V. CONCLUSIONS
We have presented a streaming system based on network
coding for multimedia transmission in overlay mesh networks.
In our scheme, only a few nodes perform RNC in order to
meet a tradeoff between computational complexity, delay and
packet duplicates. Two different algorithms are proposed for
an effective placement of the NC nodes. The first algorithm
assumes full network knowledge, while only local statistics are
available for the second one. The experimental evaluation on
irregular networks shows that both schemes could achieve the
same throughput as a full network coding system with only a
few well-positioned NC nodes.
