Research of multi-type data fusion in sensor networks
无线传感器网络中多类型数据融合研究综述

This paper focused on the new problems of multi-type data fusion. By analyzing the correlation, it explored the correlations of multi-type data which were available for data fusion, proposed the concept of multi-type correlation, and reviewed the current situation of data fusion research that was based on correlation. It also gave the general process of research on multi-type data fusion, and then reviewed related literatures acoording to the general process. It analysed and compared various kinds of technologies. At last it pointed out the difficulty and sally ports of the problems, and gave the future key points of the research.
