National Technical University of Ukraine ‘Igor Sikorsky Kyiv Polytechnic Institute’ offers a novel ground-to-air network architecture designed to maintain resilient connectivity in mobile sensor networks. Unlike conventional systems that rely on omnidirectional antennas, the proposed approach leverages directed-action sensors integrated with a multi-level deployment of heterogeneous telecommunication aerial platforms, including both helicopter and aircraft-type UAVs. The presentation will cover the mathematical modeling, optimization methods, and hardware feasibility of this method. We will discuss how hardware modernization using directional antennas can extend the information transmission distance by 3.9–4.6 times or boost data rates by 1.7–3.5 times compared to existing single-level prototype systems. Furthermore, simulation results obtained from Matlab and Atoll environments will illustrate significant improvements across key network criteria, such as end-to-end delay, data transmission speed, and the required number of active aerial platforms. Given the heavy reliance on spatial antenna configuration and algorithmic signal distribution, this research directly interfaces with modern antenna design and advanced signal processing techniques.
