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…
