دانلود Study on Data Fusion Techniques in Wireless Sensor Networks

Abstract

In wireless sensor networks or WSNs, to improve the accuracy and correctness of the target sensing and monitoring, individual nodes often have overlapping sensing ranges. This usually generates data redundancy and results in both time and power consumption especially when large amount of similar data are to be transmitted. Data fusion scheme takes the advantage of this overlapping feature and can reduce, delete and refine the redundant data in the process of data transmission. A survey is presented in this article studying on the data fusion techniques in WSNs from the aspects of cluster based schemes, chain based schemes to statistics based schemes. Their advantages and disadvantages are also discussed in this research.
