Localization technology is one of the key technologies in wireless sensor networks(WSNs).On the basis of analysis of the DV-Hop algorithm
an improved algorithm CBDV-Hop is brought out.The concept of collinearity is introduced into the algorithm.The algorithm sets a threshold of collinearity
and selects the high quality beacon node to estimate the position.Theoretical analysis and simulations experiment show that the algorithm can improve the localization precision.
