Hierarchical Data Fusion in WSN Based on Mobile Agent
Sheng Zhang, Hui Xin Yang, Hou Jin Xiong · Applied Mechanics and Materials · 2014
We put forward hierarchical data fusion in WSN, in which different fusion algorithm is used in each logic layer. The singular values are kicked out before data fusion with QCP (Quantization coding on precision) method in the cluster, while Difference comparison fusion algorithm are used between cluster head nodes. Mobile agents are used in above two layers. Simulation results demonstrate that the algorithm improves the accuracy of the data integration, lower power consumption and extend the life of the network.
