Age of Information in Reservation Multi-Access Networks with Stochastic Arrivals: Analysis and Optimization
Qian Wang, He Chen
This paper analyzes and optimizes the average Age of Information (AAoI) of Frame Slotted ALOHA with Reservation and Data slots (FSA-RD) in a multi-access network, where multiple us…
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 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…
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…
