Robust DV-hop algorithm for localization in Wireless Sensor Network

In this paper, we propose a novel localization algorithm in Wireless Sensor Network. The proposed method is a kind of range-free localization algorithm which only uses the proximity information between sensor nodes. In the proposed method, a robust weighted algorithm is presented to calculate the average hop distances between sensor nodes and anchor nodes. The proposed method is applied to an isotropic network and three anisotropic networks. The simulation results demonstrate that the proposed method shows excellent and robust location estimation results.
