Mesh-based Overlay Enhancing Live Video Quality in Pull-based P2P Systems
In: 3rd IEEE International Conference on Communication Software and Networks (ICCSN 2011), edited by IEEE, Xi'an, China, pages 326 - 332.
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 over an overlay network. We propose a
mesh-based overlay construction mechanism that enhances the
received video quality while minimizing, as much as
possible, the play-out delay. The principal feature
provides each newcomer with a set of neighbors holding
almost the same video segments and enough available
transmission capacities to deal with its requests. A
particular algorithm has been designed to estimate the
peer's available capacities. The results of simulations
show our mechanism efficiency in heterogeneous systems.
