Background With the continuous evolution of communication network architecture, network morphology is expanding from traditional wired networks and terrestrial wireless access (such as Wi-Fi) to heterogeneous systems incorporating multi-mode technologies such as satellite internet, short-wave communication, time/frequency division multiple access (TDMA/FDMA), etc. In special geographical areas such as cross-sea areas, plateaus, polar regions, etc., limited by complex terrain constraints, infrastructure starvation, and extreme environmental disturbances, conventional wired/wireless networks face coverage failure risks. It is needed to construct an air-to-ground integrated networking architecture, and service availability and transmission robustness in a special scene are guaranteed through an innovative control mechanism. In such environments, climate variability and geographic uncertainty will lead to dynamic time-varying network topologies (e.g., satellite links are affected by ionospheric scintillation, short wave channels drift with sunlight intensity), and it is difficult for conventional networking schemes to maintain stable connections. Therefore, highly reliable control algorithms with environmental awareness must be designed.
