Multi-Agent Reinforcement Learning-Based Resource Allocation Scheme for UAV-Assisted Internet of Remote Things Systems

IEEE ACCESS, 11, 53155–53164.

By: D. Lee n, Y. Sun *, S. Kim *, J. Kim *, Y. Shin *, D. Kim *, J. Kim *

author keywords: Deep learning; IoRT; multi-agent reinforcement learning; neural episodic control; resource allocation
TL;DR: A multi-agent reinforcement learning (MARL)-based resource allocation scheme for UAV-assisted Internet of remote things (IoRT) systems and the effects from the hyperparameters of the neural episodic control (NEC) baseline algorithm are investigated in terms of power consumption.

Rank and Condition Number Analysis for UAV MIMO Channels Using Ray Tracing

2023 IEEE 97TH VEHICULAR TECHNOLOGY CONFERENCE, VTC2023-SPRING.

By: D. Lee n & I. Guvenc n 

author keywords: AERPAW; condition number; drone; MIMO; channel rank; ray tracing; spatial multiplexing; UAV
TL;DR: Detailed ray tracing simulations are used to characterize how the channel rank tends to reduce as a function of UAV altitude, while also providing insights into the effects of geography, building distribution, and threshold parameters on channel rank and condition number.
