| Summary: | Peer-to-peer is emerging as a potentially disruptive
technology for content distribution in the mobile Internet. In
addition to the already well-known peer-to-peer file sharing, real-time
peer-to-peer streaming is gaining popularity. This paper
presents an effective real-time peer-to-peer streaming system for
the mobile environment. The basis for the system is a scalable
overlay network which groups peer into clusters according to
their proximity using RTT values between peers as a criteria for
the cluster selection. The actual media delivery in the system is
implemented using the partial RTP stream concept: the original
RTP sessions related to a media delivery are split into a number
of so-called partial streams according to a predefined set of
parameters in such a way that it allows low-complexity reassembly
of the original media session in real-time at the receiving
end. Partial streams also help in utilizing the upload capacity
with finer granularity than just per one original stream. This
is beneficial in mobile environments where bandwidth can be scarce. |
