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 …

Within a recent line of research, age of information is supported as an alternate network
performance metric with respect to throughput or delay, to evaluate the performance of …

The age of information is a performance metric describing the freshness of updates, and is of
particular interest for remote sensing scenarios involving high number of nodes, as is …

Although grant-based mechanisms have been a predominant approach for wireless access
for years, the additional latency required for initial handshake message exchange and the …

This paper investigates various multi-agent reinforcement learning (MARL) techniques for
designing grant-free random access (RA) schemes suitable for low-complexity, low-power …

As one of the two fundamental types of multiple access, random access has been widely
adopted in various communication networks, and expected to play an increasingly central …

At a density of one million devices per square kilometer, the10's of billions of devices,
objects, and machines that form a massive Internet of things (mIoT) require ubiquitous …

A recent line of analysis discusses the age of information as a better performance metric
than throughput or delay to evaluate the performance of medium access techniques …

This letter analyzes the impact of packet retransmissions on the performance of wireless
random access protocols. In particular, we focus on the effects of two controllable …
