The Research And Implementation Of The Data Agent System Based On Wsn

With the continuous advancement of current society and the development of science and technology, there is emerging a large number of data information every day; data agent system can convert these data to the information which is demanded by users. Currently, the existing data agent systems mainly use the traditional cable network technology at home and abroad. Howevew, there are some difficulties such as deployment trial, maintenance difficulties, the poor performance of the late extension. Therefore, people start to research the data agent systems based on the wireless sensor network.This paper focused on the study of the problems of data processing in the fields of wireless monitoring, putting forward the data agent system based on wireless sensor network. We conducted real-time data acquisition in the monitoring area, proceeded data transfer processing in the proxy server, received data and sent instructions through data proxy client. In this paper, the system we designed aims at the research and development of windows environment. Through deep research of the theory and key technology in wireless monitoring, we have achieved the exploitation of server and client systems based on WSN data. This system can be used in the fields of family security and farmland monitor etc., the market value and application prospects have been paid more and more attention by enterprises and institutions。The main work of this paper:1. We carried on the overall architecture design of the system based on the demand analysis, studied the characteristics of wireless sensor network which included network deployment and the methods of data acquisition; finally put forward the modified project which was suitable for the system of this article.2. In terms of network transmission, we have carried out further study of the characteristics of each part from physical layer to application layer, conducting the research of technology and methods which are needed in the system designed in this paper. The designed server and front-end equipment in this paper adopt UDP transmission, the client and server using TCP transport. We mainly analyze and investigate TCP/IP protocol, the Socket programming technology and multithreading technology.3. We designed and implemented the server and the client proxy based on WSN data system in this paper, processing data information separately by the ways of designing data channel and controlling channel, using multi-threading technology to process synchronization problems. Under the premise of data flow, the client can send control instructions and obtain other data information.
