Wireless Sensor Network Data Fusion System Design

Wireless sensor network data fusion system could effectively fuse data to reduce redundant information to exchange. It could save the energy of network and prolong the life time of network.At the same time, wireless sensor network data fusion system can provide visual human-machine interface. With the data fusion function, the system could show the administrator visual view of collected data from network, so that administrator could not suffer in amount of data but pay attention to the area where should be noticed. Through the system, administrator could get the current condition of environment which WSN is monitoring, also the change trend of the environment which is represented by the collected data change trend. According to the trend, system or administrator could make a decision that if there is any danger if the trend would be going on. Then some necessary steps should be done.WSN data fusion system could dynamically adjust the parameters of nodes for collecting data and metrics of routing method. So that interest driven data fusion and routing could come true.The method of wireless sensor network data fusion system design is mainly discussed here. Several subjects which need to be considered in WSN data fusion system design are analyzed, including the designing and choosing data fusion algorithm, the designing and choosing data fusion routing algorithm, the design method and notes of system software architecture, etc. Every problem needed to discuss of each subject is analyzed here, including the solvent and design method. The content of this paper could be the basis of engineering development of data fusion system.The subjects above will be discussed in the following sections.
