摘　　要：将源定向中继的思想与机会网络编码结合起来,定义了蝶形结构和链状结构的机会网络编码,并提出一种新的环形结构,大大地降低了网络编码的实现难度,从而使网络编码在无线环境下的应用成了现实。在NS2平台上的仿真结果表明,进行机会网络编码后,吞吐量明显提高,同时具有高能量效率。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.
