Integrated UAV-Satellite Communication Architecture with NOMA-based Multi-link Connectivity for Secure and Resilient Wireless Networks

This paper proposes an integrated UAV–satellite communication architecture designed to improve wireless connectivity in dynamic, infrastructure-limited, and contested environments. The framework combines UAV relay platforms, satellite communication, LTE links, cloud-based coordination, and NOMA mechanisms to enhance coverage, spectral efficiency, and service continuity. It also addresses security risks such as interception, interference, and communication disruption. The proposed architecture is applicable to tactical communications, emergency response, critical infrastructure protection, and future beyond-5G/6G networks.
