A Persistence-Aware Framework for Age Violation Control in Wireless Status Update Systems
Haoyuan Pan, Chen Chen, Shiyong Zhou +2
Timely and reliable status updates are essential for emerging QoS-sensitive wireless applications. Common age of information (AoI)-based metrics, such as average AoI and age violat…
Diffusion Model-based Reinforcement Learning for Version Age of Information Scheduling: Average and Tail-Risk-Sensitive Control
Haoyuan Pan, Sizhao Chen, Zhaorui Wang +1
Ensuring timely and semantically accurate information delivery is critical in real-time wireless systems. While Age of Information (AoI) quantifies temporal freshness, Version Age…
Low-Power Random Access for Timely Status Update: Packet-based or Connection-based?
Tse-Tin Chan, Jian Feng, Haoyuan Pan
This paper studies low-power random access protocols for timely status update systems with information freshness requirements, measured by age of information (AoI). In an extensive…
Improving Information Freshness via Backbone-Assisted Cooperative Access Points
Haoyuan Pan, Yu Zhou, Tse-Tin Chan +3
Information freshness, characterized by age of information (AoI), is important for sensor applications involving timely status updates. In many cases, the wireless signals from one…
Semantic Communication-Empowered Physical-layer Network Coding
Shuai Yang, Haoyuan Pan, Tse-Tin Chan +1
In a two-way relay channel (TWRC), physical-layer network coding (PNC) doubles the system throughput by turning superimposed signals transmitted simultaneously by different end nod…
Timely Status Update: Should ARQ be Used in Two-Hop Networks?
Jian Feng, Haoyuan Pan, Tse-Tin Chan +1
This paper investigates the information freshness of two-hop networks. Age of information (AoI) is used as the metric to characterize the information freshness, defined as the time…
Is Multichannel Access Useful in Timely Information Update?
Jiaxin Liang, Haoyuan Pan, Soung Chang Liew
This paper investigates information freshness of multichannel access in information update systems. Age of information (AoI) is a fundamentally important metric to characterize inf…
