Optimizing Information Freshness for Cooperative IoT Systems with Stochastic Arrivals
Bohai Li, Qian Wang, He Chen +2
This paper considers a cooperative Internet of Things (IoT) system with a source aiming to transmit randomly generated status updates to a designated destination as timely as possi…
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…
Multiuser Scheduling for Minimizing Age of Information in Uplink MIMO Systems
He Chen, Qian Wang, Zheng Dong +1
This paper studies the user scheduling problem in a multiuser multiple-input multi-output (MIMO) status update system, in which multiple single-antenna devices aim to send their la…
Minimizing Age of Information via Hybrid NOMA/OMA
Qian Wang, He Chen, Yonghui Li +1
This paper considers a wireless network with a base station (BS) conducting timely transmission to two clients in a slotted manner via hybrid non-orthogonal multiple access (NOMA)/…
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…
Minimizing Age of Information for Real-Time Monitoring in Resource-Constrained Industrial IoT Networks
Qian Wang, He Chen, Yonghui Li +2
This paper considers an Industrial Internet of Thing (IIoT) system with a source monitoring a dynamic process with randomly generated status updates. The status updates are sent to…
