Adaptive Design of mmWave Initial Access Codebooks using Reinforcement Learning
Sabrine Aroua, Christos Anastasios Bovolis, Bo Göransson +3
Initial access (IA) is the process by which user equipment (UE) establishes its first connection with a base station. In 5G systems, particularly at millimeter-wave frequencies, IA…
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…
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…
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…
Learn2MAC: Online Learning Multiple Access for URLLC Applications
Apostolos Destounis, Dimitrios Tsilimantos, Mérouane Debbah +1
This paper addresses a fundamental limitation of previous random access protocols, their lack of latency performance guarantees. We consider IoT transmitters competing for upli…
Selective Fair Scheduling over Fading Channels
Apostolos Destounis, Georgios S. Paschos, David Gesbert
Imposing fairness in resource allocation incurs a loss of system throughput, known as the Price of Fairness (). In wireless scheduling, increases when serving users with…
Streaming Big Data meets Backpressure in Distributed Network Computation
Apostolos Destounis, Georgios S. Paschos, Iordanis Koutsopoulos
We study network response to queries that require computation of remotely located data and seek to characterize the performance limits in terms of maximum sustainable query rate th…
