Abstract

This paper presents a novel three-dimensional traffic distribution model aimed at enhancing the analysis and design of Low Earth Orbit Satellite (LEOS) communication systems. The model incorporates both spatial and temporal variations in user traffic, offering a more realistic view of demand by integrating factors such as geography, population distribution, and socio-economic conditions. Unlike traditional models that often assume uniform traffic patterns, this approach captures the dynamic and nonuniform nature of real-world user behavior. The study investigates how this uneven traffic distribution influences key performance indicators, including signal quality, system capacity, and communication latency. Through detailed simulations, the findings reveal that traffic hotspots and underutilized areas can lead to inefficiencies, highlighting the need for advanced resource allocation and scheduling techniques. The proposed model provides valuable insights for improving network planning, ensuring optimal coverage, reducing congestion, and increasing the overall resilience and adaptability of LEOS-based networks in complex, dynamic operational environments.
