ABOUT LEO-NET

Low Earth Orbit satellite communication has rapidly matured from early deployments to a global-scale industry, with multiple commercial mega-constellations now serving millions of users worldwide. Yet many aspects of their network design and operation remain opaque or poorly understood at scale. The growing complexity of these constellations — spanning direct-to-device connectivity, inter-satellite links, multi-orbit coordination, and terrestrial integration — continues to pose critical open challenges.

LEO-NET 2026 invites submissions from researchers and practitioners in academia and industry who are exploring the latest developments and open challenges in LEO satellite networks and communications. We welcome both regular research papers and work-in-progress or position papers that present new directions, highly original ideas, or have the potential to provoke insightful discussions.

TOPICS OF INTEREST

The scope of this workshop includes (but is not limited to):

- LEO topology and constellation design
- Routing for LEO constellations
- Transport and congestion control for LEO networks
- Resource management for LEO networks
- Content delivery and streaming over LEO networks
- Mobility and handover management in LEO networks
- Inter-satellite links and optical/laser communication
- Integration of LEO with MEO/GEO and terrestrial networks (5G, 6G)
- Direct-to-device (D2D) satellite communication
- Standardization and protocol compliance for non-terrestrial networks
- Computing, edge intelligence, and IoT in space
- ML/AI for LEO networks including onboard inference
- Security, privacy, and cyber resilience for LEO networks
- Sustainability, space policy, and regulatory aspects
- Emerging applications for LEO networks
- Performance measurements, simulation, and emulation tools

SUBMISSION GUIDELINES

Submissions must be original, unpublished work, not currently under consideration elsewhere. Regular research papers of up to 6 pages (excluding references and appendices) in two-column 10pt ACM format. Papers must be double-blind (no author names or affiliations). Authors of accepted submissions are expected to present their work at the workshop.
