Scalable packet loss recovery for mobile P2P streaming

Abstract

In a real-time peer-to-peer streaming system peers in the overlay network may arrive and depart in a very dynamic fashion especially in mobile environment. This manifests itself by a sudden uncontrolled disappearance of a sender and, as a consequence, packets being lost at the receiving side. To ensure seamless media playback the data should not have interruptions. Therefore, if some data packets are missing those should be requested and retrieved from other peers before the playback point reaches the gap in the reception buffer. This paper presents a scalable two-stage packet loss recovery mechanism for a real-time peer-to-peer streaming system using RTCP and RTSP. © 2010 Springer-Verlag Berlin Heidelberg.
