Secure Communications for the Two-user Broadcast Channel with Random Traffic
Parthajit Mohapatra, Nikolaos Pappas, Jemin Lee +2
In this work, we study the stability region of the two-user broadcast channel (BC) with bursty data arrivals and security constraints. We consider the scenario, where one of the re…
Wireless Network-Level Partial Relay Cooperation: A Stable Throughput Analysis
Nikolaos Pappas, Jeongho Jeon, Di Yuan +2
In this work, we study the benefit of partial relay cooperation. We consider a two-node system consisting of one source and one relay node transmitting information to a common dest…
Service Allocation in a Mobile Fog Infrastructure under Availability and QoS Constraints
Nader Daneshfar, Nikolaos Pappas, Valentin Polishchuk +1
The next generation of mobile networks, namely 5G, and the Internet of Things (IoT) have brought a large number of delay sensitive services. In this context Cloud services are migr…
Age and Value of Information: Non-linear Age Case
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a real-time status update system consisting of a source-destination network. A stochastic process is observed at the source, and samples, so called status updates, are…
Probabilistic Cooperation of a Full-Duplex Relay in Random Access Networks
Ioannis Avgouleas, Nikolaos Pappas, Di Yuan +1
In this work, we analyze the probabilistic cooperation of a full-duplex relay in a multiuser random-access network. The relay is equipped with on/off modes for the receiver and the…
Stable Throughput Region of the Two-User Broadcast Channel
Nikolaos Pappas, Marios Kountouris, Anthony Ephremides +1
In this paper we consider the two-user broadcast channel and we characterize its stable throughout region. We start the analysis by providing the stability region for the general c…
