Ambient intelligence (AmI) represents the future vision of intelligent computing that can bring
intelligence to our daily life through various domains. In such applications, AmI is often …

We summarize recent contributions in the broad area of age of information (AoI). In
particular, we describe the current state of the art in the design and optimization of low …

In this paper, we introduce a new performance metric in the framework of status updates that
we will refer to as the Age of Incorrect Information (AoII). This new metric deals with the …

Monitoring security and quality of service is essential, due to the rapid growth of the number
of nodes in wireless networks. In healthcare/industrial environments, especially in wireless …

With the advent of 5G technology, the notion of latency got a prominent role in wireless
connectivity, serving as a proxy term for addressing the requirements for real-time …

Freshness of status update packets is essential for enabling services where a destination
needs the most recent measurements of various sensors. In this paper, we study the …

In applications of remote sensing, estimation, and control, timely communication is critical
but not always ensured by high-rate communication. This work proposes decentralized age …

A source provides status updates to monitors through a network with state defined by a
continuous-time finite Markov chain. An age of information (AoI) metric is used to …

In this paper, we introduce the Age of Incorrect Information (AoII) as an enabler for semantics-
empowered communication, a newly advocated communication paradigm centered around …

We consider a Random Access network with a number of nodes transmitting time-sensitive
information to a wireless base station. Packets are generated according to a stochastic …
