Wireless mesh networks (WMNs) are expected to play an important role in the next-generation Internet because of its several advantages, such as self-organization, high capacity, low deployment cost and low maintenance cost. In this paper, we discuss how to provide robust home-to-home on-demand streaming on the basis of WMNs. A key challenge for such a community-based P2P multimedia system is how to efficiently place and replicate video clips across different home devices in the face of frequent online/offline behavior of users. In this paper, we propose an efficient data replication scheme called H2-VIP for home-to-home video streaming. H2-VIP computes the optimal number of replicas of video blocks. Our simulation results show that the proposed scheme can largely reduce the failure rate of home-to-home streaming at the cost of a small amount of extra storage space.
