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…
Online Convex Optimization with Perturbed Constraints
Víctor Valls, George Iosifidis, Douglas J. Leith +1
This paper addresses Online Convex Optimization (OCO) problems where the constraints have additive perturbations that (i) vary over time and (ii) are not known at the time to make…
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…
Maximum Lifetime Analytics in IoT Networks
Victor Valls, George Iosifidis, Theodoros Salonidis
This paper studies the problem of allocating bandwidth and computation resources to data analytics tasks in Internet of Things (IoT) networks. IoT nodes are powered by batteries, c…
Pricing for Collaboration Between Online Apps and Offline Venues
Haoran Yu, George Iosifidis, Biying Shou +1
An increasing number of mobile applications (abbrev. apps), like Pokemon Go and Snapchat, reward the users who physically visit some locations tagged as POIs (places-of-interest) b…
