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…
