Abstract
This work considers the problem of peer-to-peer video streaming for a critical private web cast, for a medium sized heterogeneous network. The nodes can form an overlay network based on multicast tree at application level. The nodes are assumed to have different bandwidths and reliabilities, with a majority of the nodes having low bandwidths and low reliability such that they can only receive stream. A simulation model has been implemented to compare the single streaming scheme and Error Resilience schemes with Dual Disjoint Multicast Trees: Stream Replication and Multiple Description Coding (MDC). Simulation results indicate that MDC Error Resilience scheme provides lower average outage, better video quality and network utilization as packet loss and node failure probability increases. The Error Resilience schemes require multiple path diversified, disjoint trees. We discuss the significance of considering heterogeneous bandwidth and node reliability factor for maintaining multiple disjoint trees for Error Resilience. A disjoint tree algorithm Multi Level Dual Disjoint Trees (MLDDT) has been proposed, that further improves the results of MDC Error Resilience
