Research on Wireless Sensor Networks with an Improved DV-Hop Localization Algorithm Based on Weighted Processing and Error Modification

Abstract:

Regarding the conventional DV-Hop algorithm easily caused big error in a network topology scenario, this paper proposes an improved DV-Hop localization algorithm comprehensive consideration of all anchor nodes average one-hop distance and normalized weighted, use anchor nodes as unknown nodes calculating error and use the error optimizing accuracy. Theoretical analysis and simulation results show that the proposed algorithm has better locating performance in locating precision and precision stability.
