Inter-Overlay Cooperation in High-Bandwidth Overlay Multicast

Tags:
bandwidth issues

Overview The cooperation of end users can be exploited to boost the performance of high-bandwidth multicast. While intra-overlay cooperation, the mechanism for cooperation within a single overlay (multicast group), has been extensively studied, little attention has been paid to inter-overlay cooperation. This paper explores the possibility and effects of cooperation among co-existing heterogeneous overlays in the context of live media streaming, where bandwidth is the bottleneck resource. To motivate such a kind of cooperation, the paper designs a reputation-based incentive mechanism that differentiates user' streaming qualities based on the amount of data actually forwarded by individual users.
