Ultra-Reliable Device-Centric Uplink Communications in Airborne Networks: A Spatiotemporal Analysis

This paper proposes an ultra-reliable device-centric uplink (URDC-UL) communication scheme for airborne networks. In particular, base stations (BSs) are mounted on unmanned aerial vehicles (UAVs) that travel to schedule UL transmissions and collect data from devices. To attain unified performance, the connection is established when UAV-BS hovering at nearest possible distance scheduled device. The performance of proposed URDC-UL benchmarked against a stationary UAV-centric (SUC-UL) where devices communicate UAV-BSs continuously static locations. Utilizing stochastic geometry queueing theory, novel spatiotemporal mathematical models developed, which account spatial densities, mobility, altitude, antenna directivity, ground-to-air channel, temporal traffic, among other factors. results demonstrate sensitivity ratio between traveling time. time should be carefully adjusted maximize harvested gains in terms link reliability, transmission rate, energy efficiency, delay. Exploiting allows IoT minimize power while maintaining reliable transmission. preserves device's battery addresses critical design challenge.
