Abstract
Nowadays, peer-to-peer technology has provided users with cheap and powerful communicating facilities. However, P2P streaming system faces two challenges. Firstly, how to improve the poor Quality-of-Experience (QoE) in unpopular channel? Secondly, how to select peers to contribute their resources for assisting the unpopular channel in order to balance channel resources? This paper presents a cross-channel federation model to address these problems. The key idea is to identify a set of stable nodes in popular channel to assist the unpopular channel. These stable nodes, together with nodes in unpopular channel, are organized as mesh-based network, which facilitates the unpopular channel to enlarge the channel group and promote peer stability. This cross-channel federation model is evaluated through simulations. The results demonstrate its efficiency.
