Wireless sensor network is a data centric distributed self-organizing network. The transmission of data is the most important task of it. It is a topic worthy of study that how to ensure the reliability of data transmission in any environment .Fountain codes algorithm is simple, and has no ratio. It is very suitable for coding scheme for Wireless Sensor Networks. This paper mainly studies the Fountain codes of Raptor codes in wireless sensor network data transmission technology, and gives the concrete scheme and implementation ways. The application of this technology can improve the reliability of data transmission and transmission efficiency. It overcome the problems of very large packet error codec technology traditional rate and the decoding success rate.
