Abstract
This report summarizes completed and ongoing work aimed at increasing the capacity of tactical mobile ad hoc networks through the integration of unmanned aerial vehicles (UAVs). Earlier results have been published in separate reports and conference papers; the present document provides a consolidated overview of the work conducted to date and outlines the current way forward. The idea behind the concept is to enhance the capacity of a tactical mobile ground network by employing higher frequency bands (and thereby wider bandwidths) and by introducing low-flying UAVs to maintain network connectivity. The report summarizes the key elements investigated so far, including frequency selection, required numbers of UAVs, potential network architectures, detection ranges, and algorithms for UAV placement and repositioning. No fundamental obstacles to the feasibility of the concept have been identified. However, the work has demonstrated that UAV placement is both more critical to system performance and more complex in realistic terrain than initially anticipated. Current research therefore focuses on evaluating placement methods based on reinforcement learning. An important remaining issue is the assessment of jamming resilience, such an analysis requires a robust placement method for the undisturbed baseline case.
