Age-Delay Tradeoffs in Queueing Systems
Rajat Talak, Eytan Modiano
We consider an M server system in which each server can service at most one update packet at a time. The system designer controls (1) scheduling - the order in which the packets ge…
A Theory of Uncertainty Variables for State Estimation and Inference
Rajat Talak, Sertac Karaman, Eytan Modiano
We develop a new framework of uncertainty variables to model uncertainty. An uncertainty variable is characterized by an uncertainty set, in which its realization is bound to lie,…
Age of Information for Discrete Time Queues
Vishrant Tripathi, Rajat Talak, Eytan Modiano
Age of information (AoI) is a time-evolving measure of information freshness, that tracks the time since the last received fresh update was generated. Analyzing peak and average Ao…
Age-Delay Tradeoffs in Single Server Systems
Rajat Talak, Eytan Modiano
Information freshness and low latency communication is important to many emerging applications. While Age of Information (AoI) serves as a metric of information freshness, packet d…
Age Optimal Information Gathering and Dissemination on Graphs
Vishrant Tripathi, Rajat Talak, Eytan Modiano
We consider the problem of timely exchange of updates between a central station and a set of ground terminals , via a mobile agent that traverses across the ground terminals alo…
