Rethink Web Service Resilience in Space: A Radiation-Aware and Sustainable Transmission Solution

2026-03-19

AI Summary

This work addresses the vulnerability of web services in low Earth orbit (LEO) satellite networks to space radiation, which induces hardware degradation, battery aging, and service disruptions. Existing mitigation strategies often incur high energy overhead or compromise connection continuity. To overcome these limitations, the paper proposes RALT (Radiation-Aware LEO Transmission), a novel control-plane mechanism that, for the first time, jointly optimizes space weather data with network-layer transmission policies. RALT dynamically reroutes traffic during radiation events while explicitly incorporating energy constraints into its decision-making process. By doing so, it ensures the continuity of real-time services such as WebRTC and substantially reduces radiation-induced battery degradation, thereby achieving a unified balance between service resilience and energy sustainability.

Abstract

Low Earth Orbit (LEO) satellite networks such as Starlink and Project Kuiper are increasingly integrated with cloud infrastructures, forming an important internet backbone for global web services. By extending connectivity to remote regions, oceans, and disaster zones, these networks enable reliable access to applications ranging from real-time WebRTC communication to emergency response portals. Yet the resilience of these web services is threatened by space radiation: it degrades hardware, drains batteries, and disrupts continuity, even if the space-cloud integrated providers use machine learning to analyze space weather and radiation data. Specifically, conventional fixes like altitude adjustments and thermal annealing consume energy; neglecting this energy use results in deep discharge and faster battery aging, whereas sleep modes risk abrupt web session interruptions. Efficient network-layer mitigation remains a critical gap. We propose RALT (Radiation-Aware LEO Transmission), a control-plane solution that dynamically reroutes traffic during radiation events, accounting for energy constraints to minimize battery degradation and sustain service performance. Our work shows that unlocking space-based web services' full potential for global reliable connectivity requires rethinking resilience through the lens of the space environment itself.
