Resource Slicing for Time-Sensitive Data Traffic in Non-Terrestrial Networks with FSO ISLs
Abid Afridi, Alexis A. Dowhuszko, Risto Wichman +1
In multi-hop Low Earth Orbit (LEO) satellite networks, time-sensitive packets experience queueing across multiple satellite hops, causing per-hop waiting times that accumulate and…
Spatial and Temporal Correlation of Interference in a Narrow Multibeam LEO Satellite Random Access Network
Ilari Angervuori, Abid Afridi, Risto Wichman
Interference is a limiting factor in the emerging dense low Earth orbit (LEO) networks. In the LEO network, the interference is spatially and temporally correlated. At narrow-beam…
Stochastic Analysis of Successive Interference Cancellation in a Narrow-Beam LEO Uplink
Ilari Angervuori, Risto Wichman
This paper investigates uplink coverage probability, i.e., the SIR distribution, and SIR order statistics at a low Earth orbit satellite base station (LEO BS) with narrow Gaussian…
Risk-Aware AoII-Based Scheduling with Hybrid Transmission for a Semi-Markov Source
Saeid Sadeghi Vilni, Risto Wichman
We consider a multi-receiver status update system in which a transmitter monitors a finite-state semi-Markov source and decides whether to stay idle, unicast an update, or broadcas…
Load Balancing in Non-Terrestrial Networks Using Free Space Optical Inter-satellite Links
Abid Afridi, Alexis A. Dowhuszko, Jevgenij Krivochiza +2
Non-terrestrial networks (NTNs) increasingly rely on non-geostationary (NGSO) constellations that combine radio frequency (RF) feeder links (FLs) with free space optical (FSO) inte…
Symbol Rate Maximization in Rolling-Shutter OCC: Design and Implementation Considerations
Xinyu Zhang, Alexis A. Dowhuszko, Miguel Rêgo +4
Optical Camera Communication (OCC) systems can take advantage of the row-by-row scanning process of rolling-shutter cameras to capture the fast variations of light intensity coming…
