摘　　要：流间网络编码具有改善无线网络性能的潜力,然而,由于实际网络中编码机会数量通常十分有限,仅仅被动地利用编码机会无法获得高的性能增益.编码感知路由的核心思想是使用有利于网络编码的路由,它通过在路由建立阶段构造特定的编码结构,可以主动创造编码机会.系统地总结了流间网络编码中的编码结构,并以此为主线,分类介绍了编码感知路由的研究现状.最后,对编码感知路由的研究热点进行了展望.The incorporation of inter-session network coding in wireless networks has the potential to remarkably improve the network performance. Unfortunately, the amount of existing coding opportunities in practical networks is limited, which hinders high performance gain by passively using coding opportunities. To overcome this issue, the network-coding-aware routing attempts to promote network coding by creating coding opportunities through constructing specific coding structures in the routing establishment phase. This paper systematically summarizes existing coding structures in inter-session network coding. From the perspective of coding structure, the state of the art of network-coding-aware routing is reported. At last, development trends of network-coding-aware routing are discussed.
