Abstract

With the rapid development of low-Earth orbit satellite internet, LEO constellation networking and routing optimization algorithms have become research hotspots. The construction of LEO satellite constellation networks faces multiple challenges such as network topology, time delay, and bandwidth. Reasonable routing optimization algorithms can effectively improve the performance and stability of the network. This paper first analyzes the basic structure and characteristics of LEO satellite constellations, then discusses the key factors affecting the networking efficiency of LEO constellations, and proposes a variety of optimization strategies accordingly. Through experiments and simulations, it is verified that the routing optimization algorithm proposed in this paper has significant advantages in improving network throughput, reducing transmission delay, and enhancing service quality. Adopting appropriate networking architectures and routing optimization algorithms can greatly improve the performance of LEO satellite internet, providing strong support for the development of future satellite communication systems.
