TL;DR
For distributed link-state deployments on stable inclined-shell topologies, these results show that area division is a principled, geometry-driven design choice; they do not claim that PBAR supersedes centralized or geographic routing.
The rapid deployment of Low Earth Orbit (LEO) mega-constellations introduces challenges such as dynamic topology changes, congestion, and routing instability. Continuous orbital motion causes frequent inter-satellite link variations, reducing the effectiveness of traditional reactive routing protocols. This paper propo...
Inter-satellite links constitute a critical enabler for the autonomous operation of global navigation satellite systems (GNSSs).Nevertheless, onboard routing still poses substantial challenges, stemming from the frequent topology variations of GNSS constellations and the constraint of limited onboard computational reso...
In this paper, we propose a window-aware access and routing coordination (WA-ARC) approach for beam-hopping (BH) low-Earth-orbit (LEO) satellite networks. We formulate the joint BH access and routing design as a causal stochastic network optimization problem. To address this problem, we develop a Lyapunov drift-plus-pe...
Although Low Earth Orbit (LEO) megaconstellations offer diverse initial access choices via multisatellite coverage, uneven spatiotemporal traffic frequently causes MAC-layer collisions and physical-layer disconnections. To address this, we propose an intelligent cross-layer initial access algorithm using dynamic compre...
Accurate topology awareness of non-cooperative low Earth orbit (LEO) satellite constellations faces two major challenges: limited ground observation resources and the unavailability of internal node cooperation. To address these issues, this paper proposes a two-stage framework that jointly identifies physical topology...
This work proposes a joint Medium Access Control and Network layer design, centered on a distributed Table-Based (TB) routing protocol that removes control-plane signaling by leveraging only user-plane data transmissions for route discovery and maintenance, and extends TB with a decentralized Multi-Agent Deep Reinforce...
