With recent advances on the dense low-Earth orbit (LEO) constellation, the LEO satellite
network has become one promising solution for providing global coverage for Internet-of …

Direct-to-satellite Internet of Things (IoT) solutions have attracted a lot of attention from
industry and academia recently, as promising alternatives for large scale coverage of a …

Grant-free (GF) access is a multiple access mechanism being considered for supporting
high user density in massive machine-type communication (mMTC). Since the GF schemes …

Terrestrial and satellite communication networks often rely on two-hop wireless architectures
with an access channel followed by backhaul links. Examples include cloud-radio access …

Long-Range Frequency-Hopping Spread Spectrum (LR-FHSS) has been recently
introduced in the scope of Long Range Wide Area Network (LoRaWAN), aiming at …

This paper considers a low-earth-orbit (LEO) satellite-based topology for an internet-of-
things (IoT) network, where multiple IoT devices broadcast the information to all the visible …

We study the problem of content delivery in two-user interference channels with altering
topology, random available cache at the receivers, and delayed channel knowledge at the …

The impressive increase in market penetration of internet of things (IoT) services and the
