Energy measurements for mobile cooperative video streaming

Jahed, Karim; Younes, Mounir; Sharafeddine, Sanaa (IEEE, 2018-06-28)

In a classical mobile video streaming architecture, the server is responsible for processing each request from the mobile clients even if those requests are for the same content in the same geographical area. This tends ...
Exploiting multiple wireless interfaces in smartphones for traffic offloading

Sharafeddine, Sanaa; Jahed, Karim; Abbas, Nadine; Yaacoub, Elias; Dawy, Zaher (IEEE, 2018-06-21)

Smartphones are evolving at a fast rate in terms of their computational, storage, and communications capabilities. A high-end smartphone is equipped with multiple wireless interfaces with varying bit rates, energy consumption ...
Failure recovery in wireless content distribution networks with device-to-device cooperation

Sharafeddine, Sanaa; Jahed, Karim; Farhat, Omar; Dawy, Zaher (2018-06-06)

Device-to-device cooperation has emerged as a prominent solution to a wide range of challenges in large-scale wireless networks. However, the ad hoc nature of cooperative networks and their proneness to failure are a major ...
An optimized approach to video traffic splitting in heterogeneous wireless networks with energy and QoE consideration

Abbas, Nadine; Hajj, Hazem; Dawy, Zaher; Jahed, Karim; Sharafeddine, Sanaa (2018-06-06)

Due to the exploding traffic demands with the ubiquitous anticipated spread of 5G and Internet of Things, research has been active to devise mechanisms for meeting these demands while maintaining high quality user experience. ...
Optimized device centric aggregation mechanisms for mobile devices with multiple wireless interfaces

Sharafeddine, Sanaa; Jahed, Karim; Fawaz, Marwan (2018-06-07)

Wireless broadband technologies and services are witnessing exponential growth to meet the demands of mobile users. State-of-the-art wireless networks are evolving with enhancements spanning all protocol layers and all ...
Practical device-centric WiFi/cellular link aggregation mechanism for mobile devices

Jahed, Karim; Fawaz, Marwan; Sharafeddine, Sanaa (IEEE, 2018-06-28)

One key enhancement in recent 3GPP cellular standard releases is WiFi/cellular network inter-operation and integration with protocols and techniques that can optimize target performance metrics. 3GPP specifications focus ...
Scalable Multimedia Streaming in Wireless Networks with Device-to-Device Cooperation

Jahed, Karim; Sharafeddine, Sanaa; Moussawi, Abdallah; Abou Daya, Abbas; Dbouk, Hassan; Kassir, Saadallah; Dawy, Zaher (Association for Computing Machinery, 2018-06-29)

We present a scalable mobile multimedia streaming system with device-to-device cooperation that enables common content distribution in dense wireless networking environments. This is particularly applicable to use cases ...
Social-Aware Device-to-Device Offloading Based on Experimental Mobility and Content Similarity Models

Aoude, LynnSharafeddine, Sanaa; Dawy, Zaher; Sharafeddine, Sanaa; Frenn, Karim; Jahed, Karim (2018-06-07)

Device-to-device (D2D) offloading has been shown to be a highly effective technique to enhance the performance of wireless networks. Yet, for any two mobile users to share data efficiently and reliably via D2D links, they ...
