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…
Absorbing Markov Chain-Based Analysis of Age of Information in Discrete-Time Dual-Queue Systems
Yifan Feng, Nail Akar, Zhengchuan Chen +1
Status update systems require the timely collection of sensing information for which deploying multiple sensors/servers to obtain diversity gains is considered as a promising solut…
Structured Estimators: A New Perspective on Information Freshness
Sahan Liyanaarachchi, Sennur Ulukus, Nail Akar
In recent literature, when modeling for information freshness in remote estimation settings, estimators have been mainly restricted to the class of martingale estimators, meaning t…
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…
How to Maximize Efficiency in Systems with Exhausted Workers
Elif Beray Sariisik, Melih Bastopcu, Nail Akar +1
We consider the problem of assigning tasks efficiently to a set of workers that can exhaust themselves as a result of processing tasks. If a worker is exhausted, it will take a lon…
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…
Fully Decentralized Computation Offloading in Priority-Driven Edge Computing Systems
Shubham Aggarwal, Melih Bastopcu, Muhammad Aneeq uz Zaman +3
We develop a novel framework for fully decentralized offloading policy design in multi-access edge computing (MEC) systems. The system comprises power-constrained user equipmen…
