Energy Aware Trajectory Optimization for Aerial Base Stations

Trajectory Optimization for Target Localization Using Small Unmanned Aerial Vehicles

Small unmanned aerial vehicles (UAVs) equipped with navigation and video capabilities can be used to perform target localization. Combining UAV state estimates with image data leads to bearing measurements of the target that can be processed to determine its position. This 3-D bearings-only estimation problem is nonlinear and traditional filtering methods are prone to biases, noisy estimates, a...

Submodular Trajectory Optimization for Aerial 3D Scanning Supplementary Material

In this section, we describe our high-level strategy for data acquisition, as well as our multi-view stereo processing pipeline for estimating the scene geometry and free space. Our goals in this section are twofold. First, we would like to obtain a rough estimate of the scene geometry, in the form of a triangle mesh in real-world coordinates. Second, we would like to obtain a strictly conserva...

Green Energy and Delay Aware Downlink Power Control and User Association for Off-Grid Solar Powered Base Stations

Cellular base stations (BSs) powered by renewable energy like solar power have emerged as a promising solution to address the issues of reducing the carbon footprint of the telecom industry as well as the operational cost associated with powering the BSs. This paper considers a network of off-grid solar powered BSs and addresses two key challenges while operating them (a) avoiding energy outage...

Energy-Efficient Assignment of User Equipment to Cooperative Base Stations

Future radio access networks (RANs) will activate and deactivate base stations (BSs) depending on the activity of users to conserve energy. Reducing the fraction of time a BS is enabled will reduce the energy consumption of the RAN. Using cooperative transmissions from BSs allows to reach user equipment (UE) that is not in range of any single BS. When some BSs cooperate, other BSs can be deacti...
