The recently introduced 5G New Radio is the first wireless standard natively designed to
support critical and massive machine type communications (MTC). However, it is already …

The study of ad hoc networks and their different varieties, including wireless sensor
networks, wireless mesh networks, and mobile ad hoc networks, is discussed in this paper …

The society as a whole, and many vertical sectors in particular, is becoming increasingly
digitalized. Machine Type Communication (MTC), encompassing its massive and critical …

Age of information (AoI) is gaining attention as a valuable performance metric for many IoT
systems, in which a large number of devices report time-stamped updates to a central …

Unsourced random-access (U-RA) is a type of grant-free random access with a virtually
unlimited number of users, of which only a certain number K a are active on the same time …

This short paper proposes the use of modern random access for IoT applications in 6G. A
short overview of recent advances in uncoordinated medium access is provided …

To account for the massive uncoordinated random access scenario, which is relevant for the
Internet of Things, Polyanskiy et al.(2017) proposed a novel formulation of the multiple …

Low-power wide-area networks (LPWANs) are wireless connectivity solutions for Internet-of-
Things applications, including industrial automation. Among the several LPWAN …

In next generation Internet-of-Things, the overhead introduced by grant-based multiple
access protocols may engulf the access network as a consequence of the unprecedented …

We study the dynamic behavior of frameless ALOHA, both in terms of throughput and age of
information (AoI). In particular, differently from previous studies, our analysis accounts for the …
