A Survey of Key Issues in UAV Data Collection in the Internet of Things

Data collection, as the most basic task of Internet of Things (IoT), is an important research topic. Considering the large-scale wireless sensor networks (WSN) deployed in complex geographical environments, Unmanned Aerial Vehicle (UAV)aided data collection, where UAVs are dispatched to collect data. Although UAV-aided data collection overcomes the limitations of data collection in complex geographic environments, there are still some key issues that need to be addressed. In this paper, we will introduce the key technologies of UAV-aided data collection in IoT in detail and propose our ideas.
