Blind Optimal User Association in Small-Cell Networks
Livia Elena Chatzieleftheriou, Apostolos Destounis, Georgios Paschos +1
We learn optimal user association policies for traffic from different locations to Access Points(APs), in the presence of unknown dynamic traffic demand. We aim at minimizing a bro…
Multi-Agent Deep Stochastic Policy Gradient for Event Based Dynamic Spectrum Access
Rahif Kassab, Apostolos Destounis, Dimitrios Tsilimantos +1
We consider the dynamic spectrum access (DSA) problem where Internet of Things (IoT) devices compete for time slots constituting a frame. Devices collectively monitor e…
Online Convex Optimization for Caching Networks
Georgios Paschos, Apostolos Destounis, George Iosifidis
We study the problem of wireless edge caching when file popularity is unknown and possibly non-stationary. A bank of caches receives file requests and a utility is accrued for…
Learning to Cooperate in D2D Caching Networks
Georgios S. Paschos, Apostolos Destounis, George Iosifidis
We consider a wireless device-to-device (D2D) cooperative network where memory-endowed nodes store and exchange content. Each node generates random file requests following an unkno…
Complexity of URLLC Scheduling and Efficient Approximation Schemes
Apostolos Destounis, Georgios S. Paschos
In this paper we address the problem of joint admission control and resource scheduling for \emph{Ultra Reliable Low Latency Communications} (URLLC). We examine two models: (i) the…
Learning to Cache With No Regrets
Georgios S. Paschos, Apostolos Destounis, Luigi Vigneri +1
This paper introduces a novel caching analysis that, contrary to prior work, makes no modeling assumptions for the file request sequence. We cast the caching problem in the framewo…
