We consider a setting where multiple active sources send real-time updates over a single-
hop wireless broadcast network to a monitoring station. Our goal is to design a scheduling …

Age of Information (AoI) is an application layer performance metric that quantifies the
freshness of information. This paper investigates scheduling problems at network edge …

This paper proposes using the uncertainty of information (UoI), measured by Shannon's
entropy, as a metric for information freshness. We consider a system in which a central …

We consider a system consisting of multiple sensors, a central monitoring station, and
multiple orthogonal frequency channels. The sensors measure heterogeneous time-varying …

We consider the problem of minimizing age of information in multihop wireless networks and
propose three classes of policies to solve the problem-stationary randomized, age …

The Age-of-Information (AoI) metric has been widely studied in the theoretical
communication networks and queuing systems literature. However, experimental evaluation …

We consider systems that require timely monitoring of sources over a communication
network, where the cost of delayed information is unknown, time-varying and possibly …

This paper focuses on the information freshness of finite-state Markov sources, using the
uncertainty of information (UoI) as the performance metric. Measured by Shannon's entropy …

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 consider a system with a single source that measures/tracks a time-varying quantity and
periodically attempts to report these measurements to a monitoring station. Each update …
