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-latency cyberphysical systems and applications in which sources send time-s

With the emergence of real-time cyberphysical systems, status updates are becoming an important form of communication. Vehicular messaging, security reports from homes and offices, surveillance video, and video feedback from remote-controlled systems

This letter studies the “age of information” (AoI) in a multi-source status update system where $N$ active sources each send updates of their time-varying process to a monitor through a server with packet delivery errors. We analyze the average A

This paper studies the "age of information" in a general multi-source multi-hop wireless network with explicit channel contention. Specifically, the scenario considered in this paper assumes that each node in the network is both a source and a monito

This paper considers the problem of tracking and predicting dynamical processes with model switching. The classical approach to this problem has been to use an interacting multiple model (IMM) which uses multiple Kalman filters and an auxiliary syste

This paper considers the problem of tracking and predicting the state of a dynamic system with stochastic dynamics and multiple modes of operation. A well-known approach to this problem is the "interacting multiple model" (IMM) estimator, which uses

This paper develops a joint coding and modulation scheme for end-to-end communication system design using an autoencoder architecture in the ultra-short blocklength regime. Unlike the classical approach of separately designing error correction codes

We consider the problem of optimal precoder design for a multi-input single-output wideband wireless system to maximize two different figures of merit: the total communication capacity and the total received power, subject to individual power constra

This paper considers the problem of achieving global channel knowledge throughout a fully connected packetized wireless network with time-varying channels. While the value of channel state information at the transmitter (CSIT) is now well known, ther
