摘要
This article mainly proposed centroid weighted average location algorithm because the result of current wireless sensor network node positioning algorithm is not centralized. According to the cross-correlation algorithm, after obtain many group time difference of TDOA, we can convert them into the distance between two anchor nodes, establishing about the testing node position hyperbolic equations. Using "the Chan algorithm" and "the least squares method" to solute hyperbolic curve equation; and using the results of these two types positioning as initial value of centroid weighted average location algorithm to secondary locate, can improve the positioning Convergence, so that positioning more centralized.
