Peer-To-Peer (P2P) streaming is attracting much attention. It requires neighbor selection to construct an overlay and delivers streaming data on it. Therefore, neighbor selection determines the performance of P2P streaming system. There is obvious heterogeneity of bandwidth and latency in current Internet. However, there is still a lack of neighbor selection approach suited for heterogeneous P2P streaming. Most current neighbor selection methods do not consider the heterogeneity or do not consider bandwidth and latency simultaneously. In this paper, the authors propose a new QoS driven neighbor selection method derived from the Metropolis-Hastings algorithm.
