%X Localization is one of the key technologies in wireless sensor network. Only the average one-hop distance estimated by the nearest anchor was used in DV-Hop localization algorithm, but the value estimated by a single anchor can not reflect the whole network’s actual average one-hop distance. A novel algorithm is proposed to estimate the average one-hop distance based on weighted disposal. The average one-hop distance estimated by several anchors is used in this algorithm and assigned different weights according to the hops to the unknown node. The unknown node’s average one-hop distance is estimated more accurate and the localization precision is improved. Simulation results demonstrate that the average one-hop distance is estimated more exactly in the proposed algorithm than that of DV-Hop, the root mean square error is decreased and the location precision is improved.
