A promising feature brought along the progressive deployment of LTE concerns the increase of the uplink bandwidth. We exploit this new capability by focusing on an innovative usage defined by the simultaneous transmission of live video and contextual data caught through end user devices like smartphones towards websites or distant spectators.

— Nowadays, Peer-to-Peer (P2P) networks play an essential role in large scale live video transmission. Though many algorithms have been proposed to deal with packet loss in P2P networks, there is still a lack of mechanisms dealing with the delay and loss constraints of live video streaming. In this paper, we propose a new loss recovery mechanism allowing(More)
To deal with the explosion of mobile traffic, network operators deploy heterogeneous networks (HetNet), a combination of macro and pico eNodeBs. In this paper, we propose an optimization framework for the study of the optimal performances of HetNet on the uplink. We focus on video traffic because technologies like WebRTC allow mobile users to upload live(More)
Nowadays, Peer-to-Peer (P2P) live streaming applications have attracted great interest. Despite the fact that numerous systems have been proposed in the past, there are still problems concerning delay and quality requirements of live video distribution. In this paper, we consider a pull-based P2P live video streaming system where the video is disseminated(More)
— Les réseaux pair-à-pair (P2P) jouent aujourd'hui un rôle primordial dans la livraison de la vidéo à grande échelle. La perte des paquets sur les réseaux IP, peut affecter défavorablement la qualité de la vidéo reçue. Différents mécanismes de réparation de perte sont utilisés aujourd'hui. Ces mécanismes ont été proposés initialement pour des applications(More)
