Algorithm for Multi-sensors Data Fusion in WSN
Zhenyu Zhao · Journal of Chinese Computer Systems · 2009
The author promotes a WSN data reduction algorithm in order to adapt the limitation of the WSN source.The algorithm increases data fusion layer between sensing application layer and routing layer.In this paper,the sensed data from the sensor nodes are divided into two types.By using the data reduction algorithm,sensor nodes only transfer the emergent data and the changed information of usual sensed data to sink node.And the sink node recruits the full sensed data.Finally,we implement the data reduction algorithm in TinyOS.Experiment results show that the data reduction algorithm can save energy without losing the sensed information.
