In order to locate the geographic positions of random distributed nodes in wireless sensor networks more efficiently, a new localization algorithm C3HR (concentric triple-hop of node communication range) is proposed in this study. C3HR aggressively extracts both positive and negative geographic constraints from the wireless link layer. The algorithm then simultaneously sets up and solves these constraints to determine node locations with the aid of a small number of anchor nodes. The result of analysis and simulation shows that the proposed C3HR algorithm can optimize the constraints on nodes’ positions prominently, increase the estimation accuracy and localization coverage significantly with sparse and non-uniform anchor distribution, decrease the energy consumption of sensor nodes accordingly.
