An Improved DV-Hop Algorithm Based on Entropy for WSN
Localization is one of the key technologies in wireless sensor networks. In this paper, the improved algorithm is derived from DV-Hop algorithm, and uses entropy weight to improve localization accuracy without needing an additional hardware device. Simulation results show that the improved DV-Hop algorithm can provide more accurate location estimation than the DV-Hop algorithm.
