Optimizing Information Freshness via Multiuser Scheduling with Adaptive NOMA/OMA
Qian Wang, He Chen, Changhong Zhao +3
This paper considers a wireless network with a base station (BS) conducting timely status updates to multiple clients via adaptive non-orthogonal multiple access (NOMA)/orthogonal…
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…
Optimizing Information Freshness in Two-Way Relay Networks
Bohai Li, He Chen, Nikolaos Pappas +1
In this paper, we investigate an amplify-and-forward (AF) based two-way cooperative status update system, where two sources aim to exchange status updates with each other as timely…
Design and Implementation of Time-Sensitive Wireless IoT Networks on Software-Defined Radio
Jiaxin Liang, He Chen, Soung Chang Liew
Time-sensitive wireless networks are an important enabling building block for many emerging industrial Internet of Things (IoT) applications. Quick prototyping and evaluation of ti…
Age-of-Information-based Scheduling in Multiuser Uplinks with Stochastic Arrivals: A POMDP Approach
Aoyu Gong, Tong Zhang, He Chen +1
In this paper, we consider a multiuser uplink status update system, where a monitor aims to timely collect randomly generated status updates from multiple end nodes through a share…
Physical Layer Authentication for Non-Coherent Massive SIMO-Enabled Industrial IoT Communications
Zhifang Gu, He Chen, Pingping Xu +2
Achieving ultra-reliable, low-latency and secure communications is essential for realizing the industrial Internet of Things (IIoT). Non-coherent massive multiple-input multiple-ou…
