Bandwidth-Aware Scheduling in Media Streaming Under Heterogeneous Bandwidth.

Data-driven media streaming has been deployed gradually over the Internet. In such systems, node periodically exchanges media block availability and fetches desirable blocks from neighbors. The issue on optimizing fetching blocks is called block scheduling and receives focus, especially in heterogeneous overlay. In this paper Bandwidth-Aware Scheduling (BAS) formulates such problem by incorporating bandwidth and block deadline, as well as node importance. Simulation results verify that BAS performs much better than existing ones. [ABSTRACT FROM AUTHOR]
