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 …

This article comprehensively surveys the area of age of information (AoI) in the wireless
networks and focuses on categorising and reviewing the current progress on AoI from an …

Most modern large-scale multi-agent systems operate by taking actions based on local data
and cooperate by exchanging information over communication networks. Due to the …

We study a system in which two-state Markov sources send status updates to a common
receiver over a slotted ALOHA random access channel. We characterize the performance of …

We consider the remote estimation of a stochastic piecewise linear signal, observed by a
sensor, at a monitor. The sensor transmits a packet whenever the observed signal's slope …

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 …

Brief Biography: Vishrant Tripathi obtained his PhD from the EECS department at MIT,
working with Prof. Modiano at the Lab for Information and Decision Systems (LIDS). He is …

We study the design of scheduling policies to minimize the monitoring error of a collection of
correlated sources, where only one source can be observed at any given time. We model …

We consider the design of distributed scheduling algorithms that minimize age of information
(AoI) in single-hop wireless networks. The centralized max-weight policy is known to be …

Age of Information, which emerged as a new performance metric to quantify the data
freshness, has drawn increasing interests recently. At wireless-powered network edge, the …
