Multimedia Streaming in Home Networks

Abstract
Home networks are increasingly being used for many challenging applications such as
audio/video streaming and interactive gaming. These applications usually involve
multicasting the stream from a media server to multiple consoles over a heterogeneous
mix of wireless and wired links (e.g., Ethernet, HomePlug AV, IEEE 802.11). Since
home networks do not have the advantage of large-scale traffic aggregation, there is
usually considerable fluctuations in the amount of bandwidth available in the network for
these applications. In this talk, I will describe some of our recent work that exploits
techniques such as rate adaptation, layered coding, and network coding to combat the
challenges of home networks.
