The Age of Information in a Discrete Time Queue: Stationary Distribution and Non-linear Age Mean Analysis
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
In this work, we investigate information freshness in a status update communication system consisting of a source-destination link. Initially, we study the properties of a sample p…
The Cost of Delay in Status Updates and their Value: Non-linear Ageing
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a status update communication system consisting of a source-destination link. A stochastic process is observed at the source, where samples are extracted at random time…
Age of Information Performance of Multiaccess Strategies with Packet Management
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a system consisting of source nodes communicating with a common receiver. Each source node has a buffer of infinite capacity to store incoming bursty traffic in the…
Age of Information and Throughput in a Shared Access Network with Heterogeneous Traffic
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a cognitive shared access scheme consisting of a high priority primary node and a low priority network with secondary nodes accessing the spectrum. Assuming bursty…
Age and Value of Information: Non-linear Age Case
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a real-time status update system consisting of a source-destination network. A stochastic process is observed at the source, and samples, so called status updates, are…
