Age Optimal Sampling and Routing under Intermittent Links and Energy Constraints
Adem Utku Atasayar, Aimin Li, ÃaÄrı Arı +1
Links in practical systems, such as satellite--terrestrial integrated networks, exhibit distinct delay distributions, intermittent availability, and heterogeneous energy costs. The…
Taming the Heavy Tail: Age-Optimal Preemption
Aimin Li, YiÄit Ä°nce, Elif Uysal
This paper studies a continuous-time joint sampling-and-preemption problem, incorporating sampling and preemption penalties under general service-time distributions. We formulate t…
Optimal Sampling and Scheduling for Remote Fusion Estimation of Correlated Wiener Processes
Aimin Li, Elif Uysal
In distributed sensor networks, sensors often observe a dynamic process within overlapping regions. Due to random delays, these correlated observations arrive at the fusion center…
Optimal Sampling under Cost for Remote Estimation of the Wiener Process over a Channel with Delay
Süleyman Ãıtır, Orhan T. YavaÅcan, Elif Uysal
We address the optimal sampling of a Wiener process under sampling and transmission costs, with the samples being forwarded to a remote estimator over a channel with IID delay. The…
