Cacheable and Non-Cacheable Traffic Interplay in a Relay-Assisted Wireless Network
Ioannis Avgouleas, Nikolaos Pappas, Vangelis Angelakis
We study a discrete-time wireless network that serves both cacheable and non-cacheable traffic with assistance of a relay node with storage capabilities for both types of traffic.…
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…
Wireless Caching Helper System with Heterogeneous Traffic and Random Availability
Ioannis Avgouleas, Nikolaos Pappas, Vangelis Angelakis
Multimedia content streaming from Internet-based sources emerges as one of the most high demanded services by wireless users. In order to alleviate excessive traffic due to multime…
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…
