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 …

Communication systems to date primarily aim at reliably communicating bit sequences.
Such an approach provides efficient engineering designs that are agnostic to the meanings …

The restless multi-armed bandit problem is a paradigmatic modeling framework for optimal
dynamic priority allocation in stochastic models of wide-ranging applications that has been …

In this paper, we study a real-time monitoring system in which multiple source nodes are
responsible for sending update packets to a common destination node in order to maintain …

The effective operation of time-critical Internet of things (IoT) applications requires real-time
reporting of fresh status information of underlying physical processes. In this paper, a real …

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 …

In this paper, we investigate a network where N links contend for the channel using the well-
known carrier sense multiple access scheme. By leveraging the notion of stochastic hybrid …

Age of information (AoI) is a performance metric that measures the timeliness and freshness
of information, and is particularly relevant in applications with time-sensitive data. This paper …

In this article, we consider the average age minimization problem where a central entity
schedules M users among the N available users for transmission over unreliable channels. It …

Information freshness is crucial for time-critical IoT applications, eg, monitoring and control.
We consider an IoT status update system with users, energy harvesting sensors, and a …
