Abstract :
DV-hop algorithm is analyzed in this paper, and then a kind of improved algorithm is proposed based on the errors of estimating average per hop distance and calculating unknown node location by multilateral law. When calculating average per hop distance, it should combine overall average per hop distance and average per hop distance of original DV-hop algorithm. When locating unknown node, it should add weight to amend the result. Location performance under different communication radius and anchor proportion is analyzed and emulated. The result indicates that location precision of improved algorithms has been improved obviously.
