Abstract

Abstract: The estimation of average hop distance plays a dramatic important role in the DV-Hop localization algorithm and has great influence in the accuracy. In order to reduce the estimation error, taking into consideration global and local network circumstance, the hop estimation between unknown nodes and anchor is improved. Simulation results show that the proposed algorithm is effective in improving the accuracy of localization.

Key words: wireless sensor network, localization algorithm, DV-Hop, average hop distance, hop estimation
