Learning a QoE Metric from Social Media and Gaming Footage

Defining a universal metric for Quality of Experience (QoE) is notoriously hard due to the complex relationship between low-level performance metrics and user satisfaction. The most common metric, the Mean Opinion Score (MOS), has well-known biases and inc ...

Toward Internet Performance Transparency

Georgia Fragkouli

From medical support to education and remote work, our everyday lives increasingly depend on Internet performance. When users experience poor performance, however, the decentralization of the Internet allows limited visibility into which network is respons ...

Adaptation and Learning Over Networks Under Subspace Constraints-Part I: Stability Analysis

Ali H. Sayed, Stefan Vlaski, Roula Nassif

This paper considers optimization problems over networks where agents have individual objectives to meet, or individual parameter vectors to estimate, subject to subspace constraints that require the objectives across the network to lie in low-dimensional ...

Enhancing model-based feedback perimeter control with data-driven online adaptive optimization

Nikolaos Geroliminis, Anastasios Kouvelas, Mohammadreza Saeedmanesh

Most feedback perimeter control approaches that are based on the Macroscopic Fundamental Diagram (MFD) and are tested in detailed network structures restrict inflow from the external boundary of the network. Although such a measure is beneficial for the ne ...

Software Framework for Integrated Modelling and Dimensioning of Backbone Optical Networks

Sébastien Rumley

Modelling, dimensioning and performance analysis of optical backbone networks is the main concern of this thesis. Modelling consists in representing a network under a abstract form, simpler and easier to analyse, the model. Dimensioning is achieved when ne ...

Network Coding: Beyond Throughput Benefits

Christina Fragouli

Network coding enables novel network functionalities and thus offers a wider canvas of choices when optimizing an information flow problem. In this paper, we examine the simplest possible information flow problem, a unicast connection, and explore what we ...

Performance Evaluation of Impulse Radio UWB Networks using Common or Private Acquisition Preambles

Jean-Yves Le Boudec, Ruben Merz

For impulse-radio ultra-wide band (IR-UWB) networks without global synchronization, the first step for correct packet reception is packet detection and timing acquisition: Before recovering the payload of the packet, the destination must detect that the pa ...
