Summary:In order to achieve the geographic positions of random nodes in wireless sensor networks more efficiently and aiming at the defect that poor accuracy and coverage of traditional bounding box approach, a new localization algorithm was proposed based on concentric triple-hop of node communication range. The result of simulation and analysis shows that the proposed algorithm can optimize the constraints on nodes’ positions prominently, increase the estimation accu- racy and localization coverage significantly with sparse and non-uniform anchor distribution, decrease the energy con- sumption of sensor nodes accordingly.
