Age of Information with On-Off Service
Ashirwad Sinha, Praful D. Mankar, Nikolaos Pappas +1
This paper considers a communication system where a source sends time-sensitive information to its destination. We assume that both arrival and service processes of the messages ar…
On the Interplay Between Deadline-Constrained Traffic and the Number of Allowed Retransmissions in Random Access Networks
Nikolaos Nomikos, Themistoklis Charalambous, Yvonne-Anne Pignolet +1
In this paper, a network comprising wireless devices equipped with buffers transmitting deadline-constrained data packets over a slotted-ALOHA random-access channel is studied. Alt…
Semantics-Aware Source Coding in Status Update Systems
Pouya Agheli, Nikolaos Pappas, Marios Kountouris
We consider a communication system in which the destination receives status updates from an information source that observes a physical process. The transmitter performs semantics-…
Semantics-Aware Active Fault Detection in Status Updating Systems
George Stamatakis, Nikolaos Pappas, Alexandros Fragkiadakis +1
With its growing number of deployed devices and applications, the Internet of Things (IoT) raises significant challenges for network maintenance procedures. In this work we address…
On-Demand AoI Minimization in Resource-Constrained Cache-Enabled IoT Networks with Energy Harvesting Sensors
Mohammad Hatami, Markus Leinonen, Zheng Chen +2
We consider a resource-constrained IoT network, where multiple users make on-demand requests to a cache-enabled edge node to send status updates about various random processes, eac…
Performance Analysis of a MIMO System with Bursty Traffic in the presence of Energy Harvesting Jammer
Sujatha Allipuram, Parthajit Mohapatra, Nikolaos Pappas +2
This paper explores the role of multiple antennas in mitigating jamming attacks for the Rayleigh fading environment with exogenous random traffic arrival. The jammer is assumed to…
