SAMP: supporting multi-source heterogeneity in mobile P2P IPTV system

Peer-to-Peer (P2P) streaming provides an effective method to deploy large-scale internet protocol television (IPTV) application over today¿s Internet. A major challenge in designing such an application is how to deal with content delivery among heterogeneous clients. Especially, with the development of the mobile internet and smart phones, how to provide an effective multi-source heterogeneous P2P IPTV solution becomes of great importance. Due to the special requirement of supporting differentiated multiple video streaming for different users, already existing P2P live video streaming techniques are inappropriate to be adopted directly. Therefore, this paper proposes a source-aware mobile P2P IPTV solution (SAMP) to provide multi-source live streaming for heterogeneous clients. In detail, SAMP includes a source-aware P2P topology construction algorithm to deduce the bandwidth occupation and the control overhead among the P2P clients, and contains a source-aware P2P streaming scheduling algorithm to further enhance the delay performance of the P2P IPTV system. The evaluation results show that the proposed SAMP scheme can provide a differentiated multi-source live streaming for heterogeneous clients with reduced bandwidth consumption, control overhead, and delivery delay.
