| Abstract: | In order to reduce the node localization error of DV-Hop algorithm in Wireless Sensor Network (WSN), a calculation method of average distance per hop was adjusted by using the shuffled frog leaping algorithm. The improved DV-Hop algorithm makes the average distance per hop closer to the actual value, thereby reducing the localization error. The simulation results indicate that the improved DV-Hop algorithm reduces localization error effectively and has good stability without additional devices; therefore, it is a practical localization solution for WSN. |
