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…
Optimizing Age of Information in Wireless Networks with Perfect Channel State Information
Rajat Talak, Sertac Karaman, Eytan Modiano
Age of information (AoI), defined as the time elapsed since the last received update was generated, is a newly proposed metric to measure the timeliness of information updates in a…
Distributed Scheduling Algorithms for Optimizing Information Freshness in Wireless Networks
Rajat Talak, Sertac Karaman, Eytan Modiano
Age of Information (AoI), measures the time elapsed since the last received information packet was generated at the source. We consider the problem of AoI minimization for single-h…
Optimizing Information Freshness in Wireless Networks under General Interference Constraints
Rajat Talak, Sertac Karaman, Eytan Modiano
Age of information (AoI) is a recently proposed metric for measuring information freshness. AoI measures the time that elapsed since the last received update was generated. We cons…
Capacity and Delay Scaling for Broadcast Transmission in Highly Mobile Wireless Networks
Rajat Talak, Sertac Karaman, Eytan Modiano
We study broadcast capacity and minimum delay scaling laws for highly mobile wireless networks, in which each node has to disseminate or broadcast packets to all other nodes in the…
