Abstract: 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 algorithm can effectively control the network coding error rate, and can effectively reduce network overhead.
