Orchestrating UAVs for Prioritized Data Harvesting: A Cross-Layer Optimization Perspective
Bharath Keshavamurthy, Nicolo Michelusi
This work describes the orchestration of a fleet of rotary-wing Unmanned Aerial Vehicles (UAVs) for harvesting prioritized traffic from random distributions of heterogeneous users…
Propagation Measurements and Analyses at 28 GHz via an Autonomous Beam-Steering Platform
Bharath Keshavamurthy, Yaguang Zhang, Christopher R. Anderson +3
This paper details the design of an autonomous alignment and tracking platform to mechanically steer directional horn antennas in a sliding correlator channel sounder setup for 28…
Multiscale Adaptive Scheduling and Path-Planning for Power-Constrained UAV-Relays via SMDPs
Bharath Keshavamurthy, Nicolo Michelusi
We describe the orchestration of a decentralized swarm of rotary-wing UAV-relays, augmenting the coverage and service capabilities of a terrestrial base station. Our goal is to min…
A Robotic Antenna Alignment and Tracking System for Millimeter Wave Propagation Modeling
Bharath Keshavamurthy, Yaguang Zhang, Christopher R. Anderson +3
In this paper, we discuss the design of a sliding-correlator channel sounder for 28 GHz propagation modeling on the NSF POWDER testbed in Salt Lake City, UT. Beam-alignment is mech…
Learning-based Spectrum Sensing and Access in Cognitive Radios via Approximate POMDPs
Bharath Keshavamurthy, Nicolo Michelusi
A novel LEarning-based Spectrum Sensing and Access (LESSA) framework is proposed, wherein a cognitive radio (CR) learns a time-frequency correlation model underlying spectrum occup…
MAESTRO-X: Distributed Orchestration of Rotary-Wing UAV-Relay Swarms
Bharath Keshavamurthy, Matthew Bliss, Nicolò Michelusi
This work details a scalable framework to orchestrate a swarm of rotary-wing UAVs serving as cellular relays to facilitate beyond line-of-sight connectivity and traffic offloading…
