Optimizing Age of Information in Wireless Uplink Networks with Partial Observations

Jingwei Liu, Rui Zhang, Aoyu Gong +1

We consider a wireless uplink network consisting of multiple end devices and an access point (AP). Each device monitors a physical process with stochastic arrival of status updates…
