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…
UAV Trajectory Optimization for Time Constrained Applications
Emmanouil Fountoulakis, Georgios S. Paschos, Nikolaos Pappas
Unmanned Aerial Vehicles (UAVs) are poised to revolutionize communications. Utilizing their flexibility and fast deployment, we can deliver content in congested areas or provide se…
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…
Cache Optimization Models and Algorithms
Georgios Paschos, George Iosifidis, Giuseppe Caire
Storage resources and caching techniques permeate almost every area of communication networks today. In the near future, caching is set to play an important role in storage-assiste…
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…
