Optimizing Information Freshness in Two-Hop Status Update Systems under a Resource Constraint
Yifan Gu, Qian Wang, He Chen +2
In this paper, we investigate the age minimization problem for a two-hop relay system, under a resource constraint on the average number of forwarding operations at the relay. We f…
Software-Defined Radio Implementation of Age-of-Information-Oriented Random Access
Zixiao Han, Jiaxin Liang, Yifan Gu +1
More and more emerging Internet of Things (IoT) applications involve status updates, where various IoT devices monitor certain physical processes and report their latest statuses t…
Age-of-Information Dependent Random Access for Massive IoT Networks
He Chen, Yifan Gu, Soung-Chang Liew
As the most well-known application of the Internet of Things (IoT), remote monitoring is now pervasive. In these monitoring applications, information usually has a higher value whe…
Minimizing the Age of Information of Cognitive Radio-Based IoT Systems Under A Collision Constraint
Qian Wang, He Chen, Yifan Gu +2
This paper considers a cognitive radio-based IoT monitoring system, consisting of an IoT device that aims to update its measurement to a destination using cognitive radio technique…
On the Age of Information of Short-Packet Communications with Packet Management
Rui Wang, Yifan Gu, He Chen +2
In this paper, we consider a point-to-point wireless communication system. The source monitors a physical process and generates status update packets according to a Poisson process…
Minimizing Age of Information in Cognitive Radio-based IoT Systems: Underlay or Overlay?
Yifan Gu, He Chen, Chao Zhai +2
We consider a cognitive radio-based Internet-of-Things (CR-IoT) network consisting of one primary IoT (PIoT) system and one secondary IoT (SIoT) system. The IoT devices of both the…
