TL;DR

This paper introduces a Cross-Layer Descent approach to improve the resilience and latency of network operations in proliferated LEO satellite mega-constellations, supporting timely and reliable space communications.

Contribution

It proposes a novel multi-layer networking scheme called Cross-Layer Descent (CLD) that enhances LEO satellite network resilience and timing performance for CCSDS-compliant telecommand transmissions.

Findings

CLD outperforms classical schemes in resilience.

CLD reduces latency in telecommand missions.

Simulation results validate the effectiveness of CLD.

Abstract

With the proliferated low-Earth-orbit (LEO) satellites in mega-constellations, the future Internet will be able to reach any place on Earth, providing high-quality services to everyone. However, high-quality operations in terms of timeliness and resilience are lacking in the current solutions. This paper proposes a multi-layer networking approach called "Cross-Layer Descent (CLD)". Based on the proposed system model, principles, and measures, CLD can support foundational services such as telecommand (TC) transmissions for various network operation missions for LEO satellites compliant with the Consultative Committee for Space Data Systems (CCSDS) standards. The CLD approach enhances timing and resilience requirements using advanced communication payloads. From the simulation-based analysis, the proposed scheme outperforms other classical ones in resilience and latency for typical TC missions. The future work and conclusive remarks are discussed at the end.
