Positioning Parameter Research and Performance Analysis for Wireless Sensor Network Based on Centroid Algorithm
Centroid localization algorithm is a typical algorithm in wireless sensor networks. Analyzes centroid localization algorithm and free space propagation model. Then distributes the unknown nodes and anchor nodes randomly in the grid, by changing the number of anchor nodes and communication range, analyzes the effects of the parameters like the number of anchor nodes and communication range on the posi-tioning error. The test results indicate that when the total number of nodes is fixed, anchor nodes and communication range would opti-mize the positioning accuracy.
