Minimizing Age of Incorrect Information in Pull-Based Remote Estimation of a Markov Source
Ismail Cosandal, Sennur Ulukus, Nail Akar
In this paper, we consider a discrete-time pull-based remote estimation system involving an information source and a remote monitor where the information source is a finite-state i…
Dynamic Attack Surfaces: A Queue of Branching Processes
Ismail Cosandal, Abdullah Y. Etcibasi, C. Emre Koksal +1
Modern attack surfaces are inherently dynamic. Vulnerabilities emerge over time and they remain exposed to exploit until defenders discover and patch them. Artificial intelligence…
Dual-Regime Absorbing Markov Chain Theory in Remote Estimation: Age-Minimizing Push Policies
Ismail Cosandal, Sennur Ulukus, Nail Akar
For a remote estimation system, we study the optimization of age of incorrect information (AoII), which is a recently proposed semantic-aware information freshness metric. In parti…
When and Which Sensor to Observe? Timely Tracking of a Joint Markov Source
Ismail Cosandal, Sennur Ulukus, Nail Akar
We investigate the problem of remote estimation (at a monitor) of a discrete-time joint Markov process with individual components which can be observed with dedicated sensors. At a…
How Far Back in Time a Digital Twin Reflects the State of the Physical Object: Age of Staleness
Ismail Cosandal, Sennur Ulukus
The groundbreaking metric age of information (AoI) has been introduced to measure information freshness in communication networks. As transformational as it is, AoI metric falls sh…
