Age of Information under Source-Aware Truncated ARQ in Multi-Source Wireless Status Updating
Tianci Zhang, Aobo Liu, Zhengchuan Chen +4
This paper studies information timeliness in multi-source wireless Internet of Things (IoT) status updating systems under a truncated Automatic Repeat reQuest (ARQ) protocol. We pr…
Timeliness of Status Update System: The Effect of Parallel Transmission Using Heterogeneous Updating Devices
Zhengchuan Chen, Kang Lang, Nikolaos Pappas +4
Timely status updating is the premise of emerging interaction-based applications in the Internet of Things (IoT). Using redundant devices to update the status of interest is a prom…
Violation Probabilities of AoI and PAoI and Optimal Arrival Rate Allocation for the IoT-based Multi-Source Status Update System
Tianci Zhang, Shutong Chen, Zhengchuan Chen +4
Lots of real-time applications over Internet of things (IoT)-based status update systems have imperative demands on information freshness, which is usually evaluated by age of info…
Reconfigurable Intelligent Surface-Aided Spectrum Sharing Coexisting with Multiple Primary Networks
Zhong Tian, Zhengchuan Chen, Min Wang +2
Considering the spectrum sharing system (SSS) coexisting with multiple primary networks, we have employed a well-designed reconfigurable intelligent surface (RIS) to control the ra…
