Improving P2P video streaming in wireless mesh networks

P2P Video Streaming has become a reliable and efficient solution for distributing video on the Internet. Similarly to regular P2P file-sharing, all the participating nodes exchange information. Wireless Mesh Networks, in turn, can be seen as a cost-effective solution to extend Internet access networks. In this paper we propose improvements to P2P Video Streaming. These improvements can provide gains in scenarios where the service is deployed over Wireless Mesh Networks and the nodes are simultaneously peers and packet forwarders. By using cross-layer interactions between application and network layers, we show that the proposed improvements reduce substantially the amount of traffic in the network.
