ABSTRACT
The upload contribution of peers in a peer-to-peer streaming system depends on their willingness to contribute as well as their physical limitation. Several incentive schemes have been proposed to enforce non-willing peers to cooperate. But we find it of great interest to see how physically constrained, with respect to resources, peers can be supported by a streaming application. In this paper we investigate how free-riders, namely non-contributing peers, can be served in a peer-to-peer streaming system. We examine different prioritization schemes that are used by high contributing peers to prioritize other contributing peers over free-riders and show that as the level of prioritization increases, contributing peers receive higher quality but the average quality drops. To avoid this, we propose an incentive mechanism that encourages contributing peers to upload to free-riders so that the average quality experienced by the peers in the overlay is maximized.

A framework for architecting peer-to-peer receiver-driven overlays
NOSSDAV '04: Proceedings of the 14th international workshop on Network and operating systems support for digital audio and videoThis paper presents a simple and scalable framework for architecting peer-to-peer overlays called Peer-to-peer Receiver-driven Overlay (or PRO). PRO is designed for non-interactive streaming applications and its primary design goal is to maximize ...
Dynamic Bandwidth Auctions in Multioverlay P2P Streaming with Network Coding
In peer-to-peer (P2P) live streaming applications such as IPTV, it is natural to accommodate multiple coexisting streaming overlays, corresponding to channels of programming. In the case of multiple overlays, it is a challenging task to design an ...
P2P streaming: use of advertisements as incentives
MMSys '12: Proceedings of the 3rd Multimedia Systems ConferencePeer-to-Peer (P2P) streaming systems, such as PPLive, have become a popular service with the widespread deployment of broadband networks. However, P2P streaming systems still face free-riding problems, similar to those that have been observed in P2P ...
