Age Debt: A General Framework For Minimizing Age of Information
Vishrant Tripathi, Eytan Modiano
We consider the problem of minimizing age of information in general single-hop and multihop wireless networks. First, we formulate a way to convert AoI optimization problems into e…
Age of Information: An Introduction and Survey
Roy D. Yates, Yin Sun, D. Richard Brown +3
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-laten…
A Whittle Index Approach to Minimizing Functions of Age of Information
Vishrant Tripathi, Eytan Modiano
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 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…
