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…
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…
Ultra-Reliable Short-Packet Communications: Half-Duplex or Full-Duplex Relaying?
Yifan Gu, He Chen, Yonghui Li +1
This letter analyzes and compares the performance of full-duplex relaying (FDR) and half-duplex relaying (HDR) for ultra-reliable short-packet communications. Specifically, we deri…
Accumulate then Forward: An Opportunistic Relaying Protocol for Wireless-Powered Cooperative Communications
Ziyi Li, He Chen, Yifan Gu +2
This paper investigates a wireless-powered cooperative communication network consisting of a source, a destination and a multi-antenna decode-and-forward relay. We consider the rel…
