摘要
Localization is one of the supporting technologies in wireless sensor networks. To enhance positioning accuracy of wireless sensor network node, an improved positioning algorithm is put forward based on the DV-Hop algorithm, A differential error correction scheme, in which average per hop distance of the position network and modified value of distance error are introduced, is proposed in this paper to reduce cumulative distance error and node location error accumulated over the multiple hops. Simulation results show that the proposed algorithm can increase location accuracy obviously and is applicable to asymmetrical network scene.
