| 摘 要： | 针对无线链路的不可靠性和物理层的广播特性，将网络编码与无线网络相结合，提出一种基于流的无线网络编码算法——FNC。该算法在先验参考路径的基础上，充分利用每个节点处的路由表项，探测编码机会，在有编码机会的节点对满足编码条件的数据流进行网络编码，达到提高网络吞吐量的目的。仿真结果表明：FNC有效提高了整个网络的吞吐量，改善了网络性能。

| Abstract: | In this paper, a flow based network coding algorithm in wireless networks is proposed, which combines network coding and wireless networks, and utilizes wireless lossy links and the broadcast nature of wireless media. Based on proactive routing, this algorithm exploits the routing table of every node, detects the coding opportunities, and encodes those packets from different flows satisfiable to the coding conditions, thus to increase the throughput of the networks. Simulation in NS-2 indicate that FNC has increased the throughput and improved the performance of the entire network. |
