Scheduling updates from remote sensors is a key task for the internet of things (IoT). In this
context, the mathematical concept of age of information is often used to capture the …

This paper investigates a system with two strategic sources, both being able to update a
given information process at the receiver's end, but doing so independently and …

Mobile crowdsensing (MCS)-enabled data collection can be implemented in a cost-effective,
scalable, and flexible manner. However, joint sensing data freshness and security …

We extend available analytical studies that leverage queueing theory to compute closed-
form expressions for the average AoI in queueing systems with multiple sources …

Performance metrics such as Age of Information are used to represent data freshness, which
is a key element to track in sensing scenarios with sporadic reporting, as typical for ex-ample …

Status update freshness in slotted ALOHA networks is an important issue for Internet of
things scenarios with large number of nodes and uncoordinated access. We compare the …

We analyze a system where a transmitter (Alice) sends status updates to a legitimate
receiver (Bob), but a fraction of them can be captured by an eavesdropper (Eve). Alice is …

We consider a communication system where a base station (BS) transmits update packets to
N users, one user at a time, over a wireless channel. We investigate the age of this status …

We present a game theoretic analysis of a personal e-health system, where a user reports
self-measured data to a collection center. Our focus lies on addressing the challenge of …

Grant-free access, in which each Internet-of-Things (IoT) device delivers its packets through
a randomly selected resource without spending time on handshaking procedures, is a …
