Data mining is a very important step of knowledge discovery and it is through the establishment of mining model and through the implementation of the corresponding algorithm to complete knowledge formation. This paper analyzes the advantages and disadvantages of the management information system of wireless sensor networks protocols. Data mining tools can find association rules that satisfy the condition. The paper presents constructing of information management system on wireless sensor network protocol based on knowledge data association mining. Experimental results show that the proposed method can improve the efficiency of routing protocol.
