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…
SCORP: Scene-Consistent Multi-agent Diffusion Planning with Stable Online Reinforcement Post-Training for Cooperative Driving
Haojie Bai, Aimin Li, Ruoyu Yao +5
Cooperative driving is a safety- and efficiency-critical task that requires the coordination of diverse, interaction-realistic multi-agent trajectories. Although existing diffusion…
Age Optimal Sampling and Routing under Intermittent Links and Energy Constraints
Adem Utku Atasayar, Aimin Li, Çağrı 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, Yiğit İnce, 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…
