Joint UAV Hovering Altitude and Power Control for Space-Air-Ground IoT Networks
TL;DR: A two-stage joint hovering altitude and power control solution for the resource allocation problem in UAV networks considering the inevitable cross-tier interference from space-air-ground heterogeneous networks is proposed.
Full-Duplex Versus Half-Duplex Amplify-and-Forward Relaying: Which is More Energy Efficient in 60-GHz Dual-Hop Indoor Wireless Systems?
TL;DR: A counter-intuitive finding is shown that with a relatively loose maximum transmission power constraint, FD relaying with two-stage self-interference cancellation is preferable to both FD relays with one-stageSelf-Interference cancellation and HD relaying, resulting in a higher optimized EE.

Energy- and Cost-Efficient Physical Layer Security in the Era of IoT: The Role of Interference
TL;DR: This overview of recent interest in energy-efficient and cost-efficient PHY solutions for securing downlink IoT transmission through interference exploitation discusses the concept of CI, and elaborate the fundamental CI signal design that employs the traditionally undesired interference as a constructive element to LUs while ensuring they are destructive to potential Eves.
