Age of Information-Oriented Probabilistic Link Scheduling for Device-to-Device Networks
Lixin Wang, Qian Wang, He Chen +1
This paper focuses on optimizing the long-term average age of information (AoI) in device-to-device (D2D) networks through age-aware link scheduling. The problem is naturally formu…
Fresh-Fi: Enhancing Information Freshness in Commodity WiFi Systems via Customizing Lower Layers
Zixiao Han, Qian Wang, He Chen
Enhancing information freshness in wireless networks has gained significant attention in recent years. To optimize or analyze information freshness, which is often characterized by…
Age of Information in Reservation Multi-Access Networks with Stochastic Arrivals
Qian Wang, He Chen
This paper investigates the Age of Information (AoI) performance of Frame Slotted ALOHA with Reservation and Data slots (FSA-RD). We consider a symmetric multi-access network where…
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…
Secure Status Updates under Eavesdropping: Age of Information-based Physical Layer Security Metrics
He Chen, Qian Wang, Parthajit Mohapatra +1
This letter studies the problem of maintaining information freshness under passive eavesdropping attacks. The classical three-node wiretap channel model is considered, in which a s…
