PatchPeer: A scalable video-on-demand streaming system in hybrid wireless mobile peer-to-peer networks

Abstract

Video-on-demand service in wireless networks is one important step to achieving the goal of providing video services anywhere anytime. Typically, carrier mobile networks are used to deliver videos wirelessly. Since every video stream comes from the base station, regardless of what bandwidth sharing techniques are being utilized, the media stream system is still limited by the network capacity of the base station. The key to overcome the scalability issue is to exploit resources available at mobile clients in a peer-to-peer setting. We observe that it is common to have a carrier mobile network and a mobile peer-topeer network co-exist in a wireless environment. A feature of such hybrid environment is that the former offers high availability assurance, while the latter presents an opportunistic use of resources available at mobile clients. Our proposed video-on-demand technique, PatchPeer, leverages this network characteristic to allow the video-on-demand system scale beyond the bandwidth capacity of the server. Mobile clients

A system for peer-to-peer video streaming in resource constrained mobile environments

“…The authors propose changes to the existing WLAN specifications and to allow a mix mode unicast streaming and peer-to-peer video exchange. Another related work is PatchPeer [3] that is designed to "allow the video-on-demand system scale beyond the bitrate capacity of the server" by combining multicast with peer-to-peer technology (similar to MOVi). Related to our work is the Drive-Thru Internet approach of Ott and Kutscher [8] where mobile clients use a session protocol to maintain connectivity even in the presence of disrupted Internet connectivity.…”

“…The related work focuses on specific link-layer technologies [15], or requires a special mobility agent [14] [10], and considers mobility patterns of pedestrians [15] [3]. Our approach considers peers moving at the speeds of 200 km/h, e.g., high-speed trains, with more restriced and challenged GPRS and UMTS links.…”

Collaborative streaming system design as an underlay to cellular networks

“…Mobile users may form a P 2P netw ork based on secondary wireless interfaces such as 802.11 and repair packet losses. In P atch P eer [35], th e base statio n , w ith mul ticast capability, delivers video on dem and (VoD) to a set of mobile users. Any user w ith missing p arts downloads th e rem aining p a rts from th e neighboring user employing a unicast m ethod.…”
