Dynamic Power Control for Packets with Deadlines
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
Wireless devices need to adapt their transmission power according to the fluctuating wireless channel in order to meet constraints of delay sensitive applications. In this paper, w…
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…
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…
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…
Minimum-Length Scheduling with Finite Queues: Solution Characterization and Algorithmic Framework
Vangelis Angelakis, Anthony Ephremides, Qing He +1
We consider a set of transmitter-receiver pairs, or links, that share a common channel and address the problem of emptying backlogged queues at the transmitters in minimum time. Th…
On Optimal Link Activation with Interference Cancellation in Wireless Networking
Di Yuan, Vangelis Angelakis, Lei Chen +2
A fundamental aspect in performance engineering of wireless networks is optimizing the set of links that can be concurrently activated to meet given signal-to-interference-and-nois…
