This paper introduces the Adaptive Multi-Layered Non-Terrestrial Network (AMLT-NTN), an architecture that integrates satellite, High Altitude Platform Stations (HAPS), and Unmanned Aerial Vehicles (UAVs). It leverages a combination of Free-Space Optical (FSO) and Radio Frequency (RF) communications, tailored for specific operational altitudes to enhance connectivity in remote and disaster-stricken regions. The AMLT-NTN tackles the complexities of dynamic power allocation and link selection by incorporating real-time optimization algorithms. This significantly boosted the network's robustness and adaptability to environmental challenges and demand fluctuations. Simulations in OMNeT++ highlighted a quantifiable enhancement, with up to a 30% increase in throughput and a 40% decrease in latency, outstripping conventional NTN. The AMLT-NTN architecture demonstrates unparalleled resilience, consistently delivering high service levels across various conditions. Looking ahead, this research paves the way for integrating emerging communication technologies and scaling the architecture for widespread adoption. The proposed AMLT-NTN offers transformative solutions for rural connectivity and rapid disaster response, thus poised to impact global digital inclusion.
