Efficient and Load-Balance Overlay Multicast Scheme with Path Diversity for Video Streaming
نویسندگان
چکیده
An overlay multicast is proposed to solve the scalability and deployment problems in IP Multicast. We propose a scheme, Topology-aware Load-balance Hierarchical Independent Tree (TLHIT), with topology-aware, load-balance and path diversity properties to improve the performance of overlay multicast. Compared to traditional methods, the proposed TLHIT constructs not only node-disjoint but also path-disjoint multicast trees where each node serves as an interior node in only one tree and different trees do not contain the same path. Moreover, TLHIT ensures load-balance property by building the multicast trees based on n-ary full tree. It ensures that each node serves almost the same amount of child nodes. Simulation results show that the reliability, efficiency, and load-balance properties of the proposed TLHIT are assured.

Path Diversity for Overlay Multicast Streaming
In this paper, we propose a new path-diversity based scheme for application layer multicast streaming over the Internet. Rather than building simple trees as in traditional multicast, we construct multicast k-DAGs, characterized by the property that each receiver has k parents. This multiplicity of parents, not only allows for streaming from multiple sources at the same time, thereby decorrelat...

In this thesis we investigate the problem of finding minimum delay applicationlayer multicast trees, such as the trees constructed in overlay networks. It is widely accepted that shortest path trees are not a good solution for this problem since such trees can have nodes with very large degree, termed high load nodes. The load on these nodes makes them a bottleneck in the distribution tree, due...
متن کاملA Cross-Layer Design for Wireless Ad-Hoc Peer-to-Peer Live Multimedia Streaming
Establishing peer-to-peer (P2P) live streaming for mobile ad hoc network (MANET) requires an efficient scheme to deliver the realtime data in the infrastructure-less disaster environment. However, P2P membership management is difficult in the dynamic mobility and resource limited MANET. In this paper, we present a cross-layer design for P2PMANET which integrates P2P DHT-based routing protocol a...
متن کاملError Resilient Video Streaming for Heterogeneous Networks
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 s...
متن کاملA cross-layer approach for real-time multimedia streaming on wireless peer-to-peer ad hoc network
Peer-to-peer (P2P) live streaming over mobile ad hoc network (MANET) is a state-of-theart technique for wireless multimedia applications, such as entertainments and disaster recovery. The peers share the live streaming over MANET via multi-hop wireless link, so an efficient data delivery scheme must be required. However, the high churn rate and the frequent mobility baffle the P2P membership ma...
