schedule maximizes the utility from the activities while meeting activity deadlines as well as energy and computing constraints. We first prove that MSP is NP-hard and then optimally solve it by formulating a mixed integer linear programming (MILP) problem. Next, we design two efficient heuristic algorithms, JSC and VRC, that provide fast sub-optimal solutions. Evaluation of these three schedulers using real drone traces demonstrate utility-runtime trade-offs under diverse workloads.
