In recent years, Low Earth Orbit (LEO) satellite networks, such as Starlink, have seen significant advancements. However, related studies indicate that link quality in Starlink may frequently fluctuate due to events like handovers. Additionally, since Starlink employs a proprietary communication system, existing studies have primarily focused on end-to-end performance evaluation, and thus its route selection methods remain undisclosed. Therefore, this study uses the ns-3 LEO module to simulate current and future Starlink environments and evaluates the impact of satellite selection methods on the communication performance of LEO satellite networks. We propose a new satellite selection method that predicts the orbits of available satellites to extend communication durations. Simulation results showed that the proposed method improved communication duration by up to 114.8% compared to AODV. This study demonstrates that the proposed method can reliably achieve extended communication duration and stable route establishment, even in satellite constellations planned for future configuration.

摘要

In recent years, Low Earth Orbit (LEO) satellite networks, such as Starlink, have seen significant advancements. However, related studies indicate that link quality in Starlink may frequently fluctuate due to events like handovers. Additionally, since Starlink employs a proprietary communication system, existing studies have primarily focused on end-to-end performance evaluation, and thus its route selection methods remain undisclosed. Therefore, this study uses the ns-3 LEO module to simulate current and future Starlink environments and evaluates the impact of satellite selection methods on the communication performance of LEO satellite networks. We propose a new satellite selection method that predicts the orbits of available satellites to extend communication durations. Simulation results showed that the proposed method improved communication duration by up to 114.8% compared to AODV. This study demonstrates that the proposed method can reliably achieve extended communication duration and stable route establishment, even in satellite constellations planned for future configuration.
