| Summary: | In this paper, a new law is found in DV-Hop which is a classic algorithm based on range-free localization algorithm in WSN (Wireless Sensor Networks).There are stable distribution rules in both the locations of the unknown nodes with similar localization error and the locations of the beacon nodes with similar hop-size. Based on this law, the analytical reason is given and an improved localization algorithm is proposed to enhance the localization accuracy. The main idea is revising the hop-size according to the law and applying appropriate algorithm according to the location of the monitor area. The simulation experiments show that the new algorithm can improve the localization accuracy efficiently.
