Link rate allocation is very important for supporting high video playback rate in Peer-to-Peer video streaming. Although many studies can be found on resource allocation in P2P streaming in wired networks, very few studies have studied the problem in wireless networks, especially in Wireless Mesh Networks(WMNs), which is still challenging. To maximize the users' satisfaction of P2P streaming in WMNs, this paper focuses on link rate allocation problem and proposes a fully distributed algorithm to efficiently utilize the upload and download bandwidth of wireless mesh nodes. We firstly design an efficient P2P streaming system based on the experimental results coming from real deployment of our wireless mesh testbed. Due to non-uniform geographic distribution of the mobile users in typical deployments of WMNs, we formulate the link rate allocation problem into a network utility maximization problem and use user density as an important weight parameter in the problem. The simulation experiments demonstrate the significant performance enhancement by using the proposed rate allocation algorithm in WMNs.
