In-Orbit Intelligence or Ground Offloading? Inference Freshness under Intermittent Satellite Connectivity
Ayse Nur Pehlivanoglu, Aimin Li, Elif Uysal
This paper studies how to balance onboard and ground computation under intermittent LEO connectivity for optimized inference freshness. As connectivity varies in time, the system s…
Age of Information in Time-Varying Multi-Priority Queues
Burak Karasakal, Aimin Li, Elif Uysal
In networks with intermittent connectivity, such as mobile, aerial, and space systems, maintaining information freshness is complicated by time-varying arrivals, service disruption…
ASTRA: Asynchronous Age-Aware Satellite Random Access via Mean-Field Control
Sayam Chakraborty, Aimin Li, Yigit Ince +2
Satellite Internet-of-Things (IoT) enables massive status-update services beyond terrestrial coverage, but grant-free uplink access creates a coupled freshness-control problem: inc…
Goal-Oriented Status Updating for Real-time Remote Inference over Networks with Two-Way Delay
Cagri Ari, Md Kamran Chowdhury Shisher, Yin Sun +1
We study a setting where an intelligent model (e.g., a pre-trained neural network) infers the real-time value of a target signal using data samples transmitted from a remote source…
Goal-Oriented Random Access (GORA)
Ahsen Topbas, Cagri Ari, Onur Kaya +1
We propose Goal-Oriented Random Access (GORA), where transmitters jointly optimize what to send and when to access the shared channel to a common access point, considering the ulti…
