Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Long‐Term Propagation Measurements in Madrid in a Q‐Band Satellite‐to‐Earth Link
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The Q/V band (40/50 GHz) is gaining interest as satellite operators will need larger bandwidth to be able to provide their services, which are experiencing an increasingly high demand. An accurate characterization of the satellite‐to‐Earth propagation channel is of paramount importance to guarantee a high level of quality of service, by ...

Restoring End‐to‐End Transport With QUIC on Satellite Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Slow Start is a key congestion control mechanism used to assure a safe response to overload of a path across the Internet. This mechanism increases the startup time taken by the sender to reach the capacity available across the path. The benefit becomes significant on paths with a high bandwidth‐delay product.

Uncertainty Characterization Framework for Machine Learning Based ACM in Q‐Band Satellite Links
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Adaptive coding and modulation (ACM) is a widely utilized technique in satellite communication networks to mitigate the adverse effects of rain fades, particularly in extremely high frequency (EHF) bands. As a core component of fade mitigation techniques (FMTs), ACM improves signal resilience.

Science Education, EarlyView.ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...
