摘要Abstract: 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.
