摘要： 提出一种新的基于网络编码的无线传感器网络定向扩散路由协议。在定向扩散路由建立的过程中利用随机线性网络编码，使中继节点对收到的分组进行网络编码后再转发，以减少网络中分组传输的次数，优化网络带宽利用率。基于网络仿真平台NS2的仿真结果表明，新协议的网络性能得到有效改善，节点的平均剩余能量和网络吞吐量有显著提高。

Abstract: A novel Directed Diffusion(DD) routing protocol for Wireless Sensor Network(WSN) based on network coding is presented. Randomized linear network coding is used in the processes of establishing Directed Diffusion(DD) routing. The intermediate nodes performs coding on received packets, then forwards them. The number of packets transmission is reduced. The use of bandwidth is more efficient. Simulation results based on NS2 show that compared with the original DD routing protocol, the average remain energy of nodes and network throughput are both increased efficiently.
