An Improved DV-Hop Localization Algorithm in Wireless Sensor Network

In order to improve the DV-Hop algorithm performance, based on the characteristics of the DV-Hop this paper puts forward an improved wireless sensor network localization algorithm called FDV-Hop. In FDV-Hop localization algorithm, average hop size of all ANodes were weighted by the UNode to determine its own average hop size, and the triangulation method based on validation was used to calculate the coordinates of the UNode. Simulation results show that FDV-Hop algorithm achieves better performance than DV-Hop algorithm by reducing the location error and improving the location accuracy.
