Abstract:

The DVHop algorithm is a classical algorithm for node localization in wireless sensor networks. In this paper, an improved algorithm is proposed based on the classical DVHop algorithm to reduce the positioning error accumulated in the multi hop process by introducing a better error correction and the hyperbolic location algorithm. After comparing and analyzing the classical DVHop algorithm and the improved algorithm, the simulation results show that the improved DVHop algorithm can improve the positioning accuracy significantly, with the positioning error reduced by about 50% under the given conditions.
