The rise of machine-to-machine communications has rekindled interest in random access
protocols as a support for a massive number of uncoordinatedly transmitting devices. The …

Various applications of wireless Machine-to-Machine (M2M) communications have
rekindled the research interest in random access protocols, suitable to support a large …

This paper proposes a new medium access control (MAC) protocol for Internet of Things
(IoT) applications incorporating pure ALOHA with power domain non-orthogonal multiple …

We propose a novel random access (RA) scheme with the quality of service (QoS)
guarantees for machine-to-machine (M2M) communications. We consider a slotted …

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 …

In this paper, we focus on the optimal problem of average age of information (AAoI) in grant-
free massive access, and propose an age-critical frameless ALOHA (ACFA) random access …

Machine-to-Machine (M2M) communications are one of the major drivers of the cellular
network evolution towards 5G systems. One of the key challenges is on how to provide …

The random access methods used for support of machine‐to‐machine, also referred to as
Machine‐Type Communications, in current cellular standards are derivatives of traditional …

In this article, we develop a probabilistic framework for analyzing coded random access. Our
framework is based on a new abstract receiver (decoder), called a Poisson receiver, that is …

Future generation wireless technologies are expected to serve an increasingly dense and
dynamic population of users that generate short bundles of information to be transferred …
