Abstract
Abstract—We consider a community of multi-homed wireless de-vices, where each device has both a wireless wide area network (WWAN) interface to connect to the Internet and a wireless local area network (WLAN) interface to connect to its neighbors. Sup-pose users in the community are interested in receiving the same piece of delay-sensitive media content, and are willing to share their network resources. It is obvious that the community can ben-efit from the bundling of WWAN links and achieve higher aggre-gate bandwidth that is not possible with a single user with a single WWAN connection. What is not obvious is that by inverse multi-plexing or striping packets across multiple WWAN channels, one can also improve the goodput of delay-sensitive media traffic by striping FEC and ARQ packets across available channels. In this paper, we analyze the potential benefits of striping media traffic and develop algorithms that take advantage of these benefits to op-timize the delivery of delay-sensitive media streams to a wireless multi-homed device community. Results show dramatic improve-ment over naïve striping schemes such as weighted round robin both in terms of packet loss ratio, and in terms of peak signal-to-noise ratio for H.264 video streaming. Index Terms—Multimedia streaming, packet striping, wireless networks. I.
