Abstract

Sensor localization is one of the supporting technologies in wireless sensor networks. The paper introduces the localization process of sensor nodes of DV-Hop algorithm. DV-Hop is one of the range-free localization algorithms using hop-distance estimate. An improved DV-Hop positioning algorithm uses grey correlation method to improve localization accuracy without needing an additional hardware device. Simulation results show that the improved DV-Hop algorithm outperforms the original DV-Hop algorithm and can provide more accurate location estimation.
