Internet of Remote Things: A Communication Scheme for Air-to-Ground Information Dissemination

Data dissemination using Unmanned Aerial Vehicles (UAVs) is currently emerging as an alternative to effectively integrate remote devices to Internet of Things core networks. This paper proposes the use of a closed loop transmission diversity scheme in order to disseminate information toward almost static and battery-limited devices typically unable to communicate over long distances. We present results that show the multiplexing gain that is possible to get in UAV scenarios, which are characterized by the presence of a strong Line-of-Sight (LOS) component. Moreover, we show that in presence of a large amount of users or devices, data separation can be significantly improved by the use of low complexity blind receivers.
