Mobility-aware peer-to-peer live-streaming

Application Layer Multicast (ALM) has become a popular form of content distribution. It shows some favourable properties like inherent scalability and the overcoming of the traditional client-server bottleneck. In the future, a large fraction of the participants in ALM systems will be mobile (eg. smart-phones or netbooks) and demand for a proper inclusion and mobility handling. After analyzing current mobility protocols, we developed an integrated approach to handle mobility within push-based ALM live-streaming systems and show that an adequate mobility handling can preserve the operability of the system even in a worst-case scenario with high mobility and nodes with very heterogeneous bandwidths.
