Abstract

Data-driven Overlay Network (DONet) is especially suitable for live stream in P2P environment. However, it demands the cooperation of individual nodes to exchange their buffer maps. Since these nodes are selfish and have their own interests, they might cheat about their buffer maps to reduce the forwarding burden. We analyze the impact of this kind of cheating behavior on the streaming quality of DONet by experiment in this paper. The experimental results show that buffer map cheating has considerable negative impact on the streaming quality in DONet.
