Abstract
Laser Inter-Satellite Links (ISLs) in Low Earth Orbit (LEO) constellations suffer from high-frequency volatility, causing traditional reactive routing to experience severe route flapping. We present RepuSat, a stability-aware routing framework acting as an algorithmic low-pass filter. By conceptualizing link states as time-evolving reputation scores, it rewards sustained stability and penalizes transient flappers. Simulations show RepuSat reduces latency by up to 49.7% and caps packet loss below 5%, proving that historical reliability outweighs instantaneous capacity.1
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...

Low Earth orbit (LEO) satellite networks require adaptive routing because satellite mobility, inter-satellite link availability, and traffic congestion change over time. This paper proposes a double deep Q-Network-based traffic-aware routing method for dynamic LEO satellite networks. The routing agent selects the next-...

In adversarial electromagnetic environments, unmanned aerial vehicle (UAV) ad hoc networks are highly susceptible to periodic jamming. Because links are repeatedly disrupted and restored, periodic jamming is more challenging than continuous jamming: link-state protocols such as Optimized Link State Routing (OLSR) may u...

Satellite–Terrestrial Integrated Networks (STINs) undergo frequent topology reconfiguration due to the high mobility of satellite nodes, which can disrupt active routing paths across time slot boundaries, increase packet drop, and degrade end-to-end reliability. This paper proposes RR-MPF (Reliable Routing with Markov...
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.

A Robust Space Communication Graph model is constructed, demonstrating that four channels suffice to maintain uninterrupted coverage under single node failure conditions, and that static channel preassignment recovers up to 2.7~hours of telemetry throughput relative to conventional reactive handover schemes.
