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…
On the Role of Age of Information in the Internet of Things
Mohamed A. Abd-Elmagid, Nikolaos Pappas, Harpreet S. Dhillon
In this article, we provide an accessible introduction to the emerging idea of Age of Information (AoI) that quantifies freshness of information and explore its possible role in th…
Traversing Virtual Network Functions from the Edge to the Core: An End-to-End Performance Analysis
Emmanouil Fountoulakis, Qi Liao, Manuel Stein +1
Future mobile networks supporting Internet of Things are expected to provide both high throughput and low latency to user-specific services. One way to overcome this challenge is t…
Optimal Policies for Status Update Generation in a Wireless System with Heterogeneous Traffic
George Stamatakis, Nikolaos Pappas, Apostolos Traganitis
A large body of applications that involve monitoring, decision making, and forecasting require timely status updates for their efficient operation. Age of Information (AoI) is a ne…
On the Benefits of Network-Level Cooperation in Millimeter-Wave Communications
Cristian Tatino, Nikolaos Pappas, Ilaria Malanchini +2
Relaying techniques for millimeter-wave wireless networks represent a powerful solution for improving the transmission performance. In this work, we quantify the benefits in terms…
