A Perspective on Time towards Wireless 6G
Petar Popovski, Federico Chiariotti, Kaibin Huang +4
With the advent of 5G technology, the notion of latency got a prominent role in wireless connectivity, serving as a proxy term for addressing the requirements for real-time communi…
Control of Status Updates for Energy Harvesting Devices that Monitor Processes with Alarms
George Stamatakis, Nikolaos Pappas, Apostolos Traganitis
In this work, we derive optimal transmission policies in an energy harvesting status update system. The system monitors a stochastic process which can be either in a normal or in a…
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…
An End-to-End Performance Analysis for Service Chaining in a Virtualized Network
Emmanouil Fountoulakis, Qi Liao, Nikolaos Pappas
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…
Delay Violation Probability and Age of Information Interplay in the Two-user Multiple Access Channel
Nikolaos Pappas, Marios Kountouris
In this paper, we study the interplay between delay violation probability and average Age of Information (AoI) in a two-user wireless multiple access channel with multipacket recep…
Age of Information in a Multiple Access Channel with Heterogeneous Traffic and an Energy Harvesting Node
Zheng Chen, Nikolaos Pappas, Emil Björnson +1
Age of Information (AoI) is a newly appeared concept and metric to characterize the freshness of data. In this work, we study the delay and AoI in a multiple access channel (MAC) w…
