Research on the Mixed Agorithm of Weighted Centroid and DV-Hop

Abstract

With the advent of intelligence, sensors has been widely used to obtain information, and the research on location of sensor nodes has become a hot spot. This paper integrates the advantages and corrects disadvantages of Weighted Centroid localization algorithm and DV-Hop localization algorithm in fixing position of nodes. Through Matlab simulation test, whether the total number of nodes is fixed and the proportion of beacon nodes is variable, or the proportion of the beacon nodes is fixed, the total number of nodes is variable, the algorithm reduces the error in locating nodes to be fixed, and improves the positioning accuracy.
