Information Freshness for Timely Detection of Status Changes
Songtao Feng, Jing Yang
In this paper, we aim to establish the connection between Age of Information (AoI) in network theory, information uncertainty in information theory, and detection delay in time ser…
Adaptive Coding for Information Freshness in a Two-user Broadcast Erasure Channel
Songtao Feng, Jing Yang
In this paper, we investigate the impact of coding on the Age of Information (AoI) in a two-user broadcast symbol erasure channel with feedback. We assume each update consists of $…
Age-Optimal Transmission of Rateless Codes in an Erasure Channel
Songtao Feng, Jing Yang
In this paper, we examine a status updating system where updates generated by the source are sent to the monitor through an erasure channel. We assume each update consists of s…
When to Preempt? Age of Information Minimization under Link Capacity Constraint
Boyu Wang, Songtao Feng, Jing Yang
In this paper, we consider a scenario where a source continuously monitors an object and sends time-stamped status updates to a destination through a rate-limited link. We assume u…
To Skip or to Switch? Minimizing Age of Information under Link Capacity Constraint
Boyu Wang, Songtao Feng, Jing Yang
Consider a scenario where a source continuously monitors an object and sends time-stamped status updates to a destination through a rate-limited link. In order to measure the "fres…
