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…
Optimizing Adaptive Video Streaming in Mobile Networks via Online Learning
Theodoros Karagkioules, Georgios S. Paschos, Nikolaos Liakopoulos +3
In this paper, we propose a novel algorithm for video rate adaptation in HTTP Adaptive Streaming (HAS), based on online learning. The proposed algorithm, named Learn2Adapt (L2A), i…
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…
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…
