Opportunistic coding based on source directed relay
基于源定向中继的机会网络编码的研究与实现

In this paper, the authors combined the idea of source directed relay and opportunistic coding, defined the butterfly and chain structure, proposed a new annulus structure of network coding further, and thus made the network coding much more easier to realize in wireless environment. The simulation results on platform of NS2 show that opportunistic coding can make the throughput and the energy efficiency higher obviously.
