In the context of increasing demands for home delivery fresh food, this article addresses terminal distribution problem in an urban environment, which is called vehicle routing probl...

In this article, we investigate multiple unmanned aerial vehicles (UAVs)-enabled data collection system in Internet of Things (IoT) networks with time windows, where rotary-wing UAVs are dispatched to collect from time-constrained terrestrial IoT devices. We aim jointly minimize the number and total operation by optimizing UAV trajectory hovering location. To end, an optimization problem is for...
