Age of Information in a Single-Source Generate-at-Will Dual-Server Status Update System
Nail Akar, Sennur Ulukus
We study age of information (AoI) in a single-source dual-server status update system for the generate at will (GAW) scenario, consisting of an information source, dual servers, an…
AoII-Optimum Sampling of CTMC Information Sources Under Sampling Rate Constraints
Ismail Cosandal, Nail Akar, Sennur Ulukus
We consider a sensor that samples an -state continuous-time Markov chain (CTMC)-based information source process, and transmits the observed state of the source, to a remote mon…
Minimizing the Age of Two Heterogeneous Sources With Packet Drops Via Cyclic Schedulers
Sahan Liyanaarachchi, Sennur Ulukus, Nail Akar
In a communication setting where multiple sources share a single channel to provide status updates to a remote monitor, source transmissions need to be scheduled appropriately to m…
Modeling AoII in Push- and Pull-Based Sampling of Continuous Time Markov Chains
Ismail Cosandal, Nail Akar, Sennur Ulukus
Age of incorrect information (AoII) has recently been proposed as an alternative to existing information freshness metrics for real-time sampling and estimation problems involving…
Scalable Cyclic Schedulers for Age of Information Optimization in Large-Scale Status Update Systems
Nail Akar, Sahan Liyanaarachchi, Sennur Ulukus
We study cyclic scheduling for generate-at-will (GAW) multi-source status update systems with heterogeneous service times and packet drop probabilities, with the aim of minimizing…
