Age of Information with Age-Dependent Server Selection
Nail Akar, Ismail Cosandal, Sennur Ulukus
In this paper, we consider a single-source multi-server generate-at-will discrete-time non-preemptive status update system where update packets are transmitted using {\em only one}…
Semi-Markov Decision Process Framework for Age of Incorrect Information Minimization
Ismail Cosandal, Sennur Ulukus, Nail Akar
For a remote estimation system, we study age of incorrect information (AoII), which is a recently proposed semantic-aware freshness metric. In particular, we assume an information…
Optimal Source Coding of Markov Chains for Real-Time Remote Estimation
Ismail Cosandal, Sennur Ulukus
We revisit the source coding problem for a Markov chain under the assumption that the transmission times and how fast the Markov chain transitions its state happen at the same time…
Timely Tracking of a Wiener Process With Single Bit Quantization
Ismail Cosandal, Sahan Liyanaarachchi, Sennur Ulukus
We consider the problem of timely tracking of a Wiener process via an energy-conserving sensor by utilizing a single bit quantization strategy under periodic sampling. Contrary to…
Minimizing Functions of Age of Incorrect Information for Remote Estimation
Ismail Cosandal, Sennur Ulukus, Nail Akar
The age of incorrect information (AoII) process which keeps track of the time since the source and monitor processes are in sync, has been extensively used in remote estimation pro…
Source Coding for a Wiener Process
Sahan Liyanaarachchi, Ismail Cosandal, Sennur Ulukus
We develop a novel source coding strategy for sampling and monitoring of a Wiener process. For the encoding process, we employ a four level ``quantization'' scheme, which employs m…
Which Sensor to Observe? Timely Tracking of a Joint Markov Source with Model Predictive Control
Ismail Cosandal, Sennur Ulukus, Nail Akar
In this paper, we investigate the problem of remote estimation of a discrete-time joint Markov process using multiple sensors. Each sensor observes a different component of the joi…
