针对网络编码算法的能量开销大、解码出错率高等问题，提出一种多重信道感知的主动机制网络编码算法，该算法建立了系统模型来分析网络编码的工作方式，以最小化样本作为代价，采用多重信道感知的方法来检验中继节点的编码效果，使网络从中继节点的编码效果中进行学习，从而将源信息发送给编码效果较好的中继节点。为了减少解码出错率，算法采用了一种主动机制，该机制依据源节点的发射功率和源信息的大小来控制终端的解码出错率，提高网络解码能力。实验仿真对比结果表明，提出的网络编码算法能够有效控制网络编码的出错率，并能有效减少网络开销。

For the problem of energy cost of a large network coding algorithm and the decoding error rate, a multi-channel network coding-aware active mechanism algorithm is proposed, which establishes the system model to analyze network coding work. To minimize sample as consideration, it uses multiple methods to examine the perceived channel coding effect relay node, to make network study from the effect of the relay node encoding, which will send the source information to code better relay node. To reduce the error rate of the decoding algorithm, it uses an active mechanism that transmits power according to the size of the source node and the source information to the control terminal of the decoding error rate, improving the network decoding. The simulation comparison results show that the proposed network coding algo-rithm can effectively control the network coding error rate, and can effectively reduce network overhead.
