  title={UAV Assisted Data Collection for Internet of Things: A Survey}, 
  abstractNote={Thanks to the advantages of flexible deployment and high mobility, unmanned
aerial vehicles (UAVs) have been widely applied in the areas of disaster
management, agricultural plant protection, environment monitoring and so on.
With the development of UAV and sensor technologies, UAV assisted data
collection for Internet of Things (IoT) has attracted increasing attentions. In
this article, the scenarios and key technologies of UAV assisted data
collection are comprehensively reviewed. First, we present the system model
including the network model and mathematical model of UAV assisted data
collection for IoT. Then, we review the key technologies including clustering
of sensors, UAV data collection mode as well as joint path planning and
resource allocation. Finally, the open problems are discussed from the
perspectives of efficient multiple access as well as joint sensing and data
collection. This article hopefully provides some guidelines and insights for
researchers in the area of UAV assisted data collection for IoT.},
