ANALYSIS OF HETEROGENEOUS PEER TO PEER VIDEO STREAMING

Abstract

This thesis deals with the survey of peer to peer video streaming protocols and simulation of peer-to-peer video streaming architecture for heterogeneous node. The nodes are having different bandwidths and node may join and leave the system dynamically. The nodes of the ALM tree are deployed over the Internet widely and heterogeneously. So the extra transfer delay of packet will be added due to the bandwidth bottleneck between the heterogeneous nodes. Each node is having different packet loss, startup delay and playback jitters caused by the network congestion between the heterogeneous peers. In this thesis, a framework SmartPeerCast combination of the ALM tree and mesh framework of the P2P overlay is described. It maintains simplicity of ALM architecture and also utilizes all peers uploading bandwidth like the mesh framework to improve the startup time delay and playback jitters performance of the RTVB application .The nodes are added to overlay network based multicast tree at application level. It utilizes the leaf nodes bandwidth of high quality tree to forward the lower quality streaming to the nodes of the lower quality stream ALM trees. It uses QOS messages to change forwarding bandwidths and minimizing the packet jitters.
