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…
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…
A Random Access G-Network: Stability, Stable Throughput, and Queueing Analysis
Ioannis Dimitriou, Nikolaos Pappas
The effect of signals on stability, throughput region, and delay in a two-user slotted ALOHA based random-access system with collisions is considered. This work gives rise to the d…
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…
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…
