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…
Absorbing Markov Chain-Based Analysis of Age of Information in Discrete-Time Dual-Queue Systems
Yifan Feng, Nail Akar, Zhengchuan Chen +1
Status update systems require the timely collection of sensing information for which deploying multiple sensors/servers to obtain diversity gains is considered as a promising solut…
Analysis of Age of Information for A Discrete-Time hybrid Dual-Queue System
Zhengchuan Chen, Yi Qu, Nikolaos Pappas +3
Using multiple sensors to update the status process of interest is promising in improving the information freshness. The unordered arrival of status updates at the monitor end pose…
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…
