Localization is increasingly becoming the focus of research in the filed of Wireless Sensor Networks (WSNs), as the data reported from a sensor is only useful when the position of that sensor is found. In this paper, we proposed an improved CPE (Convex Position Estimation) localization algorithm that reduces the localization error without requiring additional hardware and computational costs. In the proposed scheme, we first estimate the location of sensor nodes using Convex Position Estimation (CPE), and then refine the location of sensor nodes using the location of the two-hop anchor nodes. The simulation results show that the new localization algorithm effectively improves the positioning accuracy compared with the traditional CEP localization algorithms.
