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 particular, we assume an information source that observes a discrete-time finite-state Markov chain (DTMC…

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 given time slot, the monitor has the option of staying idle or sending a pull request to one of the…
