OD Model: A Data Correlation Model Based on Spatial Location in Wireless Sensor Networks
Na Li, Yuanan Liu, Fan Wu, Bihua Tang · 2010
In wireless sensor networks, sensor nodes are densely deployed for environmental monitoring, so the observation random data are highly correlated in space. This paper proposed a WSN data correlation model named OD Model based on spatial location according to the most universal mode of omnidirectional Boolean sensing. Both analysis and simulation results show that the accuracy estimation of OD Model is sensitive to the control parameter, and the effectiveness of OD Model is also be proved.
