In the proposed method, nodes can change its gathering path to adjust the overhead environment. All the nodes of WSN equipped with a learning automata. These leaning automata learn all the gathering path of the nodes. In the process of transmit information two kinds of data are transmitted, including data packet, knowledge packet .When the information of the nodes changes, according to the feedback of the nods, the learning automata gives the reward or punish to the current gathering path, which help to find the best gathering path. Secondly, this paper improved the wavelet data compression algorithm, which was brought out as the correlation between different data. The algorithm do not reduce much of the data relate to the original data. After the wavelet data compression, Huffman coding compression algorithm will improve the data compression ratio.10aData compression10aGatherting path10aHot node10aLearning automata10aWavelet Transform1 aLuo, X.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84879075413&partnerID=40&md5=96bdcc7d815f35b35316761219475c3d
